How can you login with sysdba when SQLNET.AUTHENTICATION is set to NONE? We have a server that got put into a different domain. In order for users outside the domain to connect, we had to change SQLNET.AUTHENTICATION from {NTS} to {NONE}. With the authentication set to NONE, I can no longer connect as sysdba. Logged into the server as Oracle or myself, I get ORA-01031: insufficient privileges when trying to login in with any of the following combinations: SQL> connect /as sysdba SQL> connect sys/sys_passwd as sysdba SQL> connect sys /as sysdba
The second and third lines listed above should prompt you for the password and allow you to connect, providing your user is in the ORA_DBA group. For RMAN you have to provide the user name and password; c:\sql>rman Recovery Manager: Release 10.2.0.3.0 - Production on Fri Apr 13 11:54:49 2007 Copyright (c) 1982, 2005, Oracle.
