Ldap authentication with groups

I have been searching but can’'t find an exact answer to this.

I currently have wildfire authenticating against my entire active directory and it works fine. i want to be able to select a particular group to allow to authenticate. Basically i want to create a group, lets say we call it “Wildfire Users”

I only want members of “Wildfire Users” to be able to authenticate and login.

Does anyone know how to do this?

Sure, that’'s easy. User a search filter similar to this:

(&(objectCategory=Person)(memberOf=CN=Wildfire Users,OU=Groups,DC=example,DC=com)(sAMAccountName=))
