I doubt that the username and/or password is the problem as an ORA-12638 is generated before the username/password pair is checked. Since I don't know what O/S or Oracle version you are running, it's difficult to determine what is going on (it doesn't help that a 12638 is a generic error).

Take a look at your sqlnet.ora file. If it has an entry like: sqlnet.authenticaton_services=(.....)
Change it to be
sqlnet.authentication_services=(NONE)

and try the connection again.

It is probable that the connection is trying to use the Advanced Security Option and ASO has not been set up.
