Your problem is that login checks /etc/passwd first, before checking with
YP. What you need to do is create a file /etc/yppasswd for all the accounts,
except root and other admin stuff. Edit /etc/yp/Makefile so that it uses
/etc/yppasswd instead. Oh, and you'll probably have to put a magic cookie at
the tail of /etc/passwd to enable YP lookups. I could not find reference to
this in the Sequent doc's I checked but it's probably the same as Sun's.

Sorry, I have not done this myself and can't provide a patch. Our system
has only 100 or so users and login is quite fast.
