PPP Authentication with AAA PPP Default records fails

Discussion in 'Cisco' started by Georg Dingler, Sep 14, 2006.

  1. Hello,

    I got a Problem with the PPP Authentication. The BRI0 and the
    corresponding Dialer Statement (Fixed IP, no remote name) contain each

    ppp authentication chap ms-chap callin

    If the global scope contains the AAA statement

    aaa authentication ppp default none

    everything is allright and a Windows XP Client can dial in (no
    Username/Password). But with the statement

    aaa authentication ppp default local

    the login for a local user account is refused (Password incorrect).

    Any idea ?

    Hope this helps.

  4. Hello Brad,

    the problem is solved ! I changed nothing (except to ms-chap-v2 Method)
    and created a new local account *without* using MD5 for password
    encryption - and it worked without a problem !
