Radius authentication

    Hi,

    We would like to use MS IAS as a RADIUS server for a centralized
    router management.

    We were able to make it work perfectly in PAP mode but as this exposes
    passwords we would like to use MS CHAP.

    When we just switch to MS CHAP (on the router and IAS) the
    authentication fails with AUTH_FAILURE. As there is no messages in
    Active Directory logs we conclude that the real authentication has
    never happened and the request has been rejected by IAS itself.

    Has anyone been able to make it work with MS CHAP?
    Do we need to activate reverse password encryption in Windows to make
    it work?

    Any advice will be appreciated

    Hi,

    Check your IAS and NAS configuration.
    Reverisble password encryption is only necessary if you want to use "chap".
    Use MS CHAP version 2 if possible.
