The warning you saw "non-matching-uid symlink following attempted in sticky world-writable directory by mount.nfs4 (fsuid 0 != 1000)" should only happen in the case where a symlink is being following in a directory that is world-writable and sticky ("+t"). None of your directories seem to have that, though.
