This is just a follow-on question regarding this, I don't have any answers (yet). I just discovered that under 0.9 and 0.9-current I can't run xterms anymore that need to access the .Xauthority file via NFS. I have no Idea whether this worked under 0.8 or, for that matter, under 386BSD. I'll whip up a test program shortly, but it sure seems like a suid-root program that changes its id to that of the original user can't access that user's private files over NFS. -- Tim Chase Introl Corp.
