samba - passwords MD5

[Joao Paulo Pagaime]

Hi all

I've just installed 3.2-RELEASE FreeBSD with MD5 passwords, but
it seems samba is unable to authenticate users on the machine:

smbclient //atlas/jpsp -d 5 -U jpsp
[ ...... lots of debug output ........ ]
Session setup failed for username=jpsp myname=OBERON destname=ATLAS
ERRSRV - ERRbadpw (Bad password - name/password pair in a Tree Connect or
Session Setup are invalid.)
You might find the -U, -W or -n options useful
Sometimes you have to use `-n USERNAME' (particularly with OS/2)
Some servers also insist on uppercase-only passwords

And the server says :

Jul  6 21:23:13 atlas smbd: no modules loaded for `samba' service

Does anyone have  samba-2.0.3  running with MD5 passwords ?
What's that 'module' samba is talking about ?

Any help at this point would be appreciated,
Joao Pagaime

but I'm stuck on this one...
