Hi all, I added the option to create an authenticated connection using the OPC-UA adapter and tested it with the milo demo server. The changes are part of PR-35 (https://github.com/apache/incubator-streampipes-extensions/pull/35) in StreamPipes Extensions.
@Adrian, please let me know if it worked for you too or if you still face issues once the changes are included in the build of the 0.68-SNAPSHOT version.
