RADIUS authentication for user portal: access denied

Question

Hi, 
 I managed to configure RADIUS authentication against a Windows Server 2012 R2 NPS. Test for both NAS identifieres (ssl and portal) were successful. However, when I try to log in to the user portal, I get 
 2017:06:28-13:16:44 sg-name aua[26148]: id="3005" severity="warn" sys="System" sub="auth" name="Authentication failed" srcip="[ip]" host="" user="tdi" caller="portal" reason="DENIED" 
 User Portal is set to "allow all users" 
 Firmware is 9.414-2 
 Can anybody help? 
 Best, 
 Tim

I suspect that that's a misleading message, Tim, and that the user "tdi" has not been synced to the UTM. Check #6 in Rulz . 
 In any case, I don't like using RADIUS for user authentication, so my recommendation would be to use a Backend Group based on a Security Group in AD and to sync the users in that Group to the UTM.
