defined index.

Allowed At tributes

Attribute Definit ion

description Gives a text description of the entry.

nsIndexType Identifies the index type.

nsMatchingRule Identifies the matching rule.

3.4 .5.4 . nsIndexType

This optional, multi-valued attribute specifies the type of index for Directory Server operations and takes

the values of the attributes to be indexed. Each desired index type has to be entered on a separate line.

Parameter Descript ion

Entry DN cn=default indexes, cn=config, cn=ldbm

database, cn=plugins, cn=config

Valid Values

pres = presence index

eq = equality index

approx = approximate index

sub = substring index

matching rule = international index

index browse = browsing index

Default Value

Syntax DirectoryString

Example nsIndexType: eq

3.4 .5.5 . nsMat chingRule

This optional, multi-valued attribute specifies the ordering matching rule name or OID used to match

values and to generate index keys for the attribute. T his is most commonly used to ensure that equality

and range searches work correctly for languages other than English (7-bit ASCII).

This is also used to allow range searches to work correctly for integer syntax attributes that do not

specify an ordering matching rule in their schema definition. uidNumber and gidNumber are two

commonly used attributes that fall into this category.

For example, for a uidNumber that uses integer syntax, the rule attribute could be nsMatchingRule:

integerOrderingMatch.

NOTE

Any change to this attribute will not take effect until the change is saved and the index is rebuilt

using db2index, which is described in more detail in the "Managing Indexes" chapter of the

Directory Server Administrator's Guide).

Parameter Descript ion

Entry DN cn=default indexes, cn=config, cn=ldbm

database, cn=plugins, cn=config

Valid Values Any valid collation order object identifier (OID)

Default Value None

Syntax DirectoryString

Example nsMatchingRule: 2.16.840.1.113730.3.3.2.3.1 (For

Bulgarian)

3.4 .5.6 . nsSystemIndex

This mandatory attribute specifies whether the index is a system index, an index which is vital for

Directory Server operations. If this attribute has a value of true, then it is system-essential. System

indexes should not be removed, as this will seriously disrupt server functionality.
