Login failed: Login credentials valid but no identity could be found

[FunkMonkey]

I discovered 2 login problems:

I got this on version 1.5.6 after logging out and trying to log in again:

Having a user called user or e.g. foobar gives me a different error:

Interestingly the user andre does not work with the cass-npm library.

user and foobar initially throw an error in the library (undefined: error: EcPpkFromPem: Error: Invalid PEM formatted message.). Afterwards when trying to log in I get the malformed URl error above, BUT then the cass library works without errors.

Steps to reproduce

1. Create a new user newuser
2. Log out, log in - works fine
3. Connect with newuser credentials using cass-npm
4. First time: undefined: error: EcPpkFromPem: Error: Invalid PEM formatted message.
5. Second or third time: login via cass-npm suddenly works!
6. Try to log in using CaSS web UI - Login failed: URIError: malformed URI sequence (login basically broken now for newuser)
