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.

#access to dn.base="" by * read
#access to dn.base="cn=Subschema" by * read
