Hi,  
We are trying to set “custom permissions” on Tags exposed in OPC UA .  
When the Tag permission is Read/Write we can write the tag with an OPC UA client  
When the permission is “Custom” whith a role access read\_write, Writing is not allowed from the OPC UA client connected with correct role authentication.

We try several test on ignition version 8.04 version 8.05  
OPC UA Client is UA EXPERT

Is there something that we miss?
