I've read the docs. I've bought the book. I've searched the lists. For
three days and still no joy. Please help. Here are the details:
OS: Redhat 9.0 on a Dell Poweredge 2650
Using stable samba 3.0 rpm downloaded straight from the site
Configuring by any means necessary: webmin, swat, but right now, smb.conf
I have set up a linux account for smbuser, added him to ntadmins group,
net group mapped ntadmins to "Administrators", added the XP patch to set
RequireSignOrSeal to 0, set the smbpasswd, enabled the smbpasswd account,
restarted smb services, set up a NetLogon and Profiles share (with no
logon script to make things easier), created a home directory for smbuser
and such, added a machine account for the machine I am trying to connect
from (alpha), created the linux user for that (alpha$), and then tried to
add the XP computer (alpha) to the domain (TEC). It asks for username
and passwd. I supply both for smbuser. It says "Access is denied".
Next step. I turned up the logging level to 3 (2 didn't give anything
useful). Here is the log:
[2003/10/29 16:46:03, 2] auth/auth.c:check_ntlm_password(302)

This was before I added smbuser to the ntadmins group. Now after:

Upon trying a manual net join from the server, with "net join pdc -U
smbuser" I get:
Create of workstation account failed
Unable to join domain TEC.
Possibly this could be because the server itself doesn't have a samba
machine account??
And finally, here's my smb.conf:
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command
"testparm"
# to check that you have not made any basic syntactic errors.

# All NetBIOS names must be resolved to IP Addresses
# 'Name Resolve Order' allows the named resolution mechanism to be
specified

unix
# system gethostbyname() function call that will use either /etc/hosts OR
# DNS or NIS depending on the settings of /etc/host.config,
/etc/nsswitch.conf
# and the /etc/resolv.conf file. "host" therefore is system configuration
# dependant. This parameter is most often of use to prevent DNS lookups
# in order to resolve NetBIOS names to IP Addresses. Use with care!
# The example below excludes use of name resolution for machines that are
NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.

NOT both
; wins server = w.x.y.z
# WINS Proxy - Tells Samba to answer name resolution queries on
# behalf of a non WINS capable client, for this to work there must be
# at least one WINS Server on the network. The default is NO.
; wins proxy = yes
# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups. The built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.

# Case Preservation can be handy - system default is _no_
# NOTE: These can be set on a per share basis

# Default case is normally upper case for all DOS files
; default case = lower
# Be very careful with case sensitivity - it can break things!

Please help. I've exhausted my resources. I'm never one to post to
lists--I always find my answer online--but this one has me stumped. I
can't even figure out how to diagnose the problem, so please: I need
suggestions. I need to have this network running by tomorrow at the
latest. I've set up samba networks before, but this one is being a royal
pain.
Thanks in advance,
