Port Number Considerations

You can assign ports to individual LDAP servers and failover groups, or let the Policy Server use the default port numbers for LDAP servers.

The following guidelines apply when specifying port numbers:

If	Then
any server in a failover group other than the last server contains a port number	The Policy Server assumes that servers in the group that do not have a specific port are using a default port. The default for SSL is 636. The default for non-SSL is 389. For example, a failover group of servers includes the following: 123.123.12.12:350 123.123.34.34 The first server in the failover group includes port 350. Communication with that server takes place on port 350. If the first server fails, the Policy Server communicates with the second server using the default port 389 because no port was specified for the second server in the failover group.

The Policy Server assumes that servers in the group that do not have a specific port are using a default port. The default for SSL is 636. The default for non-SSL is 389.

For example, a failover group of servers includes the following:

123.123.12.12:350 123.123.34.34

The first server in the failover group includes port 350. Communication with that server takes place on port 350.

If the first server fails, the Policy Server communicates with the second server using the default port 389 because no port was specified for the second server in the failover group.
