Trouble using autofs with Ubuntu 8.04

Ubuntu Users,

I'm having troubles with autofs.  I have created /etc/auto.master and /etc/
auto.net, with the following contents:

/etc/auto.master:

> #
> # $Id: auto.master,v 1.4 2005/01/04 14:36:54 raven Exp $
> #
> # Sample auto.master file
> # This is an automounter map and it has the following format
> # key [ -mount-options-separated-by-comma ] location
> # For details of the format look at autofs(5).
> #
> /misc    /etc/auto.misc
> #/net    -hosts

> #

> # nsswitch sources.

> #
> +auto.master


/etc/auto.net:

> fpga1     -rw     toast.ee.byu.edu:/fpga1
> fpga2     -rw     toast.ee.byu.edu:/fpga2
> #ee2       -rw     nfs-ee2.et.byu.edu:/ee2
>

When I check the status of autofs, I get the following:

[james at lynx:~] sudo /etc/init.d/autofs status
> Configured Mount Points:
> ------------------------
> /usr/sbin/automount --timeout=300 /misc file /etc/auto.misc
> /usr/sbin/automount --timeout=300 /net file /etc/auto.net
>
> Active Mount Points:
> --------------------
> /usr/sbin/automount --pid-file=/var/run/autofs/_misc.pid --timeout=300
> /misc file /etc/auto.misc
> /usr/sbin/automount --pid-file=/var/run/autofs/_net.pid --timeout=300 /net
> file /etc/auto.net
>
>
So, it appears to be running.  I can see toast, as demonstrated by a simple
ping:

[james at lynx:~] ping toast
> PING toast.ee.byu.edu (10.8.118.139) 56(84) bytes of data.
> 64 bytes from 10.8.118.139: icmp_seq=1 ttl=63 time=0.296 ms

> rtt min/avg/max/mdev = 0.162/0.270/0.507/0.140 ms

However, when I try to access the mount point, I get the following error:

> [james at lynx:~] cd /net/fpga1
> bash: cd: /net/fpga1: No such file or directory

I have read the autofs HOWTO, along with several posts in the Ubuntu
Forums.  Any idea what I'm doing wrong?

All of my coworkers use CentOS and autofs has never been a problem.  I am
the only Ubuntu user.

Thanks for your help,
