package : kdebase version : 1.1.1-19990717 I have a debian potato with full nis+ client installation (nisutils 1.1 , pam-keylogin 1.2). The kde screenlockers seems not able to use nis+ map to check for the password (even with suid). xlock is working fine with nis+ I suggest to at xlock code to get a workaround.
