Use SSIS to read files in SharePoint library

Question

Hi,
I'm trying to use SSIS to read data from an Excel file in a SharePoint document library and I am having some problems with it.
First I tried to use the Excel file as a source file in an Excel Source task which worked well in BIDS but not on the SQL server. ("CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER")
Next I tried to read data from an Excel file on the SQL server file system which worked well on the SQL server.
Next I tried to use a File System Task to copy the Excel file to the SQL server file system. This also worked well in BIDS but not on the SQL server. ("The file name \\sharepoint\mylibrary\myfile.xls specified in the connection was not valid.")
I have also tried to let the SQL server agent run on a domain account that is set up as a reader on the SharePoint document library without success.
Where am I going wrong?

I was playing around with the same issue. In my case SSIS and SharePoint run on the same server.
In the IIS Log I noted that requests to the SharePoint library are made without credentials. This returns HTTP 404.
I enabled anonymous access to the SharePoint Site and this Library without any change.
IIS Log:

Using the solution by Jason solved this: http://social.msdn.microsoft.com/Forums/en/sqlintegrationservices/thread/aea4a334-bc13-4fd2-aa59-6d31dfcc45e2
In my SSIS Control Flow I run a Execute Process Task calling Net.exe with Params "Use \\share\folder password /User:domain\user /PERSISTENT:Yes" command before the file task. On the file connection I set DelayValidation to true.
