NIS authentication problems

Hi,

I'm trying to set up NIS with the simplest setup: one server and one
client. I've followed the procedure in the handbook, altering
{login,auth}.conf as suggested (BTW: how do I know what format are my
passwords stored in?). ypcat passwd shows me the user list, but I can't
log in (Login incorrect).

What am I doing wrong or what could I be missing?
How can I debug this?

tks
