Ubuntu :: Using Autofs To Wake Samba Server Over Ethernet

I'm trying to set autofs up to wake a samba file server whenever I want to use it. I found this page which apparently demonstrates how to do it with NFS. With a bit of modification I've managed to come up with this:

Code:
/etc/auto.wake
#!/bin/sh
hostsrv=<server ip address>
hostmac=<server mac address>
opts="-fstype=cifs,rw,credentials=/etc/samba/.creds"

netcat -w 5 -z $hostsrv 445
status=$?
if [ $status -ne 0 ]
then
/usr/sbin/etherwake -i $hostsrv $hostmac
sleep 60
fi

/bin/echo -n "share"
/bin/echo -n -e " "
/bin/echo -n "$opts"
/bin/echo -n -e " "
/bin/echo "://$hostsrv/share"

Now, I've added this line to auto.master

Code:
/server /etc/auto.wake --timeout=60 --ghost
and restarted autofs
Code:
sudo service autofs restart
It wakes up the server successfully but then when I wait 60 seconds and browse the /server directory on the client the share doesn't appear at all.
