request may be accepted before the CRL is received.

 

 

Ignore CRL Expiration

When unchecked, ACS examines the expiration date of the CRL in the Next

 

Update field in the CRL file. If the CRL has expired, all authentications that use

 

the certificate that is signed by the selected CA are rejected.
