Summary0003837: 7.7.5 ApplyChanges() - clarifications needed regarding private keys and existing/new connections
Description

CMPWG Sep-15-2016:

We think there needs to be some additional commentary that describes the situation for connected clients. For example:

  • what should happen to currently connected endpoints if the private keys do not change? can they stay connected? what about on re-connect, is the client assumed to auto-trust the new public cert?

  • what should happen if the private key is changed, and the applyChangesRequired=FALSE? does this parameter mean that the certificate is immediately put to use, and if so, what happens to the currently connected endpoints?

TagsNo tags attached.

Added following text to 6.7:
A Client should be prepared for a new Server application instance Certificate when trying to re-establish the connection by creating a new SecureChannel. This can happen due to an automated update of CA signed Certificates. In this case the Client shall fetch the new Server Certificate with GetEndpoints.

Added in OPC UA Part 4 - Services RC 1.04.16 Specification.docx
