Root privileges don't generally extend over NFS. I've noticed a problem with NFS being restricted by the permissions of of the mount point. The problem and fix went something like this: login: pdf Password: getwd: can't stat . Logging in with HOME="/" $ cd ~pdf $ /bin/pwd /nfs/hostname/users/pdf $ cd / $ su Password: # umount /nfs/hostname/users # ls -ld /nfs/hostname total 1 drwxr-x--- 2 root system 512 Dec 16 11:31 users # chmod a+rx /nfs/hostname/users # mount /nfs/hostname/users # exit $ exit login: pdf Password: $ /bin/pwd /nfs/hostname/users/pdf $ The systems involved ran SUNos and MIPS/os.
