OBIEE 11g Authentication Problem after deploying new RPD , Refresh GUID

Open the BI Server configuration file NQSConfig.ini file from the following location :

\InstallHome\instances\instance1\config\OracleBIServerComponent\coreapplication_obis1

Set the below tag to NO

FMW_UPDATE_ROLE_AND_USER_REF_GUIDS = NO;

And restart your server.

We usually get this error when we deploy a new rpd, bcoz the id (which is unique for every rpd) is not registered with the BI server.
