3468.0. "Timed CHAP Authentication?" by SNOFS1::KHOOJEANNIE (Hangovers: The Wrath of Grapes?) Tue Mar 18 1997 00:20

    A customer of ours is planning to use a DECserver with a leased line to
    each PC.  The security mechanism he would like to implement is CHAP only or
    CHAP in conjunction with the RADIUS server.
    
    However he wants to have the authentication happen on a timed basis,
    say, every 10 minutes or so.  Can we do this with CHAP only or
    CHAP/RADIUS?  If not, how do we guarantee on-going authenticity?
    
    Thanks for your help
    Jeannie

If not, how do we guarantee on-going authenticity? I presume it's the DECserver that is interested in continual authentication of the PC, and not the other way around. This would require the DECserver (DNAS) to implement periodic CHAP re-authentication. We do not currently have this feature. Most PC clients will respond properly to mid-session challenges.
