This project, apparently, has support for OAuth. It, also apparently, is currently broken.
Once we have documentation about how this works (see FINERACT-xxx), and somehow looked more into why it's currently broken and how to fix it, we should ensure future non-regression by adding test coverage for it.
As far as I understand, it won't be possible to simply create another "normal" integration test for this - because OAuth support is activated by a build time property (in how it's currently implemented). Therefore, this is probably more something someone would want to add to https://github.com/apache/fineract/blob/develop/.travis.yml?
