If you want the SCIM HTTP connection handler to use SSL, which is mandated by the SCIM specification, you need to enable a Key Manager provider and Trust Manager provider.

To enable SSL during the Directory Proxy Server's initial setup, include the --ldapsPort and the --generateSelfSignedCertificate arguments with the setup command. If your server already has a certificate that you would like to use, set the key-manager-provider to the value you set when you enabled SSL in the Directory Proxy Server, or define a new key manager provider (see Configuring HTTP Connection Handlers).
