Comment 7 for bug 459199

possibly the best way to fix this regression is, as suggested by Milan in #247910, to utilize the UID_MIN setting in /etc/login.defs. another way would be to use the gdm MinimalUID setting which I believe is what was used prior to Karmic. However, seems it would make more sense for consistency to use /etc/login.defs since that is what for ex. is used in "users and groups". since this is a clear regression from jaunty i have to say that i'm a bit surprised by the priority being set to low.
