the problem seems to be related only to pam_winbind not directly to lightdm. Also gdm does not allows the login. I attached a grep of syslog file kept after inserting username and password on gdm. Gdm hangs showing me "your password will expire in 12 days".
** Attachment added: "grep '12:04:09' syslog" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1003296/+attachment/3203411/+files/gdmcrash.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1003296 Title: lightdm crashed with SIGSEGV in _pam_winbind_change_pwd() when password is expiring Status in “lightdm” package in Ubuntu: New Bug description: My precise client is member of a Windows Domain. A domain user can login using samba/winbind without problem in tty and via lightdm if the user password is ok. If the password is expiring a domain user logs in correctly via TTY, with a message "Your password is expiring in 10 days". if tries with lightdm the user gets the message "Your password is expiring in 10 days", but then returns to the username request. On /var/log/syslog i get: May 23 08:50:52 tv52605 kernel: [ 1046.645230] lightdm[2415]: segfault at 0 ip b73d976a sp bfd66fa8 error 4 in libc-2.15.so[b729c000+19f000] for each time the user tries to login with the domain user credentials. Expected behaviour: the user sees the message "Your password is expiring in 10 days", then logs in (like gdm in ubuntu 10.04 does). I attach the crash file i found in /var/crash/ (that i'm unable to send via apport-bug tue to same strange bug) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1003296/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
