Hey @dabocs thank you for this PR. Unfortunately as you can understand it seems that @Peter-Slump does not maintain this project any longer.

My recommendation, would be to fork this project using a new name, i.e django-keycloak2, apply your PR and release a new pypi version under the new name (if you are willing of course to commit to ths burden).

Then we can add comments to the corresponding issues pointing to the forked project so users can use it isntead of this.

Thank you
