I'm not sure if I am just being stupid and misunderstanding the Moodle documentation but I have LDAP enrolment working fine except...

How can I get an LDAP group in both the teacher and the student enrolment OUs at the same time? AD won't let me create 2 groups with the same name and they need to have to same name to map to the same course ID right? At the moment I'm just using it to enrol students because I can't create another group for the teachers. Hopefully someone who has done this knows where I am going wrong. Thanks.
