sap_swpm: Replace SAP detection fail with warning for wrong GID and UID

[marcelmamula]

Changes

#1213 brought a lot of improvements including much stricter validations.
One of them was bit too strict as re-testing has showed that sapinst has some leniency when handling existing users and groups.

• Change fail modules to debug to show WARN instead.

Test results

Summary: Very lenient in accepting IDs from inifile and raises issue only for shared filesystems.

Accepts:

• Existing users sidadm and sapadm with different IDs.
• Existing group sapsys with different ID.

Rejects:

• Existing files under user with different group ID. Example: ASCS with ae1adm GID: 3333 and ERS with ae1adm GID: 3334
  NOTE: This is specific only to distributed systems with shared filesystems!

Group sapsys exists with GID 3334, while the default profile /sapmnt/AE1/profile/DEFAULT.PFL is owned by GID 3333. <br>SOLUTION: Change the GID of group sapsys to 3333 or remove the group account.

HANA Details

• No changes to strict validation of sap_hana_install, because of its own strict behavior documented in test section below.

Test results

Summary: Very strict validation that allows only wrong UID.

Accepts:

• Wrong UID with correct GID and correct sidadm password provided in parameter file under password=

Rejects:

• Wrong UID with wrong GID and correct sidadm password provided in parameter file under password=

The defined user 'h01adm' already exists on the system. Neither the password, nor any other attribute of the user will be changed.
Verify that the user is correct.
Running in batch mode
  Group ID '2001' for 'sapsys' is invalid because 'sapsys' already exists with ID '3335' on the local host

• Wrong UID with wrong GID and missing sidadm password provided in parameter file under password=

The defined user 'h01adm' already exists on the system. Neither the password, nor any other attribute of the user will be changed.
Verify that the user is correct.
Running in batch mode
  Mandatory parameter 'password' (Password) is missing or invalid
