GlobalProtect OCSP validation not working

L1 Bithead

Hi,

 

OCSP verification configured in a Certificate Profile on my Palo Alto 3020 doesn't seems to work.

 

My GlobalProtect configuration with pre-logon is working with machine certificate but when I want to see the status of the OCSP cache on the Palo, I've an unavailable status :

 

debug sslmgr view ocsp all

Current time is: Thu Feb 2 10:21:28 2017

Count Serial Number (HEX) Status Next Update Revocation Time Reason
Issuer Name Hash
OCSP Responder URL
------- ---------------------------------------- ----------- ------------------------ ------------------------ ----------
[ 1] 44000001565A923152F9A9E91A000000000156 unavailable Feb 02 08:20:44 2017 GMT

 

Here is the error in the sslmgr.log :

 

2017-02-02 11:42:30.124 +0100 Warning: pan_ocsp_query_responder(pan_crl.c:2039): sat_verify_certs(/opt/pancfg/certificates/ocsp-verify-ca-4/all_verify_certs_sat) doesnot exist.

Yes, I've activated the NONCE support on my Microsoft OCSP Responder as mentionned here :

I've done a capture on the firewall and I see the packets OCSP Request and OCSP Response but Palo Alto

Idea anyone ?
