In order to connect to the OData source when Blackbaud hosts the database and you use AD Authentication (single sign on), the following web.config changes are required:

Under the "ODataQuery.ashx" location element, set basicAuthentication, anonymousAuthentication, and windowsAuthentication to "false".


<location path="ODataQuery.ashx">
  <system.webServer>
    <security>
      <authentication>
        <basicAuthentication enabled="false" />
        <anonymousAuthentication enabled="false" />
        <windowsAuthentication enabled="false" />
      </authentication>
    </security>
  </system.webServer>
</location>
