Hi,
I’ve a question regarding secure channel and user session(s) in a secure channel.
We are connecting to an OpcUa server, which allows exactly one secure channel per application certificate. So if I would like to have two user session from a single OpcUa client, the supplier of the OpcUa server suggests that I should create additional user sessions in the secure channel.
As I do not know any OpcUa SDK which allows this (every SDK I know is opening the secure channel and then creating the user session withing this secure channel, but none of them have an API to add a user session to an existing secure channel), I wonder if such a limitation (to allow only one secure channel per application certificate) is within the OpcUa specification?
Thanks!

There are use cases where creating multiple sockets is problematic and some client SDKs do allow a Session to be attached to an existing SecureChannel. However, there are no requirements that any given SDK support this feature.
You need to have a conversation with the SDK vendors about this feature.
