   Now that YP is running, csh exhibits the following bizarre behavior:

   % cd
   % ls | cat > ~luser/a
   cat: read error: Bad file number
   %

   (where the current user is in fact "luser".

   The following does what you would expect:

   % cd
   % ls | cat > ~/a
   %

   Any clues?

I'm a little slow in catching up...

I suggest you try a few experiments with getpwnam.  I suspect that
what is happening is something like the [t]csh calling getpwnam, which
happily goes out and does a yp call, and low and behold there is no
user named "luser" in the yp password file, so the routine happily
reports a failure to the shell, but you were able to log in which
means that login(1) probabibly uses an older/ypless version of
getpwnam, so it succeeds in reading from /etc/passwd.

BTW, if anybody has a compiled and working version of a recent tcsh 
for Umax 4.3 with YP I'd like to hear about it/get your diffs/ftp a copy.
