Parameter
Description
crlPath

parameter should be commented out by preceding the line with a #.
ocspEnabled
Enables and disables the use of OCSP.
ocspDefaultResponderURL
IP address and port number for a default OCSP responder, for 
example: 
http://192.168.42.4:8888
ocspCRLFallbackEnable
Enables and disables checking CRLs if no OCSP default responder 
is specified and no OCSP URL is found in the certificate, or when a 
responder cannot be reached. 
ignoreRevocationCheckErrors
Specifies whether to ignore revocation check failures for CRLs. 
When you use OCSP, this parameter should be commented out by 
preceding the line with a #. Ignoring revocation check failures is not
