Description Christian González 2009-03-06 21:29:13 UTC 
Version:            (using KDE 4.2.1)
OS:                Linux
Installed from:    Ubuntu Packages

go to KDE systemsettings ->Login Manager ->Users
You can specify which users are shown, and which not: which are "system users" and which not.
defaults are "below 1000" and "above 29999".
That's a problem, because 29999 is the maximum that this KDE systemsettings module allows:
e.g. group-e (http://www.group-e.info), a Groupware Suite which we have running here, creates users with UIDs beginning with 3000001.

See the problem?

I can't tell KDM to show all users from 3000000 to e.g. 3999999 - because this module prevents this - So I can't use KDE for showing all these LDAP users in KDM.
The highest possible group in Linux is 2147483647, so this should be an easy fix.

It seems that the values are hardcoded (not sure why):

It seems that the limits can be removed. I hope KDM people look into this, otherwise I will post a patch.

Whow, that was a quick fix.
I also think that the usability could easily be improved, but I reportet that as another bug (wish): Bug #186430
