X-Comment: Discussion of NT domain controller support in Samba

All,

I've been banging my head against this problem for several days now, and
although I've gotten file and printing services working rather well against
the SAMBA_TNG PDC, I haven't been able to join any workstations, Samba or NT,
to the domain.  Of course, the PDC functionality was the whole reason for
switching to TNG, so this kinda puts a damper on things. :)  I've tried using
samedit to join a domain:

# samedit -S . -U root -N
added interface ip=xx.xx.xx.xx bcast=xx.xx.xx.255 nmask=255.255.255.0
[root at .]$ use \\\\<PDC> -U root
use \\\\<PDC> -U root
Enter Password:
Server: \\<PDC>:        User:   root    Domain:
Connection:     session setup ok
Domain=[DOMAIN] OS=[Unix] Server=[Samba TNG-alpha]
OK
[root at .]$ createuser sheridan$ -j DOMAIN
createuser sheridan$ -j DOMAIN
SAM Create Domain User
Domain: DOMAIN Name: sheridan$ ACB: [W          ]
Create Domain User: FAILED
[root at .]$ 

This gives me a new user in the private/smbpasswd file, with no password set.

sheridan$:90210:NO PASSWORDXXXXXXXXXXXXXXXXXXXXX:NO PASSWORDXXXXXXXXXXXXXXXXXXXXX:[NDW        ]:LCT-FFFFFFFF:


In /var/log/samba/log.samr, I then see the following lines (-d 0):

The interesting line here seems to be the decode_pw_buffer error, but I don't
know what it means.  I'll gladly provide logs at higher debug settings if it
will help, I just don't know what I should be logging at this point.

I also tried checking out a copy of the CVS tree from 10 days ago and also
from a month ago, and I found the same problem.  So either I'm doing something
seriously wrong when trying to join the domain, or this bug's been around for
a bit already. :)

Incidentally, I can still join the domain using smbpasswd -- sort of.  The
smbpasswd entry seems to be updated correctly, but if I try to connect to the
workstation using domain authentication, I get more errors..

Does this error message suggest an obvious mistake on my part, or am I looking
at a bug in TNG?

TIA,
