Hi!
First of all you need an Advanced Authentication server. In CA Mobile API Gateway we have build assertions that can be used to communicate with that server.
Answers to questions:
- Integration works via APIS's. Either SOAP interfaces or REST interfaces. The gateway receives a request, forwards it to AdvancedAuth and receives a result. The gateway then either continues or fails the request, depending on the policy of the API
- Not sure if I understand this question. Please provide a few more details
- This depends on your setup. If you would use it with OAuth protected API's the client would send a request to CA Mobile API Gateway
I hope this helps!
