Please include this information:

• What Grafana version are you using?
  v3.1.1 (commit: a4d2708)
• What datasource are you using?
  Elasticsearch/InfluxDB
• What OS are you running grafana on?
  Linux
• What did you do?
  I invited a User by an E-Mail-Address. Only LDAP signups are allowed and general user signup is disallowed.
• What was the expected result?
  It would deny my Invite if I gave an E-Mail-Address. It would allow my Invite if I gave an LDAP-User.
• What happened instead?
  It created a new user with an E-Mail-Address as user name. That user can even login and was then part of that organization he was invited to.

there is no way to disable invites right now. The option allow_sign_up only controls if users can self register, it does not control if an organization admin can invite new users or not.
