Juniper CPPM MAC Auth

    I'm having a strange issue, if anyone has seen it before before I start opening TAC cases

    We have a mixed environment of Juniper and Cisco switches both authenticating against CPPM. If i add a device to the guest device Repository, and attempt to have it authenticate it while connected to a Juniper switch, it fails. Stating:

    "MAC_AUTH: No password in request. Not attempting MAC authentication
    EAP-MD5: Authentication failed"

    The strange thing is, it works fine if I plug into a cisco switch. It also works fine on Juniper Switches, if I add the device to the endpoint database and remove it from the guest device database.

    Anyone see anything similar? 

    Thanks,
    Chris

    Juniper switches do not send the MAC address as the password. See here: http://community.arubanetworks.com/t5/Security/Error-Code-209-No-password-in-request-MAC-authentication/m-p/152942

    Thanks Tim,

    I did see that post, but I thought since some requests were going through okay, it was just the guest devices that were failing, I just had a config error somewhere. I'll look into the diffrent auth source that was posted in that thread.

    Hi cappalli,

    i have the same issue with aruba switch 2920 whith integration with clearpass for MAC authentication.

    I am recieving below error:-

    "MAC_AUTH: No password in request. Not attempting MAC authentication
    Cannot select appropriate authentication method"

    Do you have any idea how to make clearpass check only MAC address as username without checking password OR how can we do something in aruba switch ?

    Hi,

    Did you ever find a way to insert a password in the mac auth request?

    Thanks,
