The server port for the LDAP connection (default is 636).
This property contains the server port for the LDAP connection (default is 636). A valid port number (a value between 1 and 65535) is required for the connection to take place. The property must be set before a connection is attempted and cannot be changed once a connection is established. Any attempt to change this property while connected will fail with an error.
For explicit SSL, use port 389 instead (please refer to the SSLStartMode property for more information).
