Add Additional Servers to the Setup for Load Balancing and Failover

The following procedure describes the process for adding additional servers to the setup for load balancing and failover.

Note: When you create or modify a Policy Server object in the Policy Server User Interface, use ASCII characters. Object creation or modification with non-ASCII characters is not supported.

To add additional servers to the setup for load balancing and failover

1. In the Directory Setup group box of the User Directory Dialog, click Configure.

   The LDAP Setup Dialog opens.

2. In the Add an IP Address or Name group box, select either IP Address or Domain Name.
3. If you selected the IP Address radio button, in the LDAP Server IP Address fields, enter the IP address for the LDAP user directory server.

   If you do not know the IP address of the LDAP server, click the DNS Lookup button. Enter a host name in the DNS Lookup dialog and click OK. The DNS Lookup dialog closes and the IP address for the server appears in the LDAP Server IP Address fields in the SiteMinder LDAP Server dialog.

4. If you selected Domain Name, enter the domain name of the LDAP server in the Domain Name field.
5. In the Port field, enter a port number for the LDAP server.

   If you do not specify a port number, the Policy Server uses the default port (636 for SSL and 389 for non-SSL).

   Note: If you assign a port number to the last server in a failover group, that port number is used for every server in the failover group.

6. Click either Add Load Balancing or Add Failover to add the IP address or domain name to the list in the Current Setup group box.
7. If you are adding another server for failover, select the IP address or server to which you want to add a failover LDAP server in the Current Setup group box.
8. Repeat steps 2 through 4 to enter another IP address or domain name.
9. Click Add Load Balancing or Add Failover.

   Note: If you are adding a server for failover, the failover directory must use the same type of communication (SSL or non-SSL) as the primary directory, since both directories share the same port number.

   The Policy Server User Interface displays the IP address or domain name in the Current Setup group box list below the existing server(s) for load balancing or beside the existing server(s) for failover.

   Note: To remove an LDAP server (and any associated failover servers), select its IP address and click Remove.

Note: You can add the same server multiple times for load balancing to force more requests to be serviced by a specific system. For example, consider two servers in a group (Server1 and Server2). Server1 is a high-performance server and Server2 is a lesser system. You can add Server1 to the load balancing list twice so that it will process two requests for each request processed by Server2.
