LDAP - Restricting login to certain members

I’'ve been working on using LDAP to authenticate users within wildfire.

Right now every user in the LDAP database can login.

I want to restrict this so that only users who are members of a certain group can login.

Is there a way to do this? If so, how? Examples?



I assume that you need to use a filter and that this was already discussed. It may help if you post some structural information of your LDAP setup and which groups/users should be allowed to login
