[Samba] Problem joining domain.

[Ray Van Dolson]

Hi all, I'm trying to join several RHEL 4.7 based machines (Samba
3.0.28) to our domain here.  I'm trying to do this via the net rpc
commands as this has typically worked fine in the past (iow: not doing
net ads join).

My smb.conf is as follows:

[global]
  workgroup = DOMAIN
  netbios name = RHEL47TEST
  security = DOMAIN
  log file = /var/log/samba/%m.log
  max log size = 500
  wins server = 10.1.1.1
  dns proxy = no
  log level = 10
  password server = *
  #username map = /etc/samba/username.map
  #log level = 0
  socket options = TCP_NODELAY

Pretty straightforward.

When I do the following however, I get:

# net rpc join -U Administrator -w DOMAIN -d 4

Now, normally I would expect this to mean there's a conflicting machine
already in the domain somewhere... but per our domain admins, there is
not.  

I've tried using other user accounts (although it doesn't even appear
to be getting far enough to matter) and specifying many options on the
command line (the server, ip, etc).

Any suggestions?  I'll be trying an older version of Samba from RHEL
4.6 as well as on other Linux boxes to make sure this isn't some sort
of regression, but maybe someone here can point me in the right
direction.

Thanks,

Ray
