Creating and Maintaining Database Links
Chapter 3 Configuring Directory Databases 101
After allowing the component to chain, you must create an ACI in the suffix on the
remote server to which the operation will be chained. For example, you would
create the following ACI for the referential integrity component:
aci: (targetattr
"*")(target="ldap:///ou=customers,l=us,dc=example,dc=com")
(version 3.0; acl "RefInt Access for chaining"; allow
(read,write,search,compare) userdn = "ldap:///cn=referential
integrity postoperation,cn=plugins,cn=config";)
Chaining LDAP Controls
You can choose to not chain operation requests made by LDAP controls. By
default, requests made by the following controls are forwarded to the remote
server by the database link:
• Virtual list view (VLV)—This control provides lists of parts of entries rather
than returning all entry information.
• Server side sorting—This control sorts entries according to their attribute
values.
• Managed DSA—This controls returns smart referrals as entries rather than
following the referral. This allows you to change or delete the smart referral
itself.
• Loop detection—This control keeps track of the number of times the server
chains with another server. When the count reaches a number you configure, a
loop is detected and the client application is notified. For more information
about using this control, refer to “Detecting Loops,” on page 128.
The following sections describe how to alter the controls that the database link
forwards using the console and from command line.
Chaining LDAP Controls Using the Console
1.
On the Directory Server Console, select the Configuration tab.
2.
Expand the Data folder in the left pane and click Database Link Settings.
NOTE Server side sorting and VLV controls are supported only when a
client application request is made to a single database. Database
links cannot support these controls when a client application makes
a request to multiple databases.
