BadUserAccessDenied: User does not have permission to perfor

Post by SeongsuByeon »

Dear all,

I am trying to add nodes to the MDE server.
This MDE server has an authentification setting with Username and password.
I can access Server and add node via UaExpert client, but I am getting an error when I tried to access the Server with OPC UA Client(python).

I set the user and password in the code as the same as the UaExeprt setting.
But I am getting "BadUserAccessDenied" error whenever I tried to add_folder.

Can you please give me an advice on this issue?
Is this credential issue? Or python OPC UA client cannot add the node to the Server.

Best regards
Seongsu Byeon

Hello,

if it works fine when using the UaExpert, it is quite clear that your clientside Python implementation is buggy. You should contact the supplier of the python and ask to fix the code. You may analyse the traffic using wireshark to figure out the what is wrong in your code. Alternative option is to switch to one of our commercial libraries, instead using the python.

In this forum we support software libraries and tools of Unified Automation only.
