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?

Juniper switches do not send the MAC address as the password. See here:

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.
