Click CERTIFICATES, Directory Servers to open the Directory Servers screen. This screen displays a 
summary list of directory servers (that contain lists of valid and revoked certificates) that have been saved 
into the ZyWALL. If you decide to have the ZyWALL check incoming certificates against the issuing 
certification authority’s list of revoked certificates, the ZyWALL first checks the server(s) listed in the CRL 
Distribution Points field of the incoming certificate. If the certificate does not list a server or the listed 
server is not available, the ZyWALL checks the servers listed here. 

The following table describes the labels in this screen. 

PKI Storage 
Space in Use 

This bar displays the percentage of the ZyWALL’s PKI storage space that is currently 
in use. When you are using 80% or less of the storage space, the bar is green. When 
the amount of space used is over 80%, the bar is red. When the bar is red, you 
should consider deleting expired or unnecessary certificates before adding more 
certificates.
