Problem with Linux >= 3.3 as NFSv4 server

[Norbert Aschendorff]

And just another thing: Using the Fedora machine (also kernel 3.5) as
server, I see the exactly same behavior. Sending '1000' (numeric UID)
instead of actual username. Using Kernel 3.2 on the server, the
translation even works when using the same username and different IDs
(as it should...).
