Ok, it looks as though my predecessors have created multiple Organizations with a variety of names and associated systems and licenses in past years with SCC.

As a result it looks like my SUMA Evaluation license is on one, and the credentials I used to register SUMA post-installation are on another.

Hopefully it doesn't take too long to run through the cleanup/consolidation of these accounts into a single one. This seems a worthwhile time to do so as there's an appetite for SUMA, but less so for cleanup (surprise). I daresay it will make life in future with SUSE an order of magnitude easier.
