Hi Till, I've been following your server configurations here at howtoforge for years. Do you have any guide on how to configure apache with Windows Active directory for authentication with group filtering? I can configure the the authentication using active directory users only and works, following some parts of this guide: http://blog.stefan-macke.com/2011/0...eros-using-debian-and-windows-server-2008-r2/ but is there a way to filter the authentication based on groups? For example, only users that are members in a particular group are allowed to authenticate in apache. Im sorry I know I should have asked the writer of the blog, but I trusted you more as you have helped me alot in the past with my questions. Thanks,
