autofs 4.1.3 problem

Hello Everybody,
I'm having a Red Hat Enterprise 3 AS installed on one of the
system. I'm having NIS & NFS network. I usually install Autofs to
automount all the systems on my network i.e.
/hosts/<hostname>/<sharename>
Somehow on my new system i.e. RHEL 3AS this thing is not working.
I've installed Autofs 4.1.3 on this system. When I go in to
/hosts/<hostname>, I do not see any share there. What could be the
problem?

thanks,

Pranay
