Hi Alan,
The config is pretty straight forward. Here you go:
# User check from user file
<AuthBy FILE>
Identifier user-file-auth
# Location of the users file
Filename %D/users
# Suppoted EAP Types and session info
EAPType PEAP,TLS,MSCHAP-V2
EAPTLS_MaxFragmentSize 1024
EAPTLS_SessionResumptionLimit 60
# Certificate Info
EAPTLS_CAFile %D/certs/ca.pem
EAPTLS_CertificateType PEM
EAPTLS_PrivateKeyFile %D/certs/%h.pem
EAPTLS_CertificateChainFile %D/certs/%h.pem
# This flag tells EAPType MSCHAP-V2 to convert the inner EAP-MSCHAPV2
request into
# an ordinary Radius-MSCHAPV2 request and redespatch to to a Handler
# that matches ConvertedFromEAPMSCHAPV2=1
EAP_PEAP_MSCHAP_Convert 1
# Deal with MPPE keys
AutoMPPEKeys

Subject: [RADIATOR] PEAP from Radiator via Juniper switches
All,
I ran into an interesting issue. I am trying to do PEAP/MSCHAPv2 via Juniper
EX switch to Radiator. I am seeing the Access-Request come in, and Radiator
responds with Access-Challenge which is dropped by the EX. However, I have the
same switch pointing to Microsoft NPS and everything works flawlessly.
Looking over packet captures and debugs on the Radiator I noticed the following
difference in responses:
- NPS returns "Authenticator" and following AVPs:
o Session-Timeout
o EAP-Message w/ EAP Request 1, Id 1, Type 25 (PEAP), Start Flag and PEAP
version 0
o State
o Messages-Authenticator
- Radiator returns "Authenticator" and none of the AVPs.
I am suspecting that Juniper EX has an issue with this and that's why it's
dropping the frames, while Cisco IOS switch is absolutely fine and forwards the
traffic back to the client w/o much of a consideration.
Is there any easy way to force Radiator to add the same attributes to the
Challenge as NPS?
Thanks.
