We have an OnPremise Environment for SharePoint 2013. where we have created SharePoint hosted app which calls "http://<appweburl>/_api/SP.UserProfiles.PeopleManager/GetMyProperties" to get current user's data but this gives me 401 unauthorized error. Notes:

  1. I had given read permission to user profile and full control to sitecollection in appmanifest. If I run this app on Office 365 developer site it works fine, but on premise environment it give 401 error.
  2. On premise environment when I deploy this app 3 times it prompt for credential and finally gives the following error

Message from webpage

{"error":{"code":"-2147024891, System.UnauthorizedAccessException","message":{"lang":"en-US","value":"Access denied. You do not have permission to perform this action or access this resource."}}}

Any help will be appreciated.

Office 365 and on-premises farms use different authentication mechanisms for provider-hosted apps. It appears that you haven't properly configured the trust relationship for your app in the on-premises farm. Here are a couple resources that should help you understand the different authentication mechanisms and perform the required configuration.

  • Thanks for reply. Ours is SharePoint Hosted App not Provider Hosted App. To make it simple i am deploying my SharePoint hosted app from Visual Studio and it is being trusted properly but after that when it redirects to the default page there i am getting the error. Does it can have any issue with AppDomain. from browser if request "http://<sitecollection>/_api/SP.UserProfiles.PeopleManager/GetMyProperties" i am getting the data but from app url "http://<app-url>/_api/SP.UserProfiles.PeopleManager/GetMyProperties" it gives the issue

  • Hmmm... that seems odd. The only thing I can think of is that your on-premises farm is not properly configured for Apps. Do you have other Apps running there? May 1, 2014 at 11:44
  • Yep Rob, I have Provider Hosted hosted with self signed certificate and its running fine without any error. Dont know what to do ?. still struggling.
