I am using fresh install of Xubuntu 14.04 and I have a slightliy different behaviour than what is described above:
1. create a user with uid = 60001 (e.g change uid for an existing user in extended settings from users-admin dialog) -> Result: The user is neither shown in the users-admin dialog, nor in lightdm-greeter, but can of course still log in manually. 2. in /etc/login.defs set UID_MAX=99999999 -> Result: the user *is* shown in users-admin dialog and after *reboot* the user also *reappears* in the lightdm-greeter - Note: a simple 'service lightdm restart' was not enough, I had to do a full reboot! So for me changing the UID_MAX in login.defs is a usable workaround, but it definitely should be documented, at least in the users-admin gui. Also a short note about the dropped users and a hint to the woraround (solution?) should be shown in the lightdm-logs. Warning: I don't know yet, whether this setting in login.defs has some other security implications. I just noticed that there is a couple of new setting files concerning id ranges for "subordinate user ids" (e.g. /etc/subuid), which use some "uids" in distances of 65535. Sadly even after searching for quite a while I still don't have a clue what they are for. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1290785 Title: Users with big UID are invisible in login and Settings->User To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1290785/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
