Database authentication through OID users

Hi ,

I have OID 11g   configured for TNS names resolutions. And I want to use the same OID for Database login  authentications.

I followed the below steps to  register  DB to use  OID for user authentication

1.  I  updated the sqlnet.ora with following contents

          NAMES.DEFAULT_DOMAIN = <domain.com>

          NAMES.DIRECTORY_APTH  = (LDAP,TNSNAMES)

2.  Updated the ldap.ora with the following contents 

          DIRECTORY_SERVERS = (oid.domain.com:3060:3131)

          DIRECTORY_SERVER_TYPE = OID

          DEFAULT_ADMIN_CONTEXT = "dc=domain, dc=com"

3.  Set the TNS Admin  variable and ran the 12c DBCA and  selected the following options to register the database with OID.
