This is going to sound like a strange question but how can an outside user get added as a registered Service Desk Customer in Jira Service Desk?
I'm asking because neither me, nor apparently any of my colleagues, setup a particular customer as a user, yet somehow this person used our [still being developed] system to submit a request to us.
We don't want to ask him how he did this because it would make us look foolish but it is indeed a real mystery.
So what are the ways a person could get added as a Jira Service Desk customer?
