Step 2. Configure Service Access for Mobile Application
Whenever any resource e.g. web application, web service, etc. needs to be secured by Azure Active Directory, it needs to be registered. All the secure applications or services can be seen under Applications tab. Here you can select the application which needs to be accessed from mobile application and give access to it.
On the Configure tab, locate permissions to other applications section:
Click on Add application button. On the next screen pop-up you should see list of all the applications which are secured by Azure Active Directory. Select the applications that needs to be accessed from the mobile application.
After selecting the application, once again select the newly-added application in permissions to other applications section and give appropriate rights.
Finally, Save the configuration. These services should now be available in mobile applications!
