[Samba] NT4 Domain Member Server Access Denied v3.07

I want to set up a Samba Server (Cactus_3) as member server in our NT4 
domain (PDC is Cactus_1, BDC is Cactus_2). We have about 50 client 
workstations most of which are WinXP but we have a few Win2K and Win98 
machines.  Shortly we will migrate off the NT4 servers but in the 
meantime we wish to test some real time scenarios.  It is for this 
reason that I want SSO so the tests are transparant to the users.  I 
don't want to replicate 40 users into the unix environment.  I followed 
the setup in Chapter 2 of the HOWTO Collection for a Domain Member server.

I am using Samba 3.07 on Suse 9.1. My smb.conf file follows the 
signature line as well as nsswitch.conf file.

I have reread chapters 3,6, & 9 from the HOW-TO Collection.  I have read 
through the archives for October & September and googled the user group, 
but i am still not finding what I am missing.  Here is an outline of 
whats happening.

1) "linux~# net rpc join -U<domainadmin>%<password>" works, at least it 
responds with 'Joined domain DOMAIN'.

2) "linux~# wbinfo --set-auth-user=,<domainadmin>%<password>" appears to 

3) "linux~# wbinfo -u" succeeds in giving a list of all domain users 
(same for groups with -g flag) however it shows "domainuser" only and 
not "DOMAIN+domainuser" as indicated in the chapter text.

4) "linux~# getent passwd <domainuser>" succeeds.

5) "linux~# chown <domainuser> /export/a_file" appears to succeed 
however a listing of "/export/a_file" shows owner remaining as 'root'.

6) "linux~# net rpc trustdom list" fails with the message:
linux:~ # net rpc trustdom list
Could not connect to server CACTUS_1
The username or password was not correct.
[2004/10/06 16:31:06, 0] utils/net_rpc.c:rpc_trustdom_list(3030)
  Couldn't connect to domain controller
linux:~ #

7) Other 'net rpc' commands fail as illustrated:
linux:~ # net rpc samdump
[2004/10/06 16:36:41, 0] utils/net_rpc_samsync.c:rpc_samdump_internals(216)
  Could not fetch trust account password
linux:~ # net rpc getsid
Storing SID S-1-5-21-1930001043-1750228388-9522986 for Domain DOMAIN in 
linux:~ # net rpc vampire
Could not retrieve domain trust secret

8) From Windows Explorer on a Windows PC workstation I see the Samba 
server (Cactus_3) and I see shares (ACCTMATE, DOCUMENTS, PICTURES, 
Printer LexMark T522) but I get 'Permission Denied' when attempting to 
access.  Mapping through "net use k: \\cactus_3\documents" succeeds but 
access is still denied. A directory listing from the command window 
responds as "File not found."

Please be so kind as to point out what I am missing.  Thank you for your 
kind help.
