Summary:                    login gives information on user existence
Description: 
If a non existing user is entered at the login prompt, it will return an
error, istead of asking for the password as the standard login does. This
gives information to a potential attacker about the existence of given
user in the system.

No big deal but certainly a security leak easily fixable.
