Hi,
Can Service Identity option in ACS be applied for Provider-Hosted App hosted as a Cloud Service? I understand that Service Identity is used for direct authentication of ACS without using Identity Providers and mainly for REST webservices or any client- service model, but I found that we need to write a code implementation in the visual studio project to make use of Service Identities and implementation is required at both client and service.
In Provider-Hosted App we cannot do code implementation for Client Package (App package) which is uploaded to App Catalog as it is just a manifest file. So I just want to know whether can we use Service Identity option of ACS for Provider-Hosted App and if answer is "yes" then how does the authentication works from SharePoint when requesting access tokens with ACS.
Appreciate your valuable suggestions.
Thanks,
Mithun
