Arvados

Customer request: managed property rule that requires that a property is set to a valid Arvados unix username.

To maintain database integrity, updating the username on the user record should update all instances of the user name on this managed property.

Use case: apps are storing metadata in Arvados, but are not aware of Arvados user uuids. They aware of the organization's unix usernames (because that's what the single sign on system gives them). Want to store usernames with validation on the API server (instead of free text).
