2.3.15.6. cn=index

Directory attributes can be indexed though the command line by creating a special task entry which
defines the parameters of the task and initiates the task. As soon as the task is complete, the task entry
is removed from the directory.

The cn=index entry is a container entry for index task operations. The cn=index entry itself has no
attributes, but each of the task entries within this entry, such as cn=task_ID, cn=index, cn=tasks,
cn=config, uses the following attributes to define the backup task.

An index task entry under cn=index can create a standard index by identifying the attribute to be
indexed and the type of index to create, both defined in the

nsIndexAttribute

attribute.

Alternatively, the index task can be used to generate virtual list view (VLV) indexes for an attribute using
the

nsIndexVLVAttribute

attribute. This is the same as running the vlvindex script.

For example:

dn: cn=example presence index, cn=index, cn=tasks, cn=config
objectclass: extensibleObject
cn: example presence index
nsIndexAttribute: "cn:pres"

dn: cn=example VLV index, cn=index, cn=tasks, cn=config
objectclass: extensibleObject
cn: example VLV index
nsIndexVLVAttribute: "by MCC ou=people,dc=example,dc=com"

As the index operation runs, the task entry will contain all of the server-generated task attributes listed in

Section 2.3.15.1, “Task Invocation Attributes for Entries under cn=tasks”

.

nsIndexAttribute

This attribute gives the name of the attribute to index and the types of indexes to apply. The format of
the attribute value is the attribute name and a comma-separated list of index types, enclosed in double
quotation marks. For example:

nsIndexAttribute: attribute:index1,index2

Parameter

Description

Entry DN

cn=task_name, cn=index, cn=tasks, cn=config

Valid Values

Any attribute

The index type, which can be pres (presence),
eq (equality), approx (approximate), and sub
(substring)

Default Value
