Add support for a User.FullName SAML attribute
Review Request #12633 — Created Sept. 23, 2022 and submitted
If User.FirstName or User.LastName is not specified, we try to look for a User.FullName attribute and split that on the first space to get a first and last name. This was necessary because some IdPs only let you specify a full name.
Applied this in our container build and tested it live at reviews.imfreedom.org using JetBrains Hub as the IdP.
