OK, did some investigation here, I tried to connect to my home share on 
a machine running Linux MInt 17 from another machine running debian 
wheezy, I also created a simple script to echo something to /tmp. 
[homes] on the mint machine looks like this:

[homes]
    comment = Home Directories
    browseable = yes
    read only = no
    root preexec = /usr/local/scripts/welcome.sh %U

The script:

#!/bin/bash

SAMBAUSER=$1

echo "Welcome ${SAMBAUSER}" > /tmp/welcome.txt

exit 0

When I tried to browse to [homes], it showed in Caja, but would not let 
me enter to get to my home share and nothing appeared in /tmp

I changed [homes] to [home] , added the line 'path = /home', restarted 
everything and tried again, this time I could enter the 'home' share and 
the 'welcome.txt' file was created in /tmp.
I then changed 'browseable = yes' to 'browseable = no', removed the txt 
file in /tmp, restarted samba and then browsed directly to my home 
share, again it worked and the txt file was created in /tmp
