ESCWA can communicate to a remotely hosted MF Directory Server and its enterprise server instances. The instances use a Communication Processes to connect to the MF Directory Server. If you have configured your MF Directory Server to use TLS then you need to configure the Communications Process to communicate as a TLS enabled client.
Communications between Communications Process and a Directory Server can be secured by configuring TLS settings on the MF Directory Server Security page. See MF Directory Server Security for more information. Click Use encrypted connections, and then click Use custom server ID certificate. Specify the your certificate and keyfile information.
The Directory Server currently does not support authentication to a Communications Process using a client certificate. The Directory Server is not able to connect to a Communications Process TLS-enabled listener that is configured to require client certificate authentication.
