I'm a bit confused by your answer. Are you saying that in the Snap server UPS configuration page I should use the servers root id and pw.
I don't think that would work as it's specifically asking for the APC username and authentication phrase. I've included a screenshot below for clarity.

The image function doesn't seem to be working so I've included a link to it. If this doesn't work on your end let me know and I'll look for another way.
