Spring Security Support
Storm Path is an example of an API/Service that provides all the same functionality as Azure AD B2C, and actually integrates with Spring Security very easily.
They provide code samples too:
It would be fantastic, and ensure a much wider adoption market, if you were to create an open source project that provided the same easy integration and adoption.
This not planned for the next 6 months, but it is on the roadmap.

We are developing a Portal for Solar distributed energy where the residential users will check the Information about generated energy. We are realizing the OAuth authentication with success using the Spring Security library but without use the new policy mechanism. However we want use the B2C to our customer use your own email as login, then we need use new policy feature with spring. Could you provide a sample of Azure B2C integrated with Spring Security?
