During recent development, we encountered a requirement to implement OPC UA encryption, user management, and data auditing simultaneously.
The current situation is as follows:
After disabling unencrypted communication channels (No Security) in OPC UA, the user login and user management functions stop working. Users cannot log in even when the correct username and password are entered.
Could you please advise whether this issue can be resolved, or whether any additional configuration is required?
There are some additional settings required in Automation Studio and mapp 6.x compared to mapp 5.x, but since you’re using mapp 5.16 I can’t think of any “gotchas”.
How are you “logging in”? Is this through a mappView HMI or are you using the MpUserXLogin block to log in through the application?
Are your credentials stored locally in Automation Studio’s User-Role system or are they in an Active Directory server?
Are you getting any errors in the Logger when you try to authenticate?
