Use groups from LDAP (AD) in the definition of admins

Hello - 1st post, so apologies if I don't get the etiquette right.

Config is ejabberd 2.1.5 running on Ubuntu 10.04 32 bit, authenticating against a windows 2003 r2 active directory.

I have ldap auth working, I have also been able to identify one user as the ejabberd admin account and that works as well.

What I would really like to do (this is potentially a 10,000+ user install and we tend not permission individual accounts), is to have all the members of a particular AD group specified as admins of ejabberd - I have not seen any examples of this, nor is it documented as far as I can see.

So - while I continue searching, is it possible to specify the admin acl to be an ldap/ad group rather than a series of users?

Thanks
paul
