You seem to be confusing NFS with Sun's implementation of NFS (which other vendors have picked up and are selling as part of their own product, though DEC in particular seems to have resisted). Not all NFS servers map incoming uid 0 (an old version of mine didn't). Of those that do, not all are restricted to mapping only uid 0, nor need this be done by the kernel. Not all NFS implementations have YP supplied as well. Some people don't *want* a network-wide passwd file. NFS != Sun's NFS. der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu
