Hello  
I’m new to Ignition, I worked for 27 years for another package manufacturer (Profixxxx I will not name) . I’m starting with ignition and took the training on the University, but I have a question. I have a project that uses Default User Source and it works fine, I also have a ADMINISTRATOR user setup. On this project I can launch the vision client and log on. As soon as I change the User Source to OPC UA and restart, I cannot pass the authentication on the Vision client. The system is in Trial mode, so may be related…Thanks for your input…Phil

The OPC-UA user source is intended for when other systems’ OPC-UA clients connect to Ignition’s OPC-UA server. What prompted your effort to use it for the rest of Ignition?
