Do not expose ugly user identifiers when assigning roles

[pdurbin]

This is a follow on to #1080 about how we currently see @ signs when assigning roles and permissions.

For Shibboleth users especially, the user identifier is long and ugly (screenshot below) and should not be shown. For example: @https://idp.testshib.org/idp/shibboleth|myself@testshib.org

@scolapasta we talked about this yesterday right? you had a solution for it, yes?

[scolapasta]

I was waiting until we have the final discussion on user identifiers / names to do this. We had previously said we would show the real name here and you would search for "Gustavo Durand" instead of @gdurand. (that is the solution I spoke of)

I want to make sure what we decide that before using it, or if we go with usernames.

Bu if I have time, I'll try to get this before our review with Merce on Monday, so it looks nice for the discussion.

This sounds like a fine solution. I opened this ticket because I don't want us to expose the internal user identifiers which can be quite ugly. Showing the name instead (i.e. "Gustavo Durand") sounds great!

This is done, but needs discussion. Right now I show name and e-mail (as an example). I could show Affiliation, though that requires a (hopefully minor) back end change.

We probably shouldn't show email addresses. When the whole world can sign up for an account, anyone could sign up and discover people's email addresses. #749 is about how we a sign up should let people know that display names will be searchable, not email addresses.

In #759 we stopped indexing email addresses for privacy.

Yes, that's why I said as an example. We never got to this in the meeting Monday, but it was meant to be a point of discussion.

Changed it to name and affiliation for now. So I can pass this to QA (we still can decide what is best, but this way no one is upset with e-mail there).
