[Samba] Unable to use 'valid users' from Active Directory

It would act as if it's not seeing the credentials for the share that is
using the group specification.

So to summarize what going on:

The public share prompts for a username and password but does not take

   comment = Public Stuff
   path = /home/
   public = yes
   read only = no
   valid users = @"_IFAS-FRE-USERS_autoGS"

A share that does not have the user requirement allows a Active
Direcotry user to login just fine.

   comment = %U Home Directory
   browseable = no
   path = %H
   valid users = %U
   writable = yes
   create mode = 0664
   directory mode = 0775

OH, okay, I thought you *wanted* it to prompt for a username.  In that
case you'll only get a prompt if the credentials you're already using
are incorrect, i.e. you correctly logged into the domain, then you
connect to Samba and pass those same credentials on, Samba rejects the
credentials for whatever reason and then you get a prompt asking for a
valid username and password.

Which computer name is that?  If it's the Samba machine, it would
indicate that it hasn't correctly joined the domain.  Part of the
process of joining a domain involves creating a computer account in
Active Directory, which is the account Samba uses when it connects to
the directory to retrieve a list of users/groups.

Almost none of the domain config is stored in smb.conf, it's all updated
dynamically in the binary data files when you run commands like 'net
join'.  You'll need to run things like "net testjoin" etc. to try to
figure out why wbinfo is working but smbd isn't.
