Freeradius authentification against Kerberos

[Wang, Yu]

You can use third party plugins but I strongly discourage you to use EAP-TTLS with Kerberos/PAP because it has security holes. We use FreeRadius and NTLM. In searching more efficient method than NTLM, I looked into EAP-TTLS with Kerberos but a brother university network engineer showed me how a hacker could steal user passwords easily with EAP-TTLS/Kerberos. I completely abandoned the idea of using it.

For your environment, PEAP MSCHAPv2 will work.

Hey thanks for your fast answer.

As a Windows 7 client, i can only authentificate PEAP - MSCHAPv2, right?
I looked at the network settings, i did not find EAP-TTLS. Is it right?


Cannot use PEAP MSCHAPv2. You have to use EAP-TTLS.

Hi,

I'm a newbie with Freeserver. It is my first time with it. I try to make a configuration against Kerberos with your freeradius-server on centOS 6.5.
I use FreeRadius 2.1.12


Please use 2.2.5 if you can.

But now I got everytime the error: "no authenticate method (Auth-Type) found for the request". So every user got a reject.
I setup the server like explained at this tutorial from eduroam.us<http://eduroam.us/>: https://www.eduroam.us/node/45

Under authenticate {}, make sure you have following lines:

        Auth-Type PAP {
                pap
        }
        Auth-Type Kerberos {
                krb5
        }


My problem is also that a PEAP - MSCHAPv2 auth from a Windows 7 - PC does not work.

Cannot use PEAP MSCHAPv2. You have to use EAP-TTLS.


Can anyone help me, please?

I attached the logs.

Thanks, and best Benjamin.
