The problem

I have created a bash script to authenticate against (planning to use LDAP, but right now it's an empty script). I find that when I authenticate against it, I get logged in, however HA does not seem to recognize my user name. See screenshots attached where it would expect it to show my name/uploaded picture.
Authentication against HA's password works correctly.

(first screenshot after login against command line auth, second one after local login)
