[Bug 89219] Switching back to an user account needs no password

[Manuel Hermann]

Public bug reported:

You can switch back to a logged in user account without entering the
password, if the user logged of using switch user.

Reproducable on 6.10:
1. Log in to an user account using GDM
2. Log out via switch user
3. Back in GDM hit <ctrl><alt><backspace> and you're in

This seems to work only once: You cannot switch the user, hit
<ctrl><alt><backspace>, switch the user and hit the three keys again.
Then you are asked for the password. To work again you have to log out
and log in again.

** Affects: gdm (Ubuntu)
     Importance: Undecided
         Status: Unconfirmed
