The fix was assigned to Fred Roos from fruition while he was at 25 Science Park. Backeberg and Roos sat in a cubicle and pair-programmed the solution, saved as update set 2014/01/30 - 1. The fix is a modify to the user import transform scripts to treat these unicorn alumni as active users, even though Central Auth knows they have graduated and should be inactive. This fix was a good start, but there were lingering problems. Those issues were finally settled on update set 2014/03/28 - 1.

Testing the fix

We need to identify some unicorn alumni, and then confirm their status in the system.

When I compare those I get like 3640 active 2013 alumni, and 18 inactive 2013 alumni. I don't see any reason it should not be 100% active, and I think there's a subtle bug in the way Fred wrote the alumni check. I think this needs a slight amount of work to be correctD941 works properly, there should be zero users who graduated in 2014 and are NOT set active.

How to ingress fake mail to TEST

It is possible to ingress fake mail to TEST, but the process is a lot of effort for low return. Basically, the way you do this is you send mail to PROD service now as the user you want to emulate, then you copy and paste the received message details from PROD service now into TEST service now, then tell ServiceNow to 'process message' on the fake received mail you created manually in TEST. Does that sound hard? It is. Verifying the user detail is a sufficient test of this bug.
