How to identify account username/userid when connected to a sharepoint list
 

Hi All

Is there a way to identify with VBA the Sharepoint userid of a user
when he/she is connected to a sharepoint list? I know how to retrieve
in VBA the network's userid but this could differ from the Sharepoint
one if the user logs on to the site from a different network domain,
hence need to find out their sharepoint username/userid.

Systems: Excel 2003, Windows XP, SharePoint 2003
