----------------------------------------

Created a branch, CONNECTORS-572, where I intend to check in a stop-gap workaround for the issue, to see if we've got it right on site.

> The SharePoint connector does not always authenticate against the SharePoint instance.  The problem may be a bug in commons-httpclient, and a corresponding problem in httpcomponents/httpclient, where the NTLM Type-2 response user name is not the same as the NTLM Type-3 message user name.  In particular, we've seen "administrator" be passed in in the Type 1 message, and "\administrator" come back in the Type 2 response, and if "administrator" is passed in again in the Type 3 message, authentication fails.
