[Samba] smbd PANIC starting PAM

[Robert W. Smith]

Happened to be tail'ing <machine>.log during a login session from XP
client and notice the PANIC in the output. Login proceeded as usual(?)
so the following snippet of the log is just informational to the
developers. Let me know if you need additional info.
