Hello again ;-) after hours of googling I'm non the wiser where the problem lies. When a user logs in on a client, the login keyring does not get automatically unlocked. It works fine when the same user logs in on the LTSP server itself. I tried different flavours of fat-client-desktop (ubuntu-desktop, lxde, kde-desktop, etc.) and also a different newly installed server.
The keyring password is the same as the login password, the login keyring is set as default in seahorse and libpam-gnome-keyring is installed by default. root@ltsp:/opt/ltsp/lxde/etc/pam.d# ls -la total 96 drwxr-xr-x 2 root root 4096 Apr 26 15:10 . drwxr-xr-x 97 root root 4096 Apr 26 17:04 .. -rw-rw-r-- 1 root root 197 Jun 25 2011 atd -rw-r--r-- 1 root root 384 Apr 9 2012 chfn -rw-r--r-- 1 root root 92 Apr 9 2012 chpasswd -rw-r--r-- 1 root root 581 Apr 9 2012 chsh -rw-r--r-- 1 root root 1208 Apr 26 15:07 common-account -rw-r--r-- 1 root root 1249 Apr 26 15:07 common-auth -rw-r--r-- 1 root root 1480 Apr 26 15:07 common-password -rw-r--r-- 1 root root 1482 Apr 26 15:07 common-session -rw-r--r-- 1 root root 1435 Apr 26 15:07 common-session-noninteractive -rw-r--r-- 1 root root 527 Apr 2 2012 cron -rw-r--r-- 1 root root 4585 Apr 9 2012 login -rw-r--r-- 1 root root 688 Apr 26 18:04 lxdm -rw-r--r-- 1 root root 92 Apr 9 2012 newusers -rw-r--r-- 1 root root 520 Feb 9 2012 other -rw-r--r-- 1 root root 92 Apr 9 2012 passwd -rw-r--r-- 1 root root 255 May 17 2012 polkit-1 -rw-r--r-- 1 root root 168 Feb 4 2011 ppp -rw-r--r-- 1 root root 84 Jun 8 2012 samba -rw-r--r-- 1 root root 2305 Apr 9 2012 su -rw-r--r-- 1 root root 239 Feb 27 20:32 sudo -rw-r--r-- 1 root root 108 Jan 30 2012 xscreensaver root@ltsp:/opt/ltsp/lxde/etc/pam.d# cat lxdm #%PAM-1.0 auth requisite pam_nologin.so auth required pam_env.so readenv=1 auth required pam_env.so readenv=1 envfile=/etc/default/locale auth sufficient pam_succeed_if.so user ingroup nopasswdlogin @include common-auth auth optional pam_gnome_keyring.so @include common-account session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so close session required pam_limits.so @include common-session-noninteractive session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so open session optional pam_gnome_keyring.so auto_start @include common-password How can I solve this problem? Please no suggestion like setting a blank password for the keyring, which is the accepted answer in so many web forums...
