+++ This bug was initially created as a clone of Bug #646056 +++ IT is also reproducible on F14. Description of problem: If your Active Directory password is about to expire, winbind passes that information into PAM - and gdm login attempts misread it as some form of failure - and you get bounced back to the login prompt Steps to Reproduce: 1. have account about to expire, so that AD starts nagging you to change your password 2. try logging in via gdm 3. see "your password is about to expire..." message in gdm window for a few seconds before it rejects your valid login attempt Actual results: can't log in. Expected results: valid password, should be logged in
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
I'm also currently running into this bug. As a workaround, I have been logging in on a console to change my password. Below is a snip of the stack trace in the GDM logs when a user tries to log in while their password is in the expiry period. Specifically, it looks like GDM is failing when it receives the message via PAM that the password will expire soon. pam: gdm-password[10906]: pam_winbind(gdm-password:auth): user 'user1' granted access ** ERROR:gdm-session-worker.c:817:gdm_session_worker_process_pam_message: code should not be reached gdm[10907]: ******************* START ********************************** gdm[10907]: [Thread debugging using libthread_db enabled] gdm[10907]: 0x0018e416 in __kernel_vsyscall () gdm[10907]: #0 0x0018e416 in __kernel_vsyscall () gdm[10907]: #1 0x4533af63 in __waitpid_nocancel () from /lib/libpthread.so.0 gdm[10907]: #2 0x0805568d in ??

Sorry for the double comment. I forgot to mention that I'm still experiencing this bug in Fedora 15, with all current patches applied. Also, console login works without a hitch (with the password expiry message displayed).
Updated version to 16. Confirmed still happening
workaround is to put "warn_pwd_expire = 1" in /etc/security/pam_winbind.conf file.
I've also experienced this problem (as recently as today). I'm on F16. I'll try the workaround.
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
