How Thruk can use AD groups to distinguish admin/normal users?

Hello all,
I use thruk 2.32-3 with Apache 2.4 integrated with LDAP/SSO authentication.
What I would like to do is to distinguish Admin users and normal users.
For this reason we have defined 2 different AD group, but I dont find how to configuring in cgi.cfg, I tried to define in:
authorized_for_admin=Nagios_Admins
but it doesn’t worked.
Could you povide any suggestions please?
thanks
Antonio

It works
