title: Authenticate with Flask-LDAP3-Login based on group membership
body: <p>I'm new to Flask and I'm trying out Flask-LDAP3-Login.</p>
  <p>I've followed the documentation here and i have it working which is great: <a href="https://flask-ldap3-login.readthedocs.io/en/latest/index.html" rel="nofollow noreferrer">https://flask-ldap3-login.readthedocs.io/en/latest/index.html</a></p>
  <p>How would i go about authenticating a user based on whether they are a member of a specific group? I see the docs mention group filtering but i'm not sure how to put it all together.</p>
