Connecting to a sharepoint

I’ve been looking for an answer in this forum but I didn’t understand.
I’m trying to access to an xls file which is in a sharepoint. The problem is the access is secured and even tho I enter the url of the sharepoint I get a 403 ERROR using the generic web service client node.
Is there any other way to get this file? and what should I actually enter in all the dialog’s blanks.
I’m new to KNIME and I don’t know how to do that.
Please, any information would be helpful.
Thank you
