I have security=share, and Yes I meant 'see' the share. browseable=no takes 
care of that.

Ok, I think I understand now. You were smbmounting the windows boxes on your 
linux box and then from your linux box using the cli to do what you needed 
to do on the windows shares, right? I'm no expert on this, but I think you 
have found also found the answer, "So if I run the script as $USER=root I'm 
root". From man smbmount:

 username=<arg>
              specifies the username to connect as. If this is not given, 
then
              the  environment  variable   USER  is used. This option can 
also
              take the form "user%password" or "user/workgroup" or 
"user/work-
              group%password" to allow the password and workgroup to be 
speci-
              fied as part of the username.

So what you want is: smbmount //tillie/all  /mnt/tillie -o username=root; 
which I presume you would have to be root to do. Using su to execute some 
commands has always been problematic where the command being issues relies 
on evironment variables. cron is a good example. I think the user 
environment as seen by smbmount was what was biting you in this case. Others 
with far more knowledge than I may want to weigh in or add more detail if 
required.
