When I trying to allow Login Oracle with the OS Authentication it gives err. It was successfully working with Win 2000 professional, but the same thing when I tried in Win 2000 Advance Server. It gives me the following error msg.
ORA-01004: default username feature not supported; logon denied.
I am also giving the respective changes made in my database.
OS_AUTHENT_PREFIX = "OPS$"
Created Database User
create user OPS$OSAdmin identified externally;
grant connect to OPS$OSAdmin;
Please help me the get through this problem. I to believe to take Backup from OEM its necessary to login through OS Authenticated user.
Thanks in advance for your answers
