Chapter 6 Managing Access Control 257
8.
To enforce SSL authentication from
HostedCompany1
administrators, switch to
manual editing by clicking the Edit Manually button. Add the following to the
end of the LDIF statement:
and (authmethod="ssl")
The LDIF statement should be similar to:
aci: (targetattr = "*")
(target="ou=HostedCompany1,ou=corporate-clients,dc=example,dc
=com") (version 3.0; acl "HostedCompany1"; allow (all)
(roledn=
"ldap:///cn=DirectoryAdmin,ou=HostedCompany1,ou=corporate-cli
ents, dc=example,dc=com") and (dayofweek="Mon,Tues,Wed,Thu")
and (timeofday >= "0800" and timeofday <= "1800") and
(ip="255.255.123.234") and (authmethod="ssl"); )

Click OK.
The new ACI is added to the ones listed in the Access Control Manager
window.
Denying Access
If your directory holds business-critical information, you might specifically want to
deny access to it.
For example,
example.com
wants all subscribers to be able to read billing
information such as connection time or account balance under their own entries
but explicitly wants to deny write access to that information. This is illustrated in
ACI “Billing Info Read” and ACI “Billing Info Deny,” respectively.
ACI “Billing Info Read”
In LDIF, to grant subscribers permission to read billing information in their own
entry, you would write the following statement:
aci: (targetattr="connectionTime || accountBalance") (version
3.0; acl "Billing Info Read"; allow (search,read) userdn=
"ldap:///self";)
This example assumes that the relevant attributes have been created in the schema
and that the ACI is added to the
ou=subscribers,dc=example,dc=com
entry.
From the Console, you can set this permission by doing the following:
