I am writing a script which basically (simply put) lists the logged-on user's azure subscriptions. I'm starting by authenticating to "https://login.windows.net/common/oauth2/authorize" using adal. From there, I get a list of the tenants this user is a member of by hitting https://management.azure.com/tenants. This works fine. Then I need to log in to each of these tenants to list the subscriptions inside them.
My question: Is there a way using adal to say "I'm already logged in to login.windows.net, please automatically log me in to tenant xyz"? Or do I need to call acquiretoken(with the same creds as the first call to login.windows.net) explicitly for each tenant the user is member of?
