[Bug 1064584] Re: Locked gnome session unlocks without password authentication

[Brian Murray]

** Description changed:

- When switching between users in ubuntu 12.10 using gdm a rather
- unpleasant behaviour can occur when a locked session unlocks without
- password authentication.
+ [Impact]
+ When switching between users in ubuntu 12.10 using gdm a rather unpleasant behaviour can occur when a locked session unlocks without password authentication.
  
+ [Test Case]
  Steps to reproduce:
  1. Login as user1 (password required)
  2. Lock screen
  3. Select login as other user
  4. Login in user2 which does not require any password, e.g. guest
  5. Logout user2
  6. Screen returns to unlocked session for user1
  
  It doesn't happen every time but rather frequently so I suspect some
  sort of race involved.
