simple_example_auth.py doesn't work properly

I tried running `demo/simple_example_auth.py` (without any changes). I accessed it through my web-browser, when I clicked `Log_me_in` it wouldn't login.
I still get the same output even after clicking login several times:
```
Hello, I'm Jack, I'm NOT logged in.

Log me in
Log me out

Check my permissions, when i'm logged in and logged out.
Can I listen?
Can I speak?
```
Which also makes `/listen` an unauthorized page.
