[Samba] Errors encountered joining Active Directory domain

[Bruce Alge]

I am using Debian Sarge with samba 3.0.20b-2 installed. I have a Windows 
server 2003 with Active Directory installed. The window's machine name 
is server2knew.ENTERPRISE.CXM. I can connect and log into the domain 
from a WinXP client. I used the smb.conf file and nsswitch.conf file as 
listed in the Samba3 by Example (Chapter 7).

testparm appears ok except for the line that reads:

template primary group = "Domain Users" is missing from the output

I then ran the command:

root:/# net ads join -U Administrator%<password>

this returned the following output:

[2005/11/17 22:46:52, 0] param/loadparm.c:map_parameter(2544)
  Unknown parameter encountered: "template primary group"
[2005/11/17 22:46:52, 0] param/loadparm.c:lp_do_parameter(3285)
  Ignoring unknown parameter "template primary group"

[2005/11/17 22:46:53, 0] utils/net_ads.c:ads_startup(191)

I appreciate any help with this problem.
