It's a libc5 Sackware box (I'm not sure what Slackware version, but I
checked that it's libc5). Yes - the output of "ypcat passwd" there is
Now I'm sure that the problem is with shadow - I ltraced login, and
saw that it crypts the password I enter with the "##" salt, and then
compares it to the "##username" string it got from getpwent() as the
password. Therefore, it doesn't even look for a shadow password. The
machine uses shadow passwords for the root & local accounts. I thought
that maybe it would look for a shadow password if the password was "x"
and not the "##username" thing, so I changed the last line in
/etc/passwd to "+:x:::::", but <sigh> as always that didn't help.

No. (No such map...) But I also can't do it from any other box that
already is using NIS successfully, such as our SunOS and Solaris
boxes! I checked and the map _is there_, and there's indeed no
shadow.byname map. AAACK!
