[Samba] Samba question

[Curtis, Brian E CTR USAF ACC 82 CSS/SCOA]

All,

     I'm trying to find out if you can limit Samba to only pull user accounts from a particular Active Directory OU.  My AD has over 200K contacts entries for the global address list so I would like samba to only query the location with the valid user accounts.  I'm running samba 3.0.1.

Thanks for any help/suggestions you can provide,
Brian
