"This does not work at the moment - users have to be direct members of groups defined in ‘auth_ad_groups’ parameter (placing a group there does not do anything)
Generally, “MATCHING_RULE_IN_CHAIN” filter should be used to get nested group membership for the user, but this does not work with LibreNMS at the moment. The syntax could be looking a bit like this:
$config[‘auth_ad_group_filter’] = “(member:1.2.840.113556.1.4.1941:=$username)”"
