[CentOS] mod_auth_ldap Apache2 on CentOS 5 and require group

Hi , i am facing a strange problem.

I have centos , i wan to access svn trought apache using mod auth ldap.

This is what i have configured

       AuthLDAPBindDN cn=svn,ou=Operators,o=Organization
        AuthLDAPBindPassword Pass1
        AuthLDAPURL "ldap://ldap/ou=Users,o=Organization?uid"
        AuthLDAPGroupAttribute member
        AuthLDAPGroupAttributeIsDN on
        Require group cn=tester2,ou=Groups,o=Organization

What is strange?

According to doc it will accept only users which DN is in group
cn=teste2,ou=Groups,o=Organization.

How come, for me it will accept every one user from LDAP?

Thanks in advance!
