Fatal: Failed to execute CreateActiveDirectoryEndpoint. ERROR MESSAGE: Active Directory Endpoint 'Test_AD Endpoint' creation failed: Connector Server Add failed: code 80 (OTHER-NamingException): failed to add entry eTNamespaceName=ActiveDirectory,dc=im,dc=etasa: javax.naming.NamingException: The CCS Manager is not enabled and no remote server is configured for endpoint type 'ActiveDirectory' (ldaps://[JCS HOST]:20411),
The connector server was installed without C++ connector server management. Run the repair function on the connector server setup.exe and install the C++ connector server, keeping all other settings the same. Once that is done, restart the services and everything should now work as expected.
