…account UserCreationService.createUser set activated = false and generated an activation key for every account it created, including externally managed ones. Course member import, exam registration and admin user import all resolve unknown students through UserService.findUserInLdap, which uses that factory and never activated the result - unlike the LDAP first-login path, which activated the user immediately afterwards. Whether an external account ended up activated therefore depended only on whether the user logged in before an instructor imported them. An activation key is redeemable only through GET /activate, and both that endpoint and the mail carrying the key are gated behind artemis.user-management.registration.enabled, which self-registration also requires. Self-registration always creates internal accounts. So the unactivated state is meaningful only for an internal account on an instance with registration enabled, and creating an external account unactivated leaves an account that nothing can activate. The factory now applies it under exactly those two conditions. The compensating re-activation in LdapAuthenticationProvider becomes redundant and is removed, and User.activated documents the invariant along with the three distinct reasons the flag can be false. The migration repairs affected accounts. It applies only where an activation key is still present: createUser set a key, deactivateUser never does, so an account an administrator switched off cannot match.
The launch flow used activated as its record of whether the account had already been shown the Artemis password generated for it: the launch created the account unactivated, buildLtiResponse added ?initialize because of that, and PUT users/initialize returned a password and set activated = true, so later launches skipped the dialog. An LTI account is provisioned by the launch rather than registered by its owner, so it has to be created activated - which leaves the flow without a marker of its own. Add lti_initialized for it, and key both the query parameter and the endpoint on that instead. PUT users/initialize consequently no longer writes activated. It used to activate the caller when the account was external or not LTI-created, which was a workaround for external accounts being created unactivated. They no longer are, so the only way to reach the endpoint unactivated is for an administrator to have deactivated the account, and reversing that is an administrator's decision. The backfill marks an already activated LTI account as initialised, since it has been through the dialog. An unactivated one keeps the default, so a genuinely uninitialised account still gets its dialog while a deactivated one is not activated by it.
Deactivating an account cuts off every form of access, so who did it and to whom has to be reconstructable long afterwards. Neither route that writes the flag recorded it: the deactivate endpoint goes through deactivateUser, while the admin edit form writes it inside updateUser, so both are audited. A comment in updateUser already stated that the acting administrator is recorded in the audit event rather than emailed to the affected user, which was not yet true. Neither event type joins GENERAL_EVENT_TYPES, so they fall under the retention for deliberate actions rather than being pruned with login records.
…endpoint GET login-options decides whether the login form shows a password field or sends the user to the identity provider. It resolved an identifier it did not find locally against the configured directory, which made the answer depend on that lookup and let an unauthenticated caller drive one directory query per request. It is now derived from local state only: an internal account gets the password form, and everything else - an externally managed account, and an identifier this instance has not seen - goes to the identity provider, which is also where a first-time user is provisioned. An unknown identifier therefore answers exactly like a known external one. The LdapUserService dependency is no longer needed. Rate limiting: the endpoint had no nginx location block, so nothing bounded it at the edge, and it shared the AUTHENTICATION bucket with the login that follows it and with git authentication. It gets its own zone and its own rate-limit type, both at the login budget of 30 per minute, so spending it does not reduce the logins a shared address can perform. GET activate had the nginx limit but not the application-level one, and now uses ACCOUNT_MANAGEMENT like register and the password-reset endpoints.
The page covered the registration configuration and little else. It now describes account types, every path that provisions an account and the activation state each produces, the activated invariant and the three reasons the flag can be false, activation and the cleanup of accounts that are never activated, deactivation against soft deletion, and the rate limits on the account endpoints. It also documented use-external as the switch for LDAP authentication. That property is only reported through /management/info so the client knows where to send a password reset; LDAP is controlled by artemis.user-management.ldap.enabled. The OIDC page existed but was missing from the sidebar.
…rators Follow-up documentation pass over the code this branch touches. JavaDoc: createUser now states the two conditions under which it creates an account unactivated; activateUser and deactivateUser state that the change is audited and that only an administrator can reverse a deactivation; the login-options endpoint and service explain that the answer comes from local account state and why the endpoint has its own rate-limit bucket; buildLtiResponse explains what the initialisation marker keys on. Two JavaDoc comments described behaviour the code does not have: - setRandomPasswordAndReturn claimed to update the password on CI and VCS systems, which it never did. - findUser described looking up the registration number first and interleaving database and directory lookups. It searches the database completely first, and within each stage tries login, then email, then registration number. The admin page gains sections on importing users, the audit entries for account state, and troubleshooting for the symptoms these produce - an account that can sign in but cannot use git, a registration that disappears before it is activated - plus links to the related pages.
The launch establishes a session by writing the security context directly instead of going through an AuthenticationProvider, so it never consulted the account state that the internal, SAML2, OIDC and passkey providers each check, and that both git paths check. A deactivated or soft-deleted account could therefore still be signed in through the LMS, on all three routes: the already-authenticated fast path, the trusted-external-system branch, and an account that already existed under the launch login. PUT users/initialize now also requires the account to be activated. It no longer activates anyone, but without this it would still hand a fresh password to an account an administrator had switched off, using a session issued before that. The account can neither sign in with a password nor use git while deactivated, so this closes the session and the credential rather than an escalation. Only an administrator can activate an account again. Also from review: the login-options nginx comment named $binary_remote_addr while the zone keys on $rate_limit_key, and the import documentation claimed an existing account is refreshed from the directory. It is used as it is, except in the one case where the searched identifier missed locally but the directory resolved it to a login that does exist.
The guard sat at the three points where a launch resolves an account, which leaves the question of whether some launch variant populates the security context by another route. buildLtiResponse is where the session cookie is actually issued, so checking there holds regardless of how the context was populated - in particular for the LTI 1.3 path, which resolves an existing account in Lti13Service without going through createNewUserFromLaunchRequest. addLtiQueryParamsDeactivatedNonLtiUserGetsNoDialog is superseded: a deactivated account no longer reaches the question of whether the dialog is owed, because the launch is refused first. It now covers the case that remains meaningful, an activated account the launch did not create.
…vation-only-for-self-registered-accounts
Recover an LTI account whose first launch never finished. Under the old flow the launch created the account unactivated and the initialisation dialog activated it, so an account whose owner closed the launch before that dialog completed stayed unactivated. It could still launch again, because the launch did not check account state - it does now, which would have left exactly this population unable to launch at all. last_modified_by separates the two ways such an account can be unactivated: deactivating is an authenticated administrative action and stamps the administrator's login, while an account that never got past provisioning has never been written by an authenticated principal. An administrative deactivation therefore cannot match the predicate. lti_initialized stays false for the recovered rows, so the dialog is still owed - the state the old flow would have left them in. Emit one audit event per activation. AdminUserResource.updateUser follows an activating update with userService.activateUser, and both were recording the same transition. updateUser now audits only the deactivation, which is the direction that has no other route. Also merges develop and keeps the changelog includes in chronological order, which the automatic merge had not preserved.
LdapAuthenticationProvider authenticated an existing external account and returned it without consulting activated or deleted, so correct LDAP credentials were enough on their own. It was the last authentication path that did not check: the internal, SAML2, OIDC and passkey providers all do, as do both git paths and now the LTI launch. An account an administrator had deactivated could therefore still obtain a web session. Deferred until now on purpose, because enforcing it before the accounts the student import left unactivated were repaired would have locked those users out. The migration that repairs them is in this branch and Liquibase runs at startup, before anything can authenticate, so the two are safe to ship together. The check runs after the LDAP credentials have been verified, so the outcome cannot tell an unauthenticated caller anything about an account. The documentation and one code comment described the old behaviour in the present tense and are corrected; the enforcement list now names every provider.
The endpoint read ltiInitialized and only later saved the rotated password, so two concurrent launches could both pass the check, both rotate, and each return a plaintext password. Only the hash saved last remains valid, so one of the two users is shown a password that does not work. Express the transition as a conditional update instead. Only the caller that flips the marker from false to true issues a password; a caller that finds it already claimed is answered like an already-initialised account. The in-memory flag is still set before the password is saved, so that save does not write the stale false back and undo the claim. Tested through the repository rather than with threads, which would be flaky: the claim returns 1 then 0 for the same account, and removing the condition from the query makes that test fail.
The previous fix still split the protected transition in two: the claim committed, and the password was then written by saving an entity that had been read before it. That save writes every field, so an administrator deactivating or soft-deleting the account in between would have their change overwritten and the account handed a working password. A failure while hashing or saving also left the marker set although no password had been delivered. The password hash and the marker now move together in one conditional update that carries the account state in the same statement, so a racing deactivation either commits first and the update matches nothing, or commits after and stands. The hash is computed before the statement runs, so a hashing failure changes nothing. The plaintext is returned only when the statement applied. The read in the endpoint stays as a fast path, sparing an ineligible caller the cost of hashing, but it is no longer what protects the transition.
Drops the lti_initialized column and every LTI change that followed from it. The column widened jhi_user for a case this branch was never about, and LTI was only ever pulled in because the activation gate had been written as "internal account and self-registration enabled", which changes what the LTI launch sees. The gate is now on the account type alone: an externally managed account is created activated, an internal account keeps the behaviour it had. LTI is the only caller that creates an internal account through this factory, so its flow is untouched and needs no marker of its own. Reverted with it: the launch and cookie account-state guards, the atomic password initialisation, the recovery migration, and their tests. Each addressed something real, but none of it belongs in a change about accounts created by the student import. The documentation records why narrowing to self-registration is a separate change rather than pretending the condition is enforced. Kept: activating the externally managed accounts the import left behind, the audit entries for activation changes, the login-options and rate-limit work, and the LDAP account-state check.
PUT users/initialize activated the caller whenever the account was externally managed or not created by an LTI launch. The endpoint only requires an authenticated session, and a session issued before a deactivation keeps working, so any such account could undo an administrator's deactivation by calling it. That branch now answers without modifying the account. Only an LTI-provisioned internal account still reaches the password initialisation, which is the case the endpoint exists for and keeps behaving as before. Requiring the LTI module to be present is a deliberate tightening: with LTI disabled nothing reaches this endpoint, since the client only calls it in response to the initialize parameter the launch adds. A deactivated account that the launch itself created is not covered. Separating "already initialised" from `activated` is what that needs, which is a follow-up.
First cluster of the effort to stop jhi_user carrying rarely-populated special-case columns. The table has 29 columns, roughly 13 of them set on under seven percent of rows, and several owned by other modules. The personal VCS access token is the natural first one: 60 of 34,354 accounts have one, and the participation- and repository-scoped tokens already live in tables of their own, so this was the last of the three still stored inline. user_vcs_access_token uses user_id as its primary key, which expresses the one-to-one in the schema and needs no extra unique index. A row exists only for an account that has a token, so the absence of a row means what a null column meant before. Nothing on User points back at the new entity: a user load can therefore never pull the table in, and there is no lazy association to initialise outside a session - the problem UserCourseRole needs its isCourseRolesLoaded escape hatch for. UserVcsAccessTokenService resolves "no row" in one place rather than handing callers an Optional whose forgotten orElse would look like a working path. The two columns on jhi_user are left in place and only deprecated, so that nodes still running the previous version keep working through a rolling deployment. A follow-up drops the columns and the fields together, as 20260518120000 staged the course-groups refactor. Fixed along the way: authenticating with a participation token copied it onto the in-memory user, and resolveHTTPSAuthenticationMechanism runs afterwards and compares the presented secret against the user's own token - so the access log recorded USER_VCS_ACCESS_TOKEN for what was a participation token. Reading the personal token from its own table removes the confusion.

Development: Move rarely-populated special-case columns out of jhi_user
A repository must not reach into a service, and moving the last-login write behind UserActivityService made CustomAuditEventRepository do exactly that - AdminRepositoryArchitectureTest fails on it. The create-the-row-first fallback moves to UserActivityRepository as a default method, next to the update it falls back from, and the audit repository calls that. The service keeps the same API and delegates. Two concurrent first writes for the same account both find no row and both insert one, so the loser now retries the plain update instead of losing the timestamp. An account provisioned by an LTI launch kept the activation key createUser issues for every internal account. It never receives the activation mail, so the key was a link nobody sent that still flips `activated` back on. The launch drops it again, as the code it replaced did, and the two redundant saves of a user that createUser had already persisted are gone. Deactivating an account and soft-deleting one now drop any outstanding activation or reset key: both take control of the account away, and a pending key is a way back in. Deliberately not done for an administrative password change, which revokes credentials too but must leave an administrator-created account's invitation keys intact. Presenting no key at all matched a row that held only the other key, because a derived query turns a null argument into IS NULL. Both finders reject a blank key. findByVcsAccessTokenExpiryDateBetween and updateUserVcsAccessToken read and wrote columns nothing populates any more and had no callers left; a future caller would have silently done nothing. Also: the decision of a post's author was read twice per forwarded post, answerAuthorIds was duplicated verbatim in two services and now lives on the DTO that consumes it, and the test fixture recorded its default AI decision for two of eleven account helpers while overwriting a decision a test had set on purpose.

PUT api/account/users/initialize decided from jhi_user.activated whether an LTI-provisioned account still had to be initialised. An administrator uses the same flag to disable an account, so the endpoint could not tell the two apart: a deactivated account looked exactly like one that had never been initialised, and was activated again and handed a working password. Only an authenticated session is needed to reach it, and one issued before the deactivation keeps working. The lti module now records this itself, in the table it already owns. The marker is claimed in a single conditional statement, so exactly one request proceeds and a deactivated account - which was initialised earlier, and therefore carries the marker - finds nothing to claim. The launch offers the dialog on the same signal rather than on `activated`. The password write is one guarded statement as well. It replaces a save of the whole entity the request had read, which wrote every field back and so undid a deactivation or soft delete that arrived in between. Backfilled from `activated`, the only signal the old flow left: an activated LTI account had completed initialisation, an unactivated one had not, and the latter must still be able to finish. Also removes two working notes that were committed by accident. They record production-derived counts and one account's identifier, which does not belong in a public repository.

Neither belongs in the repository. The analysis note records production-derived population counts and one account's login and row id, and Artemis is public; the draft is a superseded copy of the pull request description. What is worth keeping from both is already in documentation/docs/admin/user-registration.mdx and in the inline documentation on the fields concerned.

develop
August 24, 2026 20:22
40 conflict hunks across 12 files. Almost all of them come from one cause: this branch merged the activation branch (#13541) twice while it was still under review, and #13541 then landed on develop as a squash containing the review fixes. For that content develop is the newer intent, so taking this side would have silently reverted the fixes. Taken from develop: * the User.activated javadoc, which had claimed the factory requires an internal account *and* self-registration, and linked a method that does not exist. Only the internal check is implemented. * the best-effort audit write in UserCreationService, and the single DEACTIVATE_USER entry placed after the credential revocation. This side still had the pre-review ordering, so a naive resolution left the call in both places and would have recorded every deactivation twice. * the six audit assertions in AccountCredentialRevocationIntegrationTest. This side carried the pre-review versions, which reference a field and a findAll(Pageable) overload that the audit-log split removed - taking them back would have reintroduced eight compile errors. * the nginx comment fix, and the corrected rate-limit and audit sections of the user-management documentation. Kept from this branch, as the newer model: * activation and reset keys read and cleared through UserRecoveryKeyService rather than the deprecated User columns. * UserResource.initializeUser deciding on the lti module's own marker and claiming it once, which closes the same self-reactivation hole #13541 closed, more thoroughly. * the deprecation notices on the extracted User columns. Genuinely combined, where both sides had to survive: * LocalVCServletService: develop's participation-id projection with this branch's decision not to copy the matched token onto the user. * CustomAuditEventRepository: develop's three audit logs together with this branch's UserActivityRepository; UserRepository is no longer used. * PublicAccountResource: this branch's recovery-key mail recipients together with develop's account-security audit events on every branch. * UserCreationService.storeInitialPasswordAndActivate: the conditional update is this branch's, and the key clearing #13541 added is kept on top of it - the JPQL sets only password and activated, so without this the LTI initialisation would leave a redeemable key behind. * UserTestService: the assertion for that clearing now seeds and reads the key through UserRecoveryKeyService. Left on the deprecated column it would have passed without testing anything. Statements that the LTI launch reads `activated` were corrected to name UserLti.initialized, in User.activated, in the createUser rationale and in the documentation. Verified: compileJava, compileTestJava, spotlessCheck, checkstyleMain and checkstyleTest all clean; 201 of 202 tests pass across the account, audit and architecture suites. The one failure, ArchitectureTest.testFileWriteUsage, is inherited from develop (#13549 added three Files.writeString calls to FileUtilUnitTest) and fails on develop itself.

Do not reactivate an account after an LTI claim.
UserResource.initializeUser claims UserLti.initialized before it calls this method. If an administrator deactivates the account after that claim, this query still matches because deleted is false. It then sets activated = TRUE and stores a password. The deactivated account becomes usable again and the initialization response returns its new password.
Use one account-state protocol for the LTI claim, password store, and deactivation. The password store must reject a claim that deactivation invalidated.

Make preference-row creation atomic.
Two concurrent first writes can both create UserAiPreference for the same userId. One save then fails on the primary key and returns an error to the caller.
Use a conditional insert or an insert-conflict retry that reloads the row before applying the mutation. Cover concurrent recordDecision and setMemirisEnabled calls.

Keep the password update guarded against concurrent deactivation.
claimInitialization does not prevent an administrator from deactivating the account before Line 148. The supplied storeInitialPasswordAndActivate query only checks deleted = FALSE, then sets activated = TRUE. A session issued before deactivation can therefore still restore the account in this interval.
Require the account to still be activated in the guarded update, or include the deactivation state in the same atomic initialization transition. Add an interleaving test for claim, deactivation, and password storage.

Serialize token storage and token revocation.
Line 87 reads the token row before Line 90 writes it. AccountCredentialRevocationService deletes the same row through revoke(userId). If storage reads a row, revocation deletes it, and storage saves the stale entity afterward, the token can be recreated after revocation. Two first-token requests can also insert the same user_id concurrently.
Make store and revoke linearizable per user. Use a shared lock or credential revision across both operations. An upsert alone does not preserve revocation ordering.

Do not restore a cleared AI decision.
clearAiSelectionDecision can leave a user_ai_preference row with a null decision. findDecision also returns null when no row exists. The next user save then writes CLOUD_AI and changes an intentionally undecided fixture.
Add a service method that distinguishes an absent preference row from a row with a null decision. Seed the default only when no row exists.

#13541 was squash-merged, so its changes arrive here as new content on both sides and every file this PR built on top of it conflicted. Resolved in favour of develop wherever the change was unrelated to the extraction - the audit log split, the reviewed wording of the account-lifecycle documentation, the SAML2 rate-limit rows, the git-path query reductions - and in favour of this branch wherever develop reads a column the extraction vacated. Three resolutions were more than a choice of side: CustomAuditEventRepository was rebuilt on develop's version, which now routes events to three logs, with only the last-login write swapped to the activity repository. deactivateUser keeps develop's order, which writes the audit entry after the credential revocation rather than before it; taking both sides literally would have recorded the event twice. PublicAccountResource needs both the recovery keys this branch reads and the account-security events develop records. The git request path lost the derivation of the credential used for the access log. It re-ran the token lookups the authentication had just done, and only arrived at the right answer because the matched participation token was copied onto the in-memory user - the copy this branch removed, which is what made a participation token appear in the log as the user's own. Authentication now reports which credential matched, so the log no longer re-derives it. The four git query budgets go up by one. The personal access token is compared before the other credentials and reading it is a query now, where it used to be a column on the user row. Guarding the token branches by the shape of the presented secret would have avoided it, but that narrows which stored tokens authenticate at all, which is not a trade this refactor should make. Initialisation also clears any outstanding activation key, so that every write which activates an account leaves the same state behind.
Both sessions resolved the same squash-merge conflicts. Kept this side for the git request path, where the access log now takes the credential from the authentication instead of re-deriving it, and for the query budgets that records; kept the other side's wording where it says the same thing without linking a field the extraction deprecated.

| An LTI launch for a user Artemis does not know creates an internal account and shows that user a dialog | ||
| with a generated password, which is what they authenticate with afterwards. Two things follow from that: | ||
|
|
||
| - The account is created with an activation key like any internal account, and the launch discards it | ||
| immediately. No activation mail is sent for such an account, so a key left in place would be a link | ||
| nobody ever received that still activates the account. | ||
| - Whether the password dialog is still owed is recorded by the lti module itself, in | ||
| `user_lti.initialized`, and never inferred from `activated`. |

Document the pending LTI state in the table.
UserCreationService.createUser(..., true) persists activated = false, and LtiService only clears the activation key. PUT api/account/users/initialize later sets activated = true. Add a pending-LTI row with no activation key and qualify “Only the first row leaves the account unactivated.”

Describe this as at-most-once initialization.
UserLti.initialized prevents a second successful claim. It does not guarantee that every account initializes exactly once. The documented deactivation path can refuse initialization, so an account can initialize zero times. Replace “exactly once per account” with “at most once per account” or define the success condition.

Update the documentation sentence describing the separate marker to state that
initialization happens at most once per account, while preserving the
explanation that UserLti.initialized prevents repeated or concurrent successful
claims.

Reject LTI launches for deactivated accounts.
When trustExternalLTISystems is enabled, LtiService.authenticateLtiUser creates an authenticated token without checking User.activated. Lti13LaunchFilter then calls buildLtiResponse, which creates a JWT cookie. JWTFilter and TokenProvider.getAuthentication do not recheck activation, so the deactivated account can use the session. Reject the launch before authentication or enforce activation during JWT authentication. Add a regression test.

One deactivation through the admin edit form wrote two DEACTIVATE_USER entries. The develop merge is where that came from: develop moved the audit call to after the credential revocation, this branch still had it before, and the merge kept both. It is the same defect that was fixed once already for the activation direction. The audit call now happens in one place, after the revocation, with the recovery-key clearing beside it. Both deactivation tests asserted with anySatisfy, which two entries satisfy just as well as one, so neither could see this. They count now.

Summary
jhi_userhas 29 columns, roughly 13 of them set on under 7% of rows, and several owned by other modules. This moves the clusters where extraction is a clear win into their own tables.user_vcs_access_tokentoken,expiry_dateuser_lticreated_by_launchuser_recovery_keyactivation_key,reset_key,reset_dateuser_activitylast_login_date,deletion_warning_sent_dateuser_ai_preferenceselection_decision,selection_decision_date,memiris_enabledEach uses
user_idas its primary key, which expresses the one-to-one in the schema and needs no extra unique index. A row exists only when there is something to record, so the absence of a row means what a null column meant before.Nothing on
Userpoints back at the new entities. A user load can therefore never pull these tables in, and there is no lazy association to initialise outside a session — the problemUserCourseRoleneeds itsisCourseRolesLoaded()escape hatch for. Each cluster exposes one service that resolves "no row" in a single place, rather than handing callers anOptionalwhose forgottenorElsewould look like a working path.Not dropping the old columns yet
The vacated columns stay, deprecated, so nodes on the previous version keep working through a rolling deployment. A follow-up drops columns and fields together — the staging

isLtiCreatedUserwould have thrown. Reading a boolean column was safe on an unsavedUser; a lookup keyed ongetId()is not. Now null-checked; two existing tests caught it.jhi_userindexed neither column, so both lookups were table scans. The new table indexes both.Also fixed: authenticating with a participation token copied it onto the in-memory
User, andresolveHTTPSAuthenticationMechanismruns afterwards comparing the presented secret against the user's own token — so the access log recordedUSER_VCS_ACCESS_TOKENfor a participation token.The two clusters that first looked not worth extracting
Both were initially dropped after reading the call sites, then done once the objection had an answer.
PyrisPostDTOread the decision off each answer's already-loaded author, so a row per accountwould have meant a query per answer post on an Iris path. It now receives every answer author's decision as one map,
loaded in a single query. An author absent from the map counts as undecided, not as having refused - the other way
round would redact most posts.
updateLastLoginDateis called with only the principal string, no id, which looked like it forcedeither an extra lookup per login or dialect-specific upsert SQL. Neither is needed: the update is a single JPQL
statement whose
WHEREresolves the id through a subquery on the login. The cleanup readers join the table and fallback with
COALESCE(activity.last_login_date, user.created_date).last_login_dateis at 100% fill, so it buys no sparsity - it moves because the write is on the authentication pathand belongs next to the other activity timestamp rather than in the middle of a row that is joined into large result
sets.
