Thanks, Ray ! So it's fixed upstream in 3.4.3 / 3.3.9, which confirms John's experience. we should push this to the next Samba SRU. ** Changed in: samba (Ubuntu Karmic) Importance: Undecided = Medium -- winbind crashes on authentication (winbind_pam_auth) https://bugs.launchpad.net/bugs/503402 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 503402] Re: winbind crashes on authentication (winbind_pam_auth)
I was attempting to track this down for RHEL5 (see here[1]). When I apply the patch generated by this commit[2], I can no longer reproduce the winbind segfault. This is against RHEL5's 3.3.8 and, I would assume, would be appropriate for Ubuntu's 3.3.x version as well.

Thanks for the pointers, it's very useful. I'd try the first one first, it seems closer to what you experience.

Re: [Bug 503402] Re: winbind crashes on authentication (winbind_pam_auth)
@Thierry: I don't know if it's helpful, but I took a look at the release notes for the later versions of samba and found three fixes that roughly relate to the same module, at least: (3.4.3) * BUG 6793 https://bugzilla.samba.org/show_bug.cgi?id=6793 : Fix segfault in winbindd_pam_auth. * BUG 6811 https://bugzilla.samba.org/show_bug.cgi?id=6811 : Fix reference to freed memory in pam_winbind. * BUG 6840 https://bugzilla.samba.org/show_bug.cgi?id=6840 : Fix crash in pam_winbind. Perhaps you've already disqualified them; I don't know enough about the codebase to confirm one way or the other.
