Configuring Cascading Chaining Using The Console; Configuring Cascading Chaining From The Command Line - Red Hat DIRECTORY SERVER 8.0 - ADMINISTRATION Administration Manual

Chapter 3. Configuring Directory Databases
3. Select the Check local ACI checkbox to enable the evaluation of local ACIs on the intermediate
database links involved in cascading chaining. Selecting this checkbox may require adding the
appropriate local ACIs to a database on the servers that contain intermediate database links.
4. Enter the maximum number of times a database link can point to another database link in the
Maximum hops field.
By default, the maximum is 10 hops. After 10 hops, a loop is detected by the server, and an error
is returned to the client application.
5. Click Save.
NOTE
Changes made to the default settings of a database link are not applied retroactively. Only
the database links created after changes are made to the default settings will reflect the
changes.

3.3.7.3. Configuring Cascading Chaining Using the Console

To configure cascading chaining for a particular set of database links, do the following:
1. In the Directory Server Console, select the Configuration tab.
2. Expand the Data folder in the left pane, and locate the database link to include in a cascading
chain. Click the database link, then click the Limits and Controls tab in the right navigation pane.
3. Select the Check local ACI checkbox to enable the evaluation of local ACIs on the intermediate
database links involved in the cascading chain. Selecting this checkbox may require adding the
appropriate local ACIs to the database link.
4. Enter the maximum number of times a database link can point to another database link in the
Maximum hops field.
By default, the maximum is ten hops. After ten hops, a loop is detected by the server, and an error
is returned to the client application.
5. Click Save.

3.3.7.4. Configuring Cascading Chaining from the Command Line

To configure a cascade of database links through the command line, do the following:
1. Point one database link to the URL of the server containing the intermediate database link.
To create a cascading chain, the nsFarmServerURL attribute of one database link must contain
the URL of the server containing another database link. Suppose the database link on the server
called example1.com points to a database link on the server called africa.example.com. For
example, the cn=database_link, cn=chaining database, cn=plugins,cn=config entry of
the database link on Server 1 would contain the following:
nsFarmServerURL: ldap://africa.example.com:389/
