I cannot reproduce this problem here. Changing the password, and then trying to use this in a new shell does work here. (Note that you have to open the shell you try in after you close userconfig, otherwise PAM's caching apparently still has the old password.
Setting the USER ID had been discussed earlier, but we're not planning to implement this right now. (Patches welcome, if done well.) ** Changed in: kde-guidance (Ubuntu) Status: Unconfirmed => Rejected -- kubuntu system settings reset User ID https://launchpad.net/bugs/46114 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
