[Bug 1003308] Re: Live user is hidden in Lightdm, also "User Accounts" settings doesn't work in Ubuntu Live session (/etc/login.defs->UID_MIN should be set 999)

[Mantas Kriaučiūnas]

Lightdm login screen and "User Accounts" settings work correnctly in
Ubuntu Live session if /etc/login.defs has UID_MIN  999 :

ubuntu at ubuntu:~$ diff /rofs/etc/login.defs /etc/login.defs 
167c167
< UID_MIN			 1000
---
> UID_MIN			 999

Bug description:
  If user logs out in Live session then he can't login, because Live user is hidden in Lightdm login screen in Ubuntu Live session.
  Also "User Accounts" settings don't work in Ubuntu 12.04 when running from LiveUSB/LiveCD, it's always reproducible:
   - click on "User Account" icon in "System Settings" window and you  get "User Accounts" window with all widgets disabled - nothing happens when I click on "My Account" or "Other Accounts" at the left :( I'm attaching a screenshot of not working "User Accounts" window.
  This bug is very easy to fix -/etc/login.defs->UID_MIN should be set 999 in Live session, because casper script /scripts/casper-bottom/25adduser adds live user with uid=999 and Accounts Service daemon excludes users with uid lower than UID_MIN from /etc/login.defs (see daemon_local_user_is_excluded function in accountsservice sources)
  Please, improve /scripts/casper-bottom/25adduser script to set UID_MIN to 999 in /etc/login.defs file.
