Re: Access Challenge in freeRadius server

I am trying to authorize the ssh and telnet login users of my Redhat Linux machine using freeRadius server.

I am able to test Access-Accept and Access-Reject with right and wrong credentials respectively by configuring the file '/etc/pam.d/sshd' with entry pam_radius_auth.so.

But I do not know how to achieve and test the Access-Challenge concept.

Do you need to? ssh and telnet supplicants tend not to use protocols with challenge-response exchange.

I mean what type of input will result in Access Challenge (I know it happens when we provide partial login information but not sure how to achieve with login in real time)?
