smbpasswd seg faults

[Alan Hourihane]

I working with a current cvs tree of 2.1, and
smbpasswd seg faults with....

cli_connet_serverlist: Domain password server not available
Segmentation fault.

I've backtraced it with gdb and in utils/smbpasswd.c we 
initialize the pwdb with is_server set to False, so then it
looks for a 'password server' entry which I don't have one
as all the authentication is done on this machine.

I've set the is_server to True and now it runs but now it
can't find user entries in the smbpasswd file, yet the
old 2.0.5 smbpasswd works on this machine.
