11g New Feature - SYSDBA authentication gets stronger

The SYSDBA & SYSOPER authentication gets stronger from 11g; Oracle now extended support for PKI, Kerberos and Radius to SYSDBA and SYSOPER connections. Earlier, this was limited to all users except SYSDBA and SYSOPER. A new initialization parameter LDAP_DIRECTORY_SYSAUTH has been introduced which needs to be set along with LDAP_DIRECTORY_ACCESS for stronger SYSDBA authentication.

You login as SYSDBA the following way if you configure Directory authentication (OID) :-

CONNECT user@11glab AS SYSDBA
Enter password: password

If you have used Kerberos or SSL then connect as SYSDBA the following way :-

CONNECT /@11glab AS SYSDBA
