in the process of merging some of the radius modules, i started to wonder if anyone is really using group_radius module that provides a single function radius_is_user_in(). if i remember correctly, the module was originally written by jan to complement db based group module.
i personally don't use group module, because it is more efficient to return caller's or callee's groups as reply items from authentication or radius_does_uri_exist calls.
please reply to this if you use group_radius module. if no positive replies arrive, perhaps we can delete the module altogether.
