LDAP result limited to user group

Hi Folks. 1st, please reply to me directly as well on le@mmc.school.nz I've set up our LDAP server as per the guide in AFP Question, how can I restrict the list for our students to just users in the Group "Students" I've placed in address book "cn=users,dn=NameServer" This returns all users, both students and Staff This is okay for the staff, but I want the students to only get the students, NOT the staff. Thanks. Kent Lendrum HOD Computers Mount Maunganui College New Zealand.
