Just a heads up that the LinkedIn OAuth is no longer working because we need to update it for OAuth 2.
We also want to move away from the facebook clone type consumer social networks and customize Anahita for knowledge sharing and open science applications. Therefore, we want to add support for additional providers such as Google, GitHub, and GitLab. The development will take some time, but it will be perfect for Anahita.
Ideally, we would want to have the Anahita Connect app to be both a consumer and provider of OAuth service. We can not only authenticate Anahita users against external services such as Google or Github but also turn Anahita itself into an OAuth provider.
We may decide to remove support for Facebook for several reasons. For example, Facebook is very much a consumer service and not being used professionally in the science and education world. They also have a poor track record in terms of privacy and data collection.
