An incomplete version of this post has previously been posted in openssl-users@xxxxxxxxxxx and modssl-users@xxxxxxxxxx, but this post contains a lot more info. I didn't realize that the appropriate list is users@xxxxxxxxxxxxxxxx I'm trying to get Apache to do Client certificate verification with OCSP-validation. It works without OCSP, but OCSP-validation fails when I turn it on. The error is "OCSP_check_validity:status too old", but that doesn't make sense because the clocks are within 2 seconds. I'm not using the OCSP-responder address in the certificates "Authority Info Access" (http://sithsocsp.trust.telia.com), because it is not reachable from my system. However, the same responder is reachable using another address (http://ocsp.trust.telia.com). I have verified that if I use openssl directly from command line it will verify OK. >openssl ocsp -issuer /usr/local/apache2/conf/SITHS_CA_v3.cer -CAfile /usr/local/apache2/conf/SITHS_CA_v3.cer -cert /mnt/download/uwcert.cer -text -url http://ocsp.trust.telia.com . .

This is the expected behavior because my computer does not have access to sithsocsp.trust.telia.com. CASE 3/ If I set: SSLOCSPDefaultResponder http://ocsp.trust.telia.com - Try to authenticate - It will fail as in 2 above. - Do NOT close the browser (IE, by the way) - set: SSLOCSPDefaultResponder
