It would be great if Zeppelin would normalizes case of usernames after authentication (let's say, to lower case).
We noticed user sometimes authenticate using different case (for example, email@example.com , next time john.dow@Epsilon.com / John.dow@Epsilon.com etc).
Apparently authentication backends don't case about case (for example, we use LDAP).
It breaks at least one thing - `notebook-authorization.json`'s `owners` field with different cases and users don't see their own notebooks - even though they are in fact are still owners. They can only see a subset of notebooks, that they created when logged in with exact same username.
Would be nice if Zeppelin normalize case, after user successfully authenticates in.
