stor2rrd MS AD authorization and permissions

Hi,

I have set MS AD authorization for stor2rrd access via mod_auth_kerb module in httpd.conf, it works alright. Now I need to restrict configuration permissions in order to make it possible to configure SAN storage resources only for particular AD group or to a list of AD users (not local httpd-defined users). Is it possible to do it in stor2rrd? Configuration manual on the website gives only information about local users, defined in httpd.conf.
