Please read the release notes.  multiple passdb backends 
are no longer supported.  In addition, the guest backend 
was never documented to be included in smb.conf.  Just set

   passdb backend = tdbsam

I'd like to add that a segmentation fault is probably a suboptimal way to react to an invalid configuration file setting.  It should just terminate normally after "failed to get pdb methods" or whatever.

It's not a seg fault.  It's a forced panic (similar to as 
assert() firing).
Comment 8 Gerald (Jerry) Carter 2006-08-22 11:18:55 UTC
no response.  Pretty sure this is just a config error.
Comment 9 peter green 2006-11-08 21:14:01 UTC
>multiple passdb backends are no longer supported.
so why doesn't the panic say that rather than a cryptic "failed to get pdb methods for backend tdbsam guest"
