Hello, I have implemented an embedded client that sends authentication requests either with User-Password (Attr Type 2) or CHAP-Password (Attr Type 3). This works perfectly, the requests are accepted or rejected from FreeRadius. 1. But how is User-Password (Attr Type 2) declared? Is this PAP? It don't seems so, since in all descriptions PAP means plain text, and the User-Password is MD5'ed with random authenticator and shared secret. How to label this authentication for the client user? 2. When I use CHAP-Password (Attr Type 3) in the request it works without problems. But shouldn't this attribute part of a Challenge Response? How can I activate that? Since I wrote my own client, I want a clean implementation and make no mistakes.
