Steve, Yes, moving or not moving the directory doesn't make a difference, it will segfault in both cases. Recreating the directory as Thierry suggested does fix the problem, though.

What's the basis for claiming that there's a corruption problem? I haven't seen tdb corruption in samba for many years. The backtrace in this bug isn't a corruption issue at all; the get_global_sam_sid() call panics if called by a process that can't create or read /var/lib/samba/secrets.tdb. The trick is that libpam-smbpass isn't supposed to call get_global_sam_sid() - so something has changed here. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

Thierry Carrez wrote: By corruption I didn't mean a corrupted bits in a specific file, but rather a corrupted state for the global /var/lib/samba directory contents... The basis for this is that in the mentionned bugs clearing the directory (and especially the existing secrets.tdb file) made everything working again. Clearly the backtrace analysis is more precise than this wild guess based on observed symptoms.

Thierry Carrez wrote: Jorrit: it will indeed segfault if there is no /var/lib/samba directory anymore. But an existing (empty) /var/lib/samba should work (files will be recreated). That is, if this bug is the same as the other two I mentionned. Thierry, I guess you are right.
