[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!
