Configuring CRLs

L3 Networker

All,
I am using a microsoft CA to issue machine certificates for global protect authentication.  All is working, but the downloading of my internal CRL.  Is there something I need to configure besides checking the "User CRL" option in my certificate profile?  I have changed the publish time on my CA, have revoked a working cert, but still able to connect via Global Protect.  I ran the "debug sslmgr statistics" and my Certificates revoked by CRL are at 0.  Is there something else I need to configure?

Thanks,
Dan

Hello Dan.

Checking the "use CRL" option should be sufficiant.  The caviots would be, that if the firewll can not get to the CRL imbedded in the certificate, it would be considered valid.  Also, if there is no CRL in the certificate, same behavior.  You can check your "service routes"(by default the MGMT port), and make sure that the firewall can get to the CRL to check the certificate status.  The route used for CRL is the same as OCSP.  Hope this helps.
