Is there any update since this thread from 2021 on OPC UA X509 certificate authentication?
I am trying to experiment with Rockwell's FT Optix Studio and setup an OPC UA connection to one of our Ignition development servers. FT Optix does not appear to support username/password authentication, and Ignition does not appear to support X509 cert authentication.
Has this been implemented, or is it on the road map?
