Error NFS4_BADOWNER when NFSv4 client passes UID as string
NFSv4 specifies users and groups as strings instead of the 32-bit numeric
values used by NFSv2 and v3. However, when an NFSv4 client passes the
UID as a string instead of the format user_name@domain_name, the NFSv4
server returns the error NFSV4_BADOWNER when setting file attributes and user
nobody (65534) when obtaining file attributes.
