Hey Naveen - 

Although the spec is currently for keeping the usernames unique globally, domains (part of the V3 API setup) will allow us to have a boundary/barrier for uniqueness if that's desired.

The quirk that is keeping it in place is generally *not* mandating that the end user - when authenticating - know the "project/tenant" name to which they're authenticating. If we allowed tenant-uniqueness for usernames, then in order to log in and guarantee uniqueness so we could authZ someone, we would need to know the tenant up front as well. Current systems (like logging in to the horizon dashboard) *do not* require that.

Keystone today is enforcing uniqueness for a name  and prevents creation of the same user across tenants. Is there a plan to use (tenantID, name) as a composite key instead of just the name?.
