Hello jjongman

In parameter file OS authentication the symbol i used is OPS$ as in Production and made the Remote_login_password as None and created the user with this authentication and made the user as External and given the proper privileges.When i tried to login with OS authentication as '/' followed by connecting string it says that invalid username and password.
ERROR:
ORA-01017: invalid username/password; logon denied
But the user with password able to login.
Now u understand what i mean
