+By setting <b>strictcrlpolicy=yes</b> a <b>strict CRL policy</b> is enforced on
+both roadwarrior <b>carol</b> and gateway <b>moon</b>. Thus when <b>carol</b> initiates
+the connection and only an expired CRL cache file in <b>/etc/ipsec.d/crls</b> is
+availabl, an ldap fetch to get the CRL from the LDAP server <b>winnetou</b> is
+successfully started and the IKE authentication completes. The new CRL is again
+cached locally as a file in <b>/etc/ipsec.d/crls</b> due to the <b>cachecrls=yes</b> option.
