title: realm permit -g not limiting login groups
body: <p>I've set up a Raspberry Pi 2 b with a Fedora 23 distro, I've been able to successfully join to our active directory domain using realmd's realm join. I am attempting to limit who may log in by active directory group. After running:</p>
  
  <pre><code># realm permit -g adgroup@domain
  </code></pre>
  
  <p>Anyone with a domain account is able to log in regardless of if they are members of the group.  I've run realm list and verified the login-policy is set to allow-permitted-logins and the desired group is part of permitted-groups.</p>
  
  <p>The specific linux distro is Fedora-23-remix-rpi2-xfce-1-raw</p>
  
  <p>If anyone else has run into this problem, I would greatly appreciate the help.</p>
