PSIcapture Migration: SharePoint Error: The HTTP request is unauthorized with client authentication scheme 'NTLM'

Problem:

When attempting to migrate to SharePoint, PSIcapture displays the following error, replicated in the log:

[8/20/2013 9:35:53 AM - Error - v4.6.0.26] 
The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'NTLM'.

Solution:

This error has to do with Permissions not being correct for the user credentials entered within the SharePoint Migration configuration.

Check the SharePoint Permissions List to ensure the user meets the criteria.
