Login requires username. Denies e-mail address


On the c9 login screen (https://c9.io/login), I am given the option to log into c9 with my username or email address.

Each time I try with my email address, it doesn’t work. However, I can log in using my username.

Does this happen to others? Might be a bug needing to get fixed. I don’t think this has been raised before.
