Public bug reported: Binary package hint: samba
I upgraded a Hardy installation to Intrepid, and I wanted to test Samba + Winbind authentication. I configured Samba, started the deamons, joined the domain and everything was working. wbinfo and getent show the proper information, however, roughly every 10 minutes winbindd will crash and will result in the trace listed at the bottom of this message. Winbind will keep on crashing until I run a "getent passwd" in a terminal, that somehow seems to fix it temporarily. Our domain controllers run Windows Server 2008 but the domain is still on 2003-mode. The schema has been extended with Microsoft's rfc2307 scheme and Winbind has been configured to use it. It is possible that this bug has been fixed in Samba 3.2.4, the release notes mention "Fix Winbind crash." ---- The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 13577 (/usr/sbin/winbindd). This means there was a problem with the program, such as a segfault. Below is a backtrace for this process generated with gdb, which shows the state of the program at the time the error occurred. The Samba log files may contain additional information about the problem. If the problem persists, you are encouraged to first install the samba-dbg package, which contains the debugging symbols for the Samba binaries.
