Better to catch these before release I guess:

#9  0x080841a5 in winbindd_dual_pam_auth_crap (domain=0x828e260,
state=0xbfd3d1f4) at nsswitch/winbindd_pam.c:637
637      result = rpccli_netlogon_sam_network_logon(netlogon_pipe,

(gdb) print netlogon_pipe
$3 = (struct rpc_pipe_client *) 0xe


What happened is that I have a Samba member server
joined to a Samba domain.  I rebuild, re4installed,
and restarted 3.0.21b on the PDC.  Therefore teh connection
from the member server is invalid.  Hence the bad pointer.
