I have a High Trust Provider hosted app using the configuration and claims helper from this blog post .

The app can authenticate as app only but when I pass in the user information I get "There was an error: Access denied. You do not have permission to perform this action or access this resource. " The SharePoint logs show that my user is being resolved as the windows user not the SAML user. This is further proven by if I add the windows account the app will authenticate and provide me the user context. What am I doing wrong?

JWT token:

{
    "upn": "dpalfery@ssolab.local", 
    "nii": "trusted:adfs", 
    "aud": "00000003-0000-0ff1-ce00-000000000000/portal.ssolab.local@ab32783d-87a4-4705-ba23-ae2ec8134272",

    "exp": "1395592109", 
    "actortoken": "<decoded below>", 
    "nbf": "1395591509"
}

    "iss": "8a7656d9-a909-4304-9c3f-0320b175015e@ab32783d-87a4-4705-ba23-ae2ec8134272",

}

You didn't specify enough info to be 100% sure, but it is likely one of the following:

  • Need to specify -IsTrustBroker when creating the SPTrustedSecurityTokenIssuer
  • User is not found in the user profile application (discussed in Steve's post)
  • The identity claim is not unique in the user profile application. (Steve explicitly calls this out -- cannot have both claim user and windows user.)
