Today in on-prem ADAM, you can create Saved Views and share them with users by their user name or by their email address. When sharing a collection, you can only share using the user name.
In the SaaS world, we would like all instances of sharing assets to allow for user lookup by both name and email address. This functionality is important to us because it a. creates a consistent user experience, and b. allows a friendlier way to find someone-- because of how our active directory connection works with ADAM, our user names are our company IDs.
