Error Message For BISystemUser: User not authenticated

Question

We have migrated from DEV to PROD env.(11.1.1.1 -> 11.1.1.3). Along problems with bipublisher - there are some strange thingths: we successfully loging using weblogic account into AdminConsole и Enterprise Manager, but in Answers we get an error: invalid username or password.
nqserver.log:
...[ERROR:1] [] [] ... [tid: 1090] Error Message For BISystemUser: User not authenticated.
...[ERROR:1] [] [] ... [tid: 1090] [nQSError: 43126] Authentication failed: invalid user/password.
In oracle support we found such issue (Doc ID 1308389.1):
OBIEE 11g Error: "Unable to Sign in. invalid username or password was entered" After Changing Repository, Deleting BISystem User, Adding it Back (Doc ID 1308389.1)
Applies to: Business Intelligence Server Enterprise Edition - Version: 11.1.1.3.0 [1905] to 11.1.1.5.0 [1308] - Release: 11g to 11g
Symptoms: In OBIEE 11.1.1.3.0 using default authenticator, it is not possible to log in to OBIEE after changing repository. To troubleshoot, BIsystemuser was removed from global roles and added back again.
Getting error: Unable to Sign in. invalid username or password was entered
Changes: Changed repository, deleted BISystemuser, added the user back
Cause: Several changes e.g changing rpd, deleting bisystem user, adding the user back etc. occurred in the environment and caused log in to OBIEE to stop working
Solution: After a lot of troubleshooting e.g re-starting system in the correct order, refreshing GUIDs, re-start OBIEE with default SampleAppLite.rpd and web catalog, the error persists. The system was uninstalled and re-installed to avoid further corruption and configuration problems in the new installation. This resolved the problem
Does we have to 'reinstall or make a lot of troubleshooting e.g re-starting system ' to solve this error?
It seem to be funny for PROD environment. How we cam resolve this problem?

Answer 1

Are you saying you upgraded both dev and prod from 11.1.1.1 to 11.1.1.3 or that you migrated a dev 11.1.1.1 to a prod 11.1.1.3? What did you migrate?
At a rough guess the BISystemUser password is different in dev and prod (created by system on install) and in your 'migration' you've moved the dev credential across to prod.
If that's the case you need to change the bisystemuser password to something known and update the credential store password.
Another possibility might just be that you need to regenerate the GUIDs:
