Symptoms

Current working environment using Active Directory (AD) -> Oracle Internet Directory (OID) synchronization and the OID External Authentication plug-ins for AD compare and bind operations.

Most synchronized users can perform 10gAS SSO login successfully; but, for some users, SSO login fails with error:

Unexpected error. Authentication Failed.
