Could anybody compare OpenAM with Apache Fediz (or some other product) in production environment? The customer is a large bank, so there might be less features available in the product but it should be mature and stable.
If you are looking something for security core specific projects, i would advise you to choose any paid framework than an opensource framework. such as Oracle opensso :
There are plenty of other options available in market. Though, we ourselves are using openAM for authentication & authorization as the project does not need that robust framework as any banking project would require.
