Points and OCSP

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

 

checking

 

 

 

 

 

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

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

 

Information

 

 

 

 

 

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).
