CRL Distribution 

Points and OCSP 

checking 

Select this check box to have the ZyWALL check incoming certificates that are 

signed by this certificate against a Certificate Revocation List (CRL) or an OCSP 

server. You also need to configure the OSCP or LDAP server details.

OCSP Server

Select this check box if the directory server uses OCSP (Online Certificate 

Status Protocol).

URL

Type the protocol, IP address and pathname 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.

ID

The ZyWALL may need to authenticate itself in order to assess the CRL 

directory 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 

CRL directory server (usually a certification authority).

Certificate 

Information

These read-only fields display detailed information about the certificate. 

Type

This field displays general information about the certificate. CA-signed means 

that a Certification Authority signed the certificate. Self-signed means that the 

certificate’s owner signed the certificate (not a certification authority).  X.509 

means that this certificate was created and signed according to the ITU-T X.509 

recommendation that defines the formats for public-key certificates.

Version

This field displays the X.509 version number. 

Serial Number

This field displays the certificate’s identification number given by the certification 

authority.

Subject

This field displays information that identifies the owner of the certificate, such as 

Common Name (CN), Organizational Unit (OU), Organization (O) and Country 

(C).

Issuer

This field displays identifying information about the certificate’s issuing 

certification authority, such as Common Name, Organizational Unit, 

Organization and Country. 
With self-signed certificates, this is the same information as in the Subject 

Name field.

Signature Algorithm

This field displays the type of algorithm that was used to sign the certificate. 

Some certification authorities use rsa-pkcs1-sha1 (RSA public-private key 

encryption algorithm and the SHA1 hash algorithm). Other certification 

authorities may use rsa-pkcs1-md5 (RSA public-private key encryption 

algorithm and the MD5 hash algorithm).
