Docs: Sovereign Cloud Support

[iambmelt]

Hi ADAL Team,

We are working on supporting Sovereign Clouds for Teams Android app and have the following question. We are going thru the documentation here - https://identitydocs.azurewebsites.net/static/aad/sovereign_clouds.html which says
"From the Authentication result, you can read and store the cloud_instance_host_name attribute for the correct Azure AD endpoint. You must pass this value as the authority to re-initialize the Authentication context for the subsequent acquireTokenSilent calls to succeed."

How to read cloud_instance_host_name from AuthenticationResult in Android ADAL library, I couldn't find any method or property with that name.

Thanks.

I suggest we add documentation to wiki, readme, or identitydocs covering sovereign cloud steps / handling authority changes, etc.

I sent an email to Navya to update the documentation referred to. I also think we need to add to the wiki.

The short answer is to get the authority value from the AuthenticationResult. It will return the authority used to issue the token... not necessarily the authority where the request started.
