Authenticating users on LDAP based on Group name

I have setup the group in groupmembership_attribute as a naive intent to
accomplish my goal.  If that is not the correct parameter I will really
appreciate your help on where I should set my Group and the syntax.

On my first email I included my LDAP.conf file as generated by pfsense.

I think is closed as needed because I was successful matching user/pass
with AD when group membership_attribute is default, but for all Users.  Now
I need to change it to consider the Group.

For now I only need to identify only one Group.  I am using FreeRadius for
a Squid proxy server then the User is used on Dansguardian.
