Typical configurations to check are:

  1. The application is running as a service
  2. The service is running as a user on the same domain as the machine
  3. The user has privileges for Kerberos delegation

To check the current privileges, run:

setspn -L username

To add privileges for the current user, run

setspn -A HTTP/machine:port username

Still Need Help?

With new versions of Internet Explorer, Firefox or Chrome, use developer tools.

With older versions of Internet Explorer, trace the HTTP request/response.

  1. Download and install IEHttpHeaders.
  2. Choose Tools, Display IEHttpHeaders.
  3. Make one request that ends up in a popup or failure.
  4. Copy the entire HTTP conversation.

Post the http conversation with your question to the Waffle Users Google Group.
