Hi,

Just set up openldap on my CentOS 6.5. Looks like very easy to set up. And it is working. However, I found ACL doesn't work as expected. I am trying to disable read access to anonymous, and give userPassword write access to self and binduser. But it doesn't work: anonymous can still read whole ldap entries, and no one except cn=Manager,dc=domain,dc=com can change userPassword. I even change following section to access to * by * none to lock down ldap, but still anonymous can read all.

=== access to dn.base="" by * read access to dn.base="cn=Subschema" by * read access to attrs=userPassword by self write by dn.exact="cn=binduser,dc=domain,dc=com" write by users read by anonymous auth

access to * by users read by anonymous auth === to === access to * by * none ===

Here is the complete slapd.conf. Look like only default ACL works, whatever ACL policy I am trying to apply. Please help.
