Description Nathan Toone 2003-12-16 00:21:24 UTC

Version:            (using KDE KDE 3.1.94)
Installed from:    SuSE RPMs

When set to automatically log in, I get an error dialog:

"Authenticating <username>..."
"Authentication failed."

When starting kdm in debug mode (with -debug 1), I get the following messages in my syslog:

This was working before I upgraded to the 3.2 beta - so I don't believe it is a PAM configuration issue.  The only chnage made was upgrading to the 3.2 beta.

i bet 10:1 that this is the same problem ...

Comment 2 Nathan Toone 2003-12-16 00:42:36 UTC

Worked great - it appears that SuSE doesn't include the new pam mechanisms either.  I just created a file /etc/pam.d/xdm-np (it was using xdm-np - not kdm-np) with the contents:

auth required /lib/security/pam_permit.so

Thanks for helping track that down!

I wanted to let the powers that be know that I had this exact same problem with the Debian dist of 3.2 and was able to resolve using the method described by Nathan.  Thanks!

i've also got this problem in Kubuntu with kde 4.0.4

can't get any sort of auto-login going on
