By default Safeguard Authentication Services for Smart Cards retrieves any CRLs that are required to verify the certificates presented by Active Directory and automatically updates these as they expire and new certificates are issued. To be able to retrieve CRLs, the certificates to which they correspond must contain a CRL distribution points extension that contains an LDAP URI from which to download the CRL.
CRLs are stored in the /var/opt/quest/vas/crls directory.
