subversion acls

Hi,
     I am new to subversion. I am trying to set up directory-level
access control in the repository. The 'conf/authz' is as follows:
[/]
* = r

[/abc/trunk/src]
* =
user1 = rw

But when I try to checkout the source as the user 'user1', I get the
following error:
"svn: Not authorized to open root of edit operation"
What am I doing wrong here ?

Regards,

-Rahul S.
