That last comment should be "There seems to be no good reason to
consider users with UID > UID_MAX are system accounts so the best
solution is probably to remove that check."

** Description changed:

- 13.10
- =====
- What I did:
- - Install 13.04
- - create user with UID 10203040 (works as expected on login screen and User settings panel)
- - update to 13.10
+ [Impact]
+ Users of Ubuntu 14.04 LTS with UID > 60000 will not show in the greeter or system settings without editing UID_MAX in /etc/login.defs. This was not required in 12.04 LTS. In 12.04 LTS users were only hidden if they had UID < UID_MIN. In 13.10 this was changed to UID < UID_MIN or UID > UID_MAX.
  
- Expected
- - User available on login screen
- - User shown in system-settings
+ [Test Case]
+ 1. Create a user with a UID > UID_MAX:
+ $ adduser --uid 60001 big-uid
+ 2. Restart system
+ Expected result:
+ "big-uid" is shown in the greeter. Once logged in "big-uid" is shown in system settings.
+ Observed result:
+ "big-uid" is not shown in the greeter (14.04 LTS, 14.10)
+ "big-uid" is not shown in system settings (13.10, 14.04LTS, 14.10)
  
- Actual
- - User _not_ available on login screen, login with manually typed username works
- - User _not_ shown in system-settings
- 
- What I did further
- - in /etc/login.defs set UID_MAX=99999999
- 
- Actual outcome
- - User _is_ available on login screen
- - User _not_ shown in system-settings
- 
- 14.04
- =====
- What I did:
- - update do 14.04
- 
- Expected
- - User available on login screen
- - User _still not_ shown in system-settings
- 
- Actual
- - User _not_ available on login screen, login with manually typed username works
- - User _still not_ shown in system-settings
- 
- So now with 14.04 it is fully broken.

+ This could cause users that were previously hidden to be shown. This seems unlikely to be a problem as all system created user accounts are less than UID_MIN and there doesn't seem be a convention to use accounts > UID_MAX for this case.

  Users of Ubuntu 14.04 LTS with UID > 60000 will not show in the greeter or system settings without editing UID_MAX in /etc/login.defs. This was not required in 12.04 LTS. In 12.04 LTS users were only hidden if they had UID < UID_MIN. In 13.10 this was changed to UID < UID_MIN or UID > UID_MAX.

  [Test Case]
  1. Create a user with a UID > UID_MAX:
  $ adduser --uid 60001 big-uid
  2. Restart system
  Expected result:
  "big-uid" is shown in the greeter. Once logged in "big-uid" is shown in system settings.
  Observed result:
  "big-uid" is not shown in the greeter (14.04 LTS, 14.10)
  "big-uid" is not shown in system settings (13.10, 14.04LTS, 14.10)
