Hi,
I am using EAP-TTLS with eap.conf, it is working, but I was looking in
debugging messages and output of sniffing that I can see the User-Name
(pepino, in this example), earlier in radius 1.17 only showed
anonymous... I see no passwords (I think that it's safe onto tunnel,
isn't it?). Is that right? That's is the debug output:
