WalkthroughThe authentication system now uses ChangesToken-origin authentication
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR adds direct NGC API-key authentication, but the current implementation can collide service-key and legacy-token identities in shared user records, potentially applying the wrong authorization data; it also leaves upstream response size unbounded and can prematurely fail or temporarily block valid credentials. These concrete authentication and availability risks make the PR not merge-ready until corrected. Sequence Diagram(s)sequenceDiagram

46-61: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winFlatten the redundant loop and switch.
The loop iterates over exactly the four constants that the switch then matches one by one. The indirection adds nesting without adding behavior. Straight-line registration reads better and removes the possibility of the slice and the switch drifting apart.
The conditional KAS-origin registration below is correct, and it matches the middleware, which also gates on the presence of a KAS-origin processor before it routes a non-JWT bearer.

Add a kas issuer origin that accepts NGC API keys as bearer credentials and resolves them to a NICo user via NGC, so clients are not forced through a separate JWT exchange. Supports nvapi- personal and service keys and base64 legacy keys; caches by key digest with NGC 401/403 blocking and single-flight deduplication. Signed-off-by: Parham Armani <parmani@nvidia.com>
`newResolver` and `NewKasOriginProcessor` each returned an error whose only source was `freelru` cache allocation. That constructor rejects a non-positive capacity, a capacity larger than the size, and a nil hash function -- all three fixed by the compile-time constants at the call site, so no reachable input can produce a non-nil error. `newResolver` now panics on that branch instead. The processor is non-nil by construction, `NewKasOriginProcessor` matches the signature of its four sibling constructors, and if the capacities ever become configurable the failure surfaces at startup rather than silently rejecting every NGC API key with a 401. Signed-off-by: Parham Armani <parmani@nvidia.com>
The kas origin authenticates NGC API keys, which are not JWTs, so the type that owns every bearer-credential origin can no longer be named after JWTs. Renames the type, its constructor, the `GetOrInit` accessor on `Config`, the `Config.TokenOriginConfig` field, the `joCfg` parameter and `jc` receiver names, and the `jwtOrigin.go` / `jwtOrigin_test.go` files. No behaviour change: every hunk is an identifier or filename, plus the gofmt realignment of the `Config` struct that the longer field name forces. Signed-off-by: Parham Armani <parmani@nvidia.com>
The user record embedded in get-caller-info is scoped to the org the key was minted in, so it under-reported membership for owners belonging to more than one org. Personal keys now call /v2/users/me, which returns the full set. That set is broad in practice, since an NGC user usually belongs to many orgs unrelated to NICo, so filter it to the orgs whose roles actually grant access. The filter runs through ValidateUserRolesInOrg against config.AllowedRoles so it cannot drift from what authorization enforces.
detectAPIKeyType is a local constant-cost check, so blocking on its failure let an unauthenticated caller write into a shared 4096-entry structure. Each garbage bearer evicted a genuine NGC-derived verdict and restored an NGC round trip for a key NGC had already rejected. Rejecting on format before hashing reserves the block cache for verdicts that cost an NGC call, and skips the digest for input that cannot be a key.
The comment named HandleToken, so godoc for the exported method did not begin with the method name and generated misleading documentation.

Consider separating "rejected" from "forbidden" before blocking the credential.
do maps both 401 and 403 to errNgcUnauthorized. In refresh, that verdict writes the digest into blockLRU for blockLifetime. A 403 from NGC is not always a statement that the credential is invalid; it can also indicate a policy or scope decision on the specific endpoint, or an edge-layer denial. In that case a valid key is hard-blocked for five minutes, and the caller receives 401 with no retry path.
If NGC returns 403 only for invalid credentials on these endpoints, keep the current mapping and record that fact in a comment. Otherwise, treat 403 as errNgcUpstream so it degrades to 503 instead of poisoning the block cache.
As per path instructions: "Review auth changes for JWT/keycloak behavior, token validation, authorization boundaries, service-account handling, and secret exposure risk."

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
fetchTimeout is overloaded as both a per-call and a whole-operation budget.
Line 365 gives the entire leader operation fetchTimeout (10s). The same constant is the per-request http.Client.Timeout at Line 332. The leader work is not a single request:
formatNvapi+ service key:get-caller-info, thenget-sak-info, thencreateOrUpdateUser.formatNvapi+ personal key:get-caller-info, then/v2/users/me, thencreateOrUpdateUser.
If the first NGC call consumes most of the budget, fetchCtx expires during the second call or during the database write. The failure surfaces as errUnresolvable and a 503, and every waiter on the same singleflight key receives it. One slow NGC response therefore fails the whole resolution instead of the individual call.
Give the operation its own budget, sized for the sequential calls plus the database write.

Namespace SAK and KAS identifiers before storing them in AuxiliaryID.
The service-key path stores the raw info.APIKey.KeyID, while the legacy KAS path queries and updates the raw JWT subject. Both paths use the same unique AuxiliaryID column, and the legacy workflow replaces OrgData. Equal values can therefore make distinct credentials share a user record and authorization data. Use distinct prefixes such as sak: and kas: before persistence.

In `@rest-api/auth/pkg/processors/kas.go` around lines 476 - 482, Update
createOrUpdateUser and the service-key/legacy KAS persistence paths to namespace
AuxiliaryID values before calling userDAO.GetOrCreate or updating the user:
prefix SAK KeyID values with “sak:” and legacy JWT subject values with “kas:”.
Ensure all subsequent queries and updates in each path use the same prefixed
identifier, while preserving existing authorization and OrgData behavior.

NICo only accepted JWTs as bearer credentials, so a client holding an NGC API key
had to exchange it for a token before it could call the REST API. This adds a
kasissuer origin that accepts an NGC API key directly and resolves it to a NICo user
against NGC, covering
nvapi-personal and service keys as well as base64 legacy keys.A personal key resolves through
/v2/users/me, which reports every org its ownerbelongs to. A service key resolves through
get-sak-info, whose policy set is whatgrants the NICo provider or tenant admin role;
get-caller-infois used only to tellthe two apart, because the user record it embeds is scoped to the org the key was
minted in. Resolutions are cached by key digest, keys NGC rejects are blocked for five
minutes, and concurrent resolutions of the same key are deduplicated so a burst costs
one upstream call.
Also renames
JWTOriginConfigtoTokenOriginConfig, since that type now owns anorigin whose credentials are not JWTs.
