The features are very flexible, it can be used for all kinds of projects (internal / external).
It's easy enough that even users without technical expertise in IT systems could use this software effectively! We have been using OA since 2015 - we were looking at other alternatives but found no solutions as good nor simple than ours yet complex ones would cost much more money so our choice was clear from day one :O) Our experience has shown us how great they support their customers! They provide excellent training which helps you understand everything quickly when starting up your own project within an organization where not everyone knows what samba means ;) But also keep them informed about current trends because sometimes new technologies come out fastly making some older products obsolete before there time runs down ;-) For example I think recently Microsoft announced something called ADFS4? I like that it has an easy interface, so you can easily add new users without having much knowledge of how things work in this type software (no code). It's not free for small companies; however there are other options out there if your budget allows them. We use OA as our authentication platform but we also have another product called "Moodle" which uses Moodle API integration within their own website/application - very cool!
