How to update the values of Editor or Author fields in a SharePoint list (not a document library) item via web services?
I did read somewhere that updating the fields would be possible for lists (but not for document libraries).
For example, I have understood that it should be possible to update a listitem via Lists.asmx / UpdateListItems and passing Editor and Author fields as ID;#AccountName (15;#DEV\User)
However I don't seem to get this to work. Any ideas?
