Cisco and Microsoft PKI
« on: June 28, 2018, 07:00:05 AM »
I'm trying to implement a S2S VPN IKEv2 between Cisco ASA 5510 and ISR 886VA.
This VPN will use the certificates which are issued by Microsoft CA 2012 R2.
I found a very You are not allowed to view links. Register or Login how to configure NDES enrollment with Microsoft CA 2008 R2, but it seems doesn't work with 2012 R2. I have stopped on the step "checking the certificate" (5:30). I don't receive requested certificate. Moreover I don't see any requests on Microsoft CA. Although I got the root certificate.
Could you please help me?
Thank you in advance!

If you check the CA, do you see any pending certificate. Can you even request  certificate manually vis the /certsrv page? Two most common issues with SCEP is usually not having automatic approval enabled and not having security challenge disabled on the CA, which of which I believe controlled via registry
