Fix authentication configuration

[lazyfrosch]

auth_method => external
Was not handled at all, but provided as defined type.

admin_users => [ list ]
Was written into the wrong ini value

I'll add a few lint fixes soon.

These are easy to fix...

Will you fix those or would you like a pull request?

[lazyfrosch]

Yep, working on it.

BTW, I've enabled the Travis builds for that repo...

👍

[lazyfrosch]

@arioch would it be okay for you to change the fixtures to HTTPs links?

[arioch]

That would save me the trouble of doing so. 👍

[lazyfrosch]

Should be ready for merge :)

[arioch]

Merged upstream!
Thanks Markus.
