What security risks can be with domain users?
create user "OPS$KA\USERNAME" identified externally. grant create session to "OPS$KA\MARIK";
Then MARIK that is in KA domain, can logon to the database without password.
I wander to know if oracle checks that the user is a really domain user?
For example is there a risk that somebody with the computer name LB and username MARIK can connect to the database , even it is not a domain user?
