use of chap-password and mschap-resposse attributes

339 views Asked by At

With Radius I want to understand if 'chap-password' attribute can be used for authentication for both chap and mschap. Or 'chap-password' is used for chap protocol only and 'mschap-challenge', 'mschap-response' VSA's are used for Mschap based authentication.

Found a link which is explaining that Mschap uses Mschap VSAs and CHAP uses CHAP-PASSWORD AVP for authentication.

Also RFC 2548 which explains Microsoft vendor-specific RADIUS attributes doesn't say that CHAP-PASSWORD can also be used for MSCHAP authentication.
