Show Azure ADFS Display Name in Confluence / Jira

[Steven McDowall]

We have a new employee who's official first name is one thing, but he has gone by his middle name for the last 30+ years.

We added his desired name in our Azure ADFS in the Display Name field and many other systems we use w/ ADFS SSO show the Display Name as his name.

However, Atalassian Confluence / Jira does not -- and of course since it uses AD Sync we can't change it there. 

Yes, he can change his PUBLIC name -- but that is not the desired result. He wants his desired first name to be shown and selectable etc.
