Connecting to Oracle gives ORA-12650

How can I connect to an Oracle database using the oracle advanced security option (ASO)? When I try to connect to the database using the ojbc:oracle:thin:@host:port:sid, the data source verification fails with the following error. The database I am trying to connect to has been set up to use the Oracle Advanced security.

Connection verification failed for data source: test_uadsrs03
[]java.sql.SQLException: Io exception: Oracle Error ORA-12650
The root cause was that: java.sql.SQLException: Io exception: Oracle Error ORA-12650

I have searched the knowledgebase with no success. Is anyone able to help with this error?

Thanks
