Access group SMS does not work using http-sending of SMS?

Hi, in our test-soon-to-be-production-NAV (3.4.4), we send SMS by using the HttpGetDispatcher. From smsd.conf: dispatcher1: HttpGetDispatcher dispatcher2: GammuDispatcher My username is the only user allowed to get SMS from this test-NAV. (Alert profiles, group SMS) Still, other users keep getting SMS. As far as I know, the objective of the SMS group is to limit the number of users receiving SMS (cost-perspective). Has anyone else similar experiences? It this a known bug? Suggetions? Gro-Anita NTNU IT
