An OAM-OIM integrated environment exists. OAAM was then added to the integration. Following this integration, users were able to enter their username and move to the password screen. However, upon submitting their password, the user is brought back to the login page with the following error being shown in the OAAM log:


[2014-07-22T00:41:10.154-05:00] [wls_oaam1] [ERROR] [] [oracle.oaam] [tid: [ACTIVE].ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: ] [ecid: 004zg6esYH87u1C5NFT4ie0005Co00000I,0:3] [APP: oaam_server#] [DSID: 0000KTS__Pb6uHC5NFT4ie1JnKm100001y] [URI: /oaam_server/] Error loading plugin instance for[[ java.lang.SecurityException: User: xelsysadm, failed to be authenticated.

There were no errors logged in OIM or OAM side. The following error is reported only once when the OAAM Server is restarted:

[2014-07-22T02:03:11.100-05:00] [wls_oaam1] [ERROR] [] [oracle.oaam] [tid: [ACTIVE].ExecuteThread: '3' for queue: 'weblogic.kernel.Default (self-tuning)'] [userId: ] [ecid: 004zgBGCJr27u1C5NFT4ie0005Co00000B,0:3] [APP: oaam_server#] [DSID: 0000KTSsMp56uHC5NFT4ie1JnWea000006] [URI: /oaam_server/] Error loading plugin instance for[[

After the server is started, there are no longer any occurrences of this error.

The issue is seen only for new users who's password needs to be reset. It is not noticed for users with obpasswordchange flag set to false.
