I have setup the entire code as detailed in the guide. However when I hit the "All Users" api I get the following error message : Error:Authorization_RequestDenied! Insufficient privileges to complete the operation. {"odata.error":{"code":"Authorization_RequestDenied","message":{"lang":"en","value":"Insufficient privileges to complete the operation."}}}

This is the log I get in tomcat: org.sampleapp.exceptions.SampleAppException: Insufficient privileges to complete the operation.

I have given all permissions through API access to my application in Azure portal under "Required permissions". Any idea why I might be getting this error?

How does one set the thumbnailPhoto attribute of a user? The docs say "Edm.Stream" but I have no idea what that translates to for the value in JSON when doing REST. Is that a base64 encoded set of of bytes?

Please explain

Thank you for publishing this code. When trying to use the code I keep getting an error when trying to generate the access token. I suspect this is due to incorrect parameters in the web.xml file. Can you provide definition for these values? For example where do I get the TenantContextID? I used my Client ID for my application but I don't think that is correct. I think the Client ID should be AppPrincipalId, is this correct? For the symmetric key I used the key that was generated for the app in the portal which I think is correct. What is the AcsPrincipalId and the ProtectedResourcePrincipalId?

I am very happy that I found your java sample, but I am stuck (with two accounts/applications) on this error:

invalid_client","error_description":"ACS50012: Authentication failed

I know it is not your code, it works fine with the provided values, but I was hoping you could help me out.
