Hi Joe Gill,

Can you tell us what SharePoint resource you are trying to access to (i.e what is your REST call) and what permissions you've set for your AAD app? It can be simply a normal behavior due to insufficient permissions.

Hi Franck,

I gave the application rights as follows in Azure AD. Just trying to go a GET to read items

Is it possible to use ADAL for server to server authentication to SharePoibt online?

Thanks

Joe

  Yes it is possible to use ADAL for server-to-server authentication using app-only access. However, you will need a certificate to get it work with Azure AD. More info https://docs.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly& https://docs.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azuread.
  
  This is why you get a 401 status because you don't have one.

    Joe Gill Do you still have issues with this? Did you try the certificate approach?
    
    Thanks!
