no login possible after installing kubuntu-desktop

[HB]

I installed kubuntu-desktop, choose kdm as default window manager. after installing i am not able to login as the "primary" user neither using kdm nor using gdm. after trying to log in i find in auth.log:

Aug 23 23:30:32 holle-laptop kdm: :0[5186]: pam_unix(kdm:auth): authentication failure; logname= uid=0 euid=0 tty=:0 ruser= rhost= user=holle

I had to create a second user in order to be able to log in.

I'm using hardy, all packages up-to-date.

p.s. to avoid misunderstandings: login to gnome from gdm worked fine before i installed kubuntu-desktop.

I don't know why this bug was reassigned to pam; this looks like an error in setting up the user account with the requested password, not a bug in pam for failing to authenticate the user. As the submitter notes, setting up a second user and logging in with that account works fine, it's only the initial user that fails. So this is not an error in the PAM authentication process.

Reassigning back to kubuntu-desktop.

Is this reproducible in any way?

[HB (hbemail)]

no, because at the moment i'm running opensuse.

Closing then.

I'm affected by this bug after upgrading Kubuntu Oneiric to Precise by changing every "oneiric" occurrence to "precise" in sources.list and then running a dist-upgrade (because my environment was not triggering an available upgrade notification).

Something weird has happened in PAM, since it's trying to look for my user with a wrong uid.

I can login with "startx /usr/bin/startkde" only, but then I would get authentication failures everywhere I'm asked to input my password for root privileges, unless I run the same commands from terminal with sudo.

I wrote in the Kubuntu forums: http://www.kubuntuforums.net/showthread.php?58623-Can-t-login-via-KDM-after-upgrading-to-Precise

German forum with same problem: http://forum.ubuntuusers.de/topic/kein-login-in-kdm-nach-upgrade/#post-4316707

Please, tell me if you need more information.

I thought this might be related: I can run "sudo" without any problem, but "su -" is failing.

$ su -
Password:
su: Autenticazione non riuscita
$ sudo uname -r
[sudo] password for montblanc:
3.2.0-24-generic-pae

I'm sorry, I forgot I'm on Ubuntu which uses "sudo -s", my fault. Please, disregard the comment above.

The only thing that might help is that a newly created user can log in (password is accepted), but after trying to load X, it pops back to the login screen.
