Dear Antonio,
The support staff gave me the required code changes.
You need to make changes to a file called ocrc.c in a method called
combinecredentials under directory oc2. The support staff will open a
ticket on github and merge the changes and you can presumably download and
rebuild and reinstall at that point.
Best regards,
Ashwin.
