Alan, I have now used your example to create a new version of "req.txt" and it is indeed now working:     User-Name = "tu"     Cleartext-Password = "testp2"     NAS-IP-Address = 192.168.1.106     EAP-Code = Response     EAP-Id = 210     EAP-Type-Identity = "tu"     Message-Authenticator = 0     NAS-Port = 0 Thank you so much for your help. Kindest regards, Oliver
