----------------------------------------
I think there are indeed flag issues. The following document is very helpful:

It shows that we are sending along data but not including the appropriate flags
that indicate that is what we are doing.

> Key: CONNECTORS-572
> URL: https://issues.apache.org/jira/browse/CONNECTORS-572
> Project: ManifoldCF
> Issue Type: Bug
> Components: SharePoint connector
> Affects Versions: ManifoldCF 1.0, ManifoldCF 1.0.1
> Reporter: Karl Wright
> Assignee: Karl Wright
> Fix For: ManifoldCF 1.1
>
>
> 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.
