samba - Jan 2006 - pdb_init_sam failed?!

Hi all,

This afternoon my Samba server started rejecting everyone's passwords,
with the error "pdb_init_sam failed!"  What does that mean?  I've
never
seen the error before.  It seems that the password is being checked
correctly with Active Directory, as an incorrect password yields a
different error message, but the pdb_init_sam seems to cause Samba to
reject even a correct password!

Any ideas what this message is for?

Thanks,
Adam.

How bizarre, I got a chance to kill off and restart smbd, and now it
works fine...
