How to give access control to subdirectories in my repository?

Hi all,
This is the first time for me to use SVN.
i m using subversion 1.4.3, with svnserve & TortoiseSVN.

My problem is: I cant make access control on a subdirectory in my
repository.

suppose that my repository Layout is as follows:
/calc/trunk/subfolder1
 /calc/trunk/subfolder2

Also Assume that i have 2 users:(user1,user2). I want to give user1
read/write access to subfolder1 while user2 should have read access to this
subfolder1

SO i adjust the authz-db = authz in the configuration file of the server
where it looks like this:

[groups]
my_group = user1,user2

[/trunk/subfolder1]
user1 = rw
user2 = r

the authorization failed if i tried to commit anything.

i have searched the forum & found this thread

http://svn.haxx.se/users/archive-2006-04/1038.shtml

But i still dont know how to solve this Bug?

thanks in advance
