Login without password in KDM


Hi,

I actually am a Debian user, but I wanted to try a 'simpler' distro. Everything went fine, but there are a few problems. One of those is:

I can't allow users to login without a password. I have multiple users working on my computer, and I don't mind typing a password, but they do. I tried the SUSE configuration option "Password-less login", but this has no effect (and it actually does not do what I want; I'd like to be able to define password-less logins per-user). Configuring KDM via the KDE Control Center has neither. What is the problem here? Does the SUSE Configuration override the default KDE configuration? (Even then, the SUSE configuration doesn't help.)

Any help would be appreciated; it may help me to definitively switch to SUSE

-Frank

(SUSE 10.0)

P.S. This is almost the same message as the previous one, but this time another problem; I wanted to separate the problems in 2 different threads

It seems there are 2 kdmrc files on my system.
Which one is actually used? It seems the 1st one is used by the KDE Control Center.

Which one is used depends on the configuration of the install. It might use both. Before going any further I would do this. I would rename one of the kdmrc to say kdmrc_backup. Restart X and see if the login gui is different or not running. If it looks okay then go back to the locaton you rename the kdmrc file and make sure there is not a new kdmrc file. If not then the other location is the one we should start working with. Sometimes there is a symbolic link to kdmrc in /X11/xdm.

Got to go, trick or treaters here.
