This parameter specifies the port to connect to the LDAP host. The default value is 389, the standard port for unencrypted LDAP. If UseSSL is specified, the default value is 636, the standard port for encrypted LDAP. Port can be a numeric port number or a symbolic service name from etc/ services or its equivalent on your system. Usually, there is no need to override the defaults. Port can contain special formatting characters. A typical use of special formatting characters is with GlobalVar and command line arguments.

Here is an example of using Port:

# Connect using the SSL encrypted port
Port 636
