Bug 196187

Hello Sven,

I was not able to reproduce that problem by (unsetting) the password with `passwd' for a local user. Without any change to KDM it allowed me to log in without a password. Maby this is a problem specific to YaST.

Please attach /var/log/YaST2 as tarball here. Also try if changing the password manually (with `passwd') works for you.

Passwordless login does not mean that you do not have a password. It means that you can login without entering your password, i.e. by double-clicking your account in kdm.

Setting the password to empty is a workaround.

This might work if you do the following:
Say this is your fstab line:

micha:x:32001:100::/home/micha:/bin/bash

Then simply remove the :x: like:

micha::32001:100::/home/micha:/bin/bash

This should lead the login process to not check/ask for a password because it knows there is none. Does it work that way?

fstab is for mounting-points is it not? This issue is just about logging into KDE via kdm. It is not about logging in on any console.

For kdm to let the user login, /etc/opt/kde3/share/config/kdm/kdmrc has to be altered and it is but not enough.

If I check the "allow passwordless login" in YaST /etc/opt/kde3/share/config/kdm/kdmrc.SuSEconfig is altered, so this setting is meant to affect kdm.

In the [X-:0-Core] section NoPassEnable is set to true/false depending on the YaST-setting. Yet that is not enough because there is an empty string for NoPassUsers. Hence, for display 0 no user is allowed to login without entering the password. For display 1,2... it works because the [X-:*-Core] section does not contain any empty strings.

To make kdm work the intended way, YaST has to offer a checkbox in the user's settings that adds his/her username to the NoPassUsers-stings in kdmrc.SuSEconfig. And YaST must not set any empty strings for [X-:0-Core], since those override the settings for [X-:*-Core].

It seems unlikely that a user enables passwordless login for kdm, but wants that no user is allowed to do so.

Maybe some kde-maintainer can help resolve this issue better than I can.

I ment the /etc/passwd of course.
Please try that first. If it does not work, I'll reassign.

OK this does not appear to work.
I'm reassigning this to the KDE maintainers for a comment.

sounds likely. Not sure when I tested this the last time

i have the same problem - I tried to use this from suse 9.3 http://en.opensuse.org/SDB:Change_Behavior_of_KDE_Login_Manager_(KDM)

but it doesnt seam to work . I tried to edit /etc/opt/kde3/share/config/kdm/kdmrc
and it's all ok but doubleclieck login just doesnt work. 

Michael Gross it's not about deleting the password in linux, it's about allowing to login to kde without beeing asked for password.
Imagine i have a desktop with proftpd and sshd . I can't just erase my passwords because anybody would just login to my computer. I just want to have a possiblity to login to my kde withuot typing my passowd. 

It worked in my previouse distros so it has to be kde>3.5 related or suse related but having read http://en.opensuse.org/SDB:Change_Behavior_of_KDE_Login_Manager_(KDM) i think it's suse-related

ok i found the problem
tak a look at /etc/opt/kde3/share/config/kdm/kdmrc

the section that is changed when You change the options in kcontrol (the ones for passwordless login) is this
[X-:*-Core]

and here the options are correct
NoPassEnable=true
NoPassUsers=me,you

but bellow theres another sections that 'covers' it again

[X-:0-Core]

and its NoPassEnable and NoPassUsers are not changed when You change the options in kcontrol

so just put Your options  in [X-:0-Core] and everything will work ok

please vote http://bugs.kde.org/show_bug.cgi?id=131634

This is an SuSE issue, so voting at KDE will not really help. The solution is already part of comment #1, yet YaST has to make these settings and allow to chose the users to be added.

this should be fixed with latest updates (to factory and BS)
