This componentauthenticates the user on an OPC UA server, and ensures the password requirements are adhered to. Any new OPC UA user should be associated with this scheme.
This component must be added to the station’s Authentication Service. Then, when creating a new OPC UA-specific user, you configure the user’s authentication scheme as: OpcUaAuthenticationScheme.

any changes on OPC UA server side, you must disable and then re-enable
the OPC UA server.
