Certification Path Click the Refresh button to have this read-only text box display the end entity’s
certificate and a list of certification authority certificates that shows the hierarchy of
certification authorities that validate the end entity’s certificate. If the issuing
certification authority is one that you have imported as a trusted certificate, it may be
the only certification authority in the list (along with the end entity’s own certificate).
The ZyWALL does not trust the end entity’s certificate and displays “Not trusted” in this
field if any certificate on the path has expired or been revoked.

and OCSP checking
Select this check box to turn on/off certificate revocation. When it is turned on, the
ZyWALL validates a certificate by getting Certificate Revocation List (CRL) through
HTTP or LDAP (can be configured after selecting the LDAP Server check box) and
online responder (can be configured after selecting the OCSP Server check box).
OCSP Server Select this check box if the directory server uses OCSP (Online Certificate Status
Protocol).
URL Type the protocol, IP address and path name of the OCSP server.
ID The ZyWALL may need to authenticate itself in order to assess the OCSP server. Type
the login name (up to 31 ASCII characters) from the entity maintaining the server
(usually a certification authority).
Password Type the password (up to 31 ASCII characters) from the entity maintaining the OCSP
server (usually a certification authority).
LDAP Server Select this check box if the directory server uses LDAP (Lightweight Directory Access
Protocol). LDAP is a protocol over TCP that specifies how clients access directories of
certificates and lists of revoked certificates.
Address Type the IP address (in dotted decimal notation) of the directory server.
Port Use this field to specify the LDAP server port number. You must use the same server
port number that the directory server uses. 389 is the default server port number for
LDAP.
