Repro steps:
1) Enroll a device into enterprise management (Ctrl-Alt-E during OOBE)
2) Go through GAIA flow to add a new managed user to the device
3) Log out
4) Remove the user
5) Go through GAIA flow to add the same user to the device

Expected:
* After going through the GAIA flow, I am logged in as the new user.

Observed instead:
* I see a black screen for a few seconds and then the login screen again.
* A red exclamation mark and the user's user name are shown underneath the newly added pod.
* Clicking on the pod takes me to GAIA, with the user name pre-filled. If I authenticate once more, I can log in as the new user.

Note that both the device (1) and the user (2) are managed. In all my tests, both were part of the same domain. If the device is unmanaged or the user is a consumer user (@gmail.com), the problem does not occur.

The problem only happens with the Views login flow.

Observed on kevin M70 ToT today.
