I got this error while creating new database using DBCA (Oracle 11gR2). I’ve just fixed it and think worth to mention it here.
Cause: The authentication service failed to retrieve the credentials of a user.
Please check the sqlnet.ora file (ORACLE_HOME\\NETWORK\ADMIN\). Change NTS to NONE and this should work.
Before – SQLNET.AUTHENTICATION_SERVICES= (NTS)
After – SQLNET.AUTHENTICATION_SERVICES= (NONE)
…Till next time
