Minor Description
Currently a user in Nifi has only one attribute: identity. This is used both for displaying the user in the UI as well as for identifying the user internally. When the authentication is provided by an external system (eg LDAP, Kerberos or OIDC) the user identifier can be a numeric id or a GUID which is not very descriptive.
It would be usefull and more user friendly if the user could have a display name which can be used in the UI in the application header and also in the management screens for users.
