Title: RE: CRL question

It's for the authentication of users. The situation is the following:

The users can login to our website via a Federal service of the belgian government. Thus, all the login is not part of our application. The federal service sends (posts) a SAML message to our application with the info of the user and the status of the login (success, failed, etc.). We need to check the validity of the saml message before allowing the user to enter to our website. We manage quite sensitive information, so we cannot ignore the CRLs. Since this website is intended for the clients, 20-30 seconds waiting for the login is in the limit of the acceptable. That's why we want to (if possible) cache the CRLs, for diminishing that waiting time.

Thanks,
regards,
Miro

My experience is that most folks just pretend that CRLs don't exist 
and go merrily on their way.

Are you authenticating users or system entities with your 
certificates?  If it's the latter, I think it's easier just to dump 
the PKI and use bi-lateral trust.
