Problem with svnserve.conf

Hi,

I installed subversion in a Linux server and I'm using it with Tortoise. I
did a configuration to work with authz file as I show bellow:

#svnserve.conf file
[general]
anon-access = read
auth-access = write
password-db = passwd
authz-db = authz
realm = embraer

#authz file
[group]
gsw_desenv = rsilva
gsw_cord = debora

[/]
@gsw_cord = rw
* = r

#passwd file
[users]
rsilva = rsilva1
debora = dferrara1
valeria = valeria1

The problem is that users valeria and rsilva are allowed to commit files
and folders with Tortoise even if they don't have authorization to do it.
I think that svnserve.conf file is not recognizing authz file. All
configuration files are in the conf path of the repository.

I will appreciate some help.
