A new configuration variable
<HttpsMutualTls>true</HttpsMutualTls>
enables the mutual TLS authentication support. The behavior of the TLS endpoint changes as the following:
HttpsMutualTls is true:
The server checks the trust on the certificate which is used by the client for TLS authentication. It must be a valid OPC UA application certificate which is trusted.
A client can still connect without providing a client certificate, but then it is only able to call discovery services.
In order to create a session, the client must use the same application certificate that was used for the TLS channel.
HttpsMutualTls is false:
- There is no application authentication. The server endpoint uses security None and there is no client application authentication.
Instead, only user authentication is used to secure the server, anonymous user authentication is disabled.
Discovery service calls are supported.
