You don't have an entry in the local passwd file for your account before
   this line, rigth ? If so, it will take the local entry first.

No, there are no user entries before the YP line.

   Change are propagated by running 'make' in /var/yp on the server.
   Maybe there has been an error here ? What does a 'cd /var/yp; make' (as
   root on the server) do ?

It reports pushing a bunch of maps.

Do I have to run ypserv (in slave mode) on all my non-master machines?
Should the setup look like:

       master		slave
       ------		-----
       ypserv		ypserv (slave)
       ypbind		ypbind
       rpc.yppasswdd

If so, should the slave ypbind be pointed to the slave ypserv or to
the master ypserv in /var/yp/binding/domain?

Thanks again for your help.

Cheers,
Brook
