2.3.15. cn=tasks

Some core Directory Server tasks can be initiated by editing a directory entry using LDAP tools. These

task entries are contained in cn=tasks. Each task can be invoked by updating an entry such as the

following:

dn: cn=task_id, cn=task_type, cn=tasks, cn=config

...

In Red Hat Directory Server deployments before Directory Server 8.0, many Directory Server tasks were

managed by the Administration Server. These tasks were moved to the core Directory Server

configuration in version 8.0 and are invoked and administered by Directory Server under the cn=tasks

entry.

There are seven tasks that are managed under the cn=tasks entry:

cn=import

cn=export

cn=backup

cn=restore

cn=index

cn=schema reload task

cn=memberof task

The common attributes for these tasks are listed in Section 2.3.15.1, “T ask Invocation Attributes for

Entries under cn=tasks”.

The cn=tasks entry itself has no attributes and serves as the parent and container entry for the

individual task entries.

IMPORTANT

Task entries are not permanent configuration entries. They only exist in the configuration file for

as long as the task operation is running or until the ttl period expires. T hen, the entry is deleted

automatically by the server.

2.3.15.1. Task Invocat ion Attribut es for Entries under cn=tasks

Five tasks which administer Directory Server instances have configuration entries which initiate and

identify individual operations. T hese task entries are instances of the same object class,

extensibleObject, and have certain common attributes which describe the state and behavior of

Directory Server tasks. The task types can be import, export, backup, restore, index, schema reload, and

memberof.

The cn attribute is used to identify a new task operation to initiate. The cn attribute value can be

anything, as long as it defines a new task.
