Commented Issue: Adapters fail in Claims environment. [18463]

<p>When trying to connect the adapters to SharePoint lists in a SharePoint farm configured to use Claims authentication, the following error message is return when Visual Studio attempts to validate the SSIS package, and also when attempting to run the package.</p>
<p>&nbsp;</p>
<p>System.ServiceModel.Security.MessageSecurityException: The HTTP request was forbidden with client authentication scheme &#39;Ntlm&#39;. ---&gt; System.Net.WebException: The remote server returned an error: (403) Forbidden.</p>
<p>&nbsp;</p>
<p>The same package, with the adapters pointing to lists in a SharePoint farm that does not use Claims works perfectly.</p>

@vtang9 - we never resolved this is my environment. Instead we found alternatives where we did not need to connect SSIS with a Claims-only SharePoint environment. In our case, we have multiple SharePoint environments, the customer's source data was located in one using standard Windows authentication rather than Claims. Se we run the package there and then send the data to the claims environment. (Originally we were planning to migrate the customer's data and sites from the non-claims environment totally into the claims environment - but no longer)
