Hi Rowland,

Thanks for the quick response.   My response is inline below...

I like the command line, thanks for the option.   For this particular 
install I used 'ldbedit -e vim -H /var/lib/samba/private/sam.ldb'.    As 
it turns out, the GID was in place just fine, but for some reason the 
Windows tool is throwing that error.

Excellent,  I think I'm in business now.

passwd: compat winbind
group:  compat winbind

smb.conf additions to make the ADC also an AD-Client:
# sercurity=ads  # Mutually exclusive with server role = a.d.d.c!
idmap config MY_DOMAIN : backend = ad
idmap config MY_DOMAIN : range = 10000 - 99999
template shell = /bin/bash
template homedir = /home/%U
winbind refresh tickets = yes
winbind trusted domains only = no
winbind use default domain = yes
winbind enum users = yes
winbind enum groups = yes
winbind nss info = rfc2307
Look good? Any suggestions?

Unrelated : A couple of un-intuitive things in order to get a logon 
script to work with an ADC:
1. Use ADUC to add logon script name like normal.  This however has to 
be a relative path (logon.cmd not \\DC\netlogon\logon.cmd)
2. Set the +x bit in unix on the script

Thanks again for your help and of course for Samba.
