2.1.3.2. Adding the Custom Distribution Function to a Suffix Using the

Command-Line

1. Run ldapmodify.

ldapmodify -p 389 -D "cn=directory manager" -w secret -h us.example.com

2. Add the following attributes to the suffix entry itself, supplying the information about the

custom distribution logic:

nsslapd-backend: Database1

nsslapd-backend: Database2

nsslapd-backend: Database3

nsslapd-distribution-plugin: /full/name/of/a/shared/library

nsslapd-distribution-funct:distribution-function-name

The nsslapd-backend attribute specifies all of the databases associated with this suffix. The

nsslapd-distribution-plugin attribute specifies the name of the library that the plug-in

uses. The nsslapd-distribution-funct attribute provides the name of the distribution

function itself.

For more information about using the ldapmodify command-line utility, see Section 2.4,

“Adding and Modifying Entries Using ldapmodify”.

• Section 2.2.2, “Deleting a Database”

• Section 2.2.3, “Configuring Transaction Logs for Frequent Database Updates”

When a database is in read-only mode, you cannot create, modify, or delete any entries. One of

the situations when read-only mode is useful is for manually initializing a consumer or before

backing up or exporting data from the Directory Server. Read-only mode ensures a faithful

image of the state of these databases at a given time.

The Directory Server Console and the command-line utilities do not automatically put the

directory in read-only mode before export or backup operations because this would make your
