RADIUS Authentication not working - log says "bad response authenticator"

Question

Hi, 
 
 When testing with the SG integrated testing tool, log says 
 2017:06:22-17:18:04 tuk-gw aua[26875]: id="3006" severity="info" sys="System" sub="auth" name="Spawned child for authentication test" 
 2017:06:22-17:18:04 tuk-gw aua[26875]: id="3006" severity="info" sys="System" sub="auth" name="Authentication test request: m:radius, f:ssl, u:tdi, ip:0.0.0.0, host:" 
 2017:06:22-17:18:04 tuk-gw aua[26875]: id="3006" severity="info" sys="System" sub="auth" name="failed to recv packet from radius server: bad response authenticator (EBADAUTH)" 
 2017:06:22-17:18:04 tuk-gw aua[26875]: id="3006" severity="info" sys="System" sub="auth" name="Authentication test failed: failed to recv packet from radius server: bad response authenticator (EBADAUTH)" 
 
 I configured the Windows 2012 R2 NPS according to the Sophos Howto . Nothing special there. What am I missing? 
 
 Thanks in advance.

Hi, Tim - first time I've seen you post here - welcome to the UTM Community! 
 You're not describing exactly the same phenomenon, but I wonder if Yannick Wellens' solution isn't what you need.
