3.3.2.2. Creating a Database Link from the Command Line

1. Use the ldapmodify command-line utility to create a new database link from the command line.
The new instance must be located in the cn=chaining database,cn=plugins,cn=config
entry.
ldapmodify -a -p 389 -D "cn=directory manager" -w secret -h us.example.com
2. Specify the configuration information for the database link:
dn: cn=examplelink,cn=chaining database,cn=plugins,cn=config
objectclass: top
objectclass: extensibleObject
objectclass: nsBackendInstance
nsslapd-suffix: ou=people,dc=example,dc=com suffix being chained
nsfarmserverurl: ldap://people.example.com:389/
nsmultiplexorbinddn: cn=proxy admin,cn=config bind DN
nsmultiplexorcredentials: secret bind password
cn: examplelink
Default configuration attributes are contained in the cn=default config, cn=chaining
database,cn=plugins,cn=config entry. These configuration attributes apply to all database
links at creation time. Changes to the default configuration only affect new database links. The default
configuration attributes on existing database links cannot be changed.
Each database link contains its own specific configuration information, which is stored with the
database link entry itself, cn=database_link, cn=chaining database,cn=plugins,cn=config.
For more information about configuration attributes, refer to the Directory Server Configuration,
Command, and File Reference.

3.3.2.2.1. Providing Suffix Information
Use the nsslapd-suffix attribute to define the suffix managed by the database link. For example,
for the database link to point to the people information for a remote site of the company, enter the
following suffix information:
nsslapd-suffix: l=Zanzibar,ou=people,dc=example,dc=com
The suffix information is stored in the cn=database_link, cn=chaining
database,cn=plugins,cn=config entry.
