By setting strictcrlpolicy=yes a strict CRL policy is enforced on
both roadwarrior carol and gateway moon. Thus when carol initiates
the connection and no current revocation information is available, the Main Mode
negotiation fails but an OCSP request is issued to the OCSP server winnetou.
When the second Main Mode trial comes around, the OCSP response will be available
and the IKE negotiation completes.
