Description of problem:
When you fail a login, it locks the username and only lets you
adjust the password field. If you made a typo in the username,
you have to exit out of it, and restart the entire application.
Would it be possible to allow free editing of both the username
and password field? I'm not sure what the benefit to doing it
the way it was implemented is.


Version-Release number of selected component (if applicable):
redhat-access-gui-1.0.0-3.el7

How reproducible:
100%

Steps to Reproduce:
1. Launch redhat-access-gui
2. Enter incorrect credentials and try to login
3. Try to shift tab back to username or click on the field and correct a mistyped username

Actual results:
That field is locked

Expected results:
Can edit the username field in case I made a typo there, and that's why my login failed
