Asp.Net MVC: SSO + AD group?

[koraycas]

I need to make a web application(asp.net mvc 4) that uses the windows auth(SSO) to authorize users.But I need to authorize only users which are in special groups(no special sub roles after, it's only to define if we have access or not).What should I do to achieve this?I saw there is an "ActiveDirectoryMembershipProvider", but I don't know if it fits my needs(SSO, and check for the group).So what should I do? A custom membership provider? A custom attribute? Will the \[code\][Authorize("MyGroup")]\[/code\] works?I never made any auth against an ActiveDirectory registry, thank you for your help
