Accessing and Modifying Server Configuration

Some of these attributes are common to all plug-ins, and some may be particular to a specific plug-in.
Check which attributes are currently being used by a given plug-in by performing an ldapsearch on
the cn=config subtree.
For a list of plug-ins supported by Directory Server, general plug-in configuration information, the plug-
in configuration attribute reference, and a list of plug-ins requiring restart for configuration changes,
see Chapter 3, Plug-in Implemented Server Functionality Reference.
2.1.2.3. Configuration of Databases
The o=NetscapeRoot and cn=UserRoot subtrees under the database plug-in entry contain
configuration data for the databases containing the o=NetscapeRoot suffix and the default suffix
created during setup, such as dc=example,dc=com.
These entries and their children have many attributes used to configure different database settings,
like the cache sizes, the paths to the index files and transaction logs, entries and attributes for
monitoring and statistics; and database indexes.
2.1.2.4. Configuration of Indexes
Configuration information for indexing is stored as entries in the Directory Server under the following
information-tree nodes:
• cn=index,o=NetscapeRoot,cn=ldbm database,cn=plugins,cn=config
• cn=index,cn=UserRoot,cn=ldbm database,cn=plugins,cn=config
• cn=default indexes,cn=config,cn=ldbm database,cn=plugins,cn=config
For more information about indexes in general, see the Directory Server Administrator's Guide. For
information about the index configuration attributes, see Section 3.4.1, “Database Attributes under
cn=config, cn=ldbm database, cn=plugins, cn=config”.
2.2. Accessing and Modifying Server Configuration
This section discusses access control for configuration entries and describes the various ways in
which the server configuration can be viewed and modified. It also covers restrictions to the kinds
of modification that can be made and discusses attributes that require the server to be restarted for
changes to take effect.
2.2.1. Access Control for Configuration Entries
When the Directory Server is installed, a default set of access control instructions (ACIs) is
implemented for all entries under cn=config. The following code sample is an example of these
default ACIs.
aci: (targetattr = "*")(version 3.0; acl "Configuration Administrators Group"; allow (all)
groupdn = "ldap:///cn=Configuration Administrators,u=Groups, ou=TopologyManagement,
o=NetscapeRoot";)
aci: (targetattr = "*")(version 3.0; acl "Configuration Administrator"; allow (all)
userdn = "ldap:///uid=admin, ou=Administrators, ou=TopologyManagement, o=NetscapeRoot";)
aci: (targetattr = "*")(version 3.0; acl "Local Directory Administrators Group"; allow (all)
groupdn = "ldap:///ou=Directory Administrators, dc=example,dc=com";)
