Trust relationship for certificates

The Configurator facilitates management of the client certificates on the server. In the project settings you can classify the certificates as trustworthy or refuse them on the UA Endpoints tab in the Client certificates area.

After an OPC UA Client has attempted to connect to a secure server endpoint for the first time, the client certificate is deposited on the server and declared "rejected". The server administrator can subsequently enable the certificate. A subsequent connection attempt of the client with a secured endpoint will then be successful.
