We already had all the crl.* entries. Adding the ocsp.* entries fixed the issue 
for us. 

Thanks!

Subject: Re: Apple Safari users get certificate warning from CAS server

Macs started using ocsp by default in the latest release.  The servers 
used aren't in the default allowed hosts list for the 
unauthenticated/temp roles.

Try adding the ocsp.* host entries for your cert provider in the 
unauthenticated and temp roles.  This cleared up the problem for us (CCA 
4.8.2).
