Problem with setting Created, Modified, Author, Editor on file i Site Collection from Client SDK

Question

Hello,
I have a piece of code that is used for converting files from a shared file area to SharePoint for customers that move to SharePoint and Dynamics CRM. The relation to Dynamics CRM calls for using custom code an not existing conversion tools.
The code I wrote works fine if the file sent to a regular site in SharePoint, but if I try to use the same code for files in the Site Collection. If I use the address for the site collection in the constructor for the ClientContext, and the relative URL
from that for the file, both the upload and the setting of the attributes fails (I do make sure the file is there before trying to set the attributes).
After some experimentation I am able to upload the file, by creating the client context with the main site URL, and adding the site collection path elements ("/sites/crm") to the path for the file, but using the same the setting of the attributes
fails.
I have tried some other variant where the site collection elements are in the path for both the ClientContext and the file path. Then the upload fails, the file retrival (GetFileByServerRelativeUrl) works, but the retrival of the attributes then fails.
The code below illustrates the variations.
Can someone please explain what I am doing wrong, or is this a bug in the SDK?
Regards
Anders

Hello,
Thanks for your effort, but you are not addressing the problem.
As I tried to explain, setting the date works fine in the case where there is no site collection involved. There is no reason to believe that this will be different when in a site collection. Also the logon works fine in borth cases. The FieldUserValue.FromUser
can take either an email, or a prefered name. I tested both.
