title: Can we Authenticate user of specific group in Active Directory
body: <p>I can Authenticate user in Active directory but I need to know can we authenticate a specific user in group if we have multiple groups.
  Basically I am redirecting to <a href="http://[mydirectory].onmicrosoft.com" rel="nofollow">http://[mydirectory].onmicrosoft.com</a> and validating the user but I need to know do we have mechanism to validate a user from specific group so that I can give access according to that.</p>
