Today I experienced this trouble with OBIEE: users can't login to BI Presentation Services.
System returned the following error: An invalid User Name or Password was entered.
Although I was perfectly capable of accessing WebLogic Server console and Enterprise Manager console OBIEE didn't let me in.
After a brief investigation in logs located at:
I spotted this error:
WSM-06102 Policy Reference The policy reference URI "oracle/wss_username_token_service_policy" is not valid.
which is an error given by a deplyed component which has gone bad.
This can be verified accessing WebLogic Server Deployment console, wsm-pm component is in error state:
To solve this it's sufficient to re-deploy this component
Click Lock & Edit -> select component wsm-pm -> Update
Click Next -> Finish
Then Activate Changes and verify that wsm-pm can service all requests and is in running state.
Once this is completed you should be able to login to OBIEE presentation Services again!
