3.6. Retro Changelog Plug-in Attributes

3.6.1. nsslapd-changelogdir
3.6.2. nsslapd-changelogmaxage (Max Changelog Age)

This chapter contains reference information on Red Hat Directory Server plug-ins.

The configuration for each part of Directory Server plug-in functionality has its own separate entry and set of attributes under the subtree cn=plugins, cn=config.

dn: cn=Telephone Syntax, cn=plugins, cn=config
objectclass: top
objectclass: nsSlapdPlugin
objectclass: extensibleObject
cn: Telephone Syntax
nsslapd-pluginPath: libsyntax-plugin
nsslapd-pluginInitfunc: tel_init
nsslapd-pluginType: syntax
nsslapd-pluginEnabled: on

Some of these attributes are common to all plug-ins while others 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.

All plug-ins are instances of the nsSlapdPlugin object class, which in turn inherits from the extensibleObject object class. For plug-in configuration attributes to be taken into account by the server, both of these object classes (in addition to the top object class) must be present in the entry, as shown in the following example:

dn:cn=ACL Plugin, cn=plugins, cn=config
objectclass:top
objectclass:nsSlapdPlugin
objectclass:extensibleObject

3.1. Server Plug-in Functionality Reference

The following tables provide a quick overview of the plug-ins provided with Directory Server, along with their configurable options, configurable arguments, default setting, dependencies, general performance-related information, and further reading. These tables assist in weighing plug-in performance gains and costs and choose the optimal settings for the deployment. The Further Information section cross-references further reading, where this is available.

3.1.1. 7-bit Check Plug-in

Plug-in Parameter	Description
Plug-in Name	7-bit check (NS7bitAtt)
DN of Configuration Entry	cn=7-bit check, cn=plugins, cn=config
Description	Checks certain attributes are 7-bit clean
Configurable Options	on \| off
Default Setting	on
Configurable Arguments	List of attributes (`uid mail userpassword`) followed by "," and then suffixes on which the check is to occur.
Dependencies	None
Performance Related Information	None
Further Information	If the Directory Server uses non-ASCII characters, such as Japanese, turn this plug-in off.

3.1.2. ACL Plug-in

Plug-in Parameter	Description
Plug-in Name	ACL Plug-in
DN of Configuration Entry	cn=ACL Plugin, cn=plugins, cn=config
Description	ACL access check plug-in
Configurable Options	on \| off
Default Setting	on
Configurable Arguments	None
Dependencies	None
Performance Related Information	Access control incurs a minimal performance hit. Leave this plug-in enabled since it is the primary means of access control for the server.
Further Information	See the "Managing Access Control" chapter in the Directory Server Administrator's Guide.

3.1.3. ACL Preoperation Plug-in

Plug-in Parameter	Description
Plug-in Name	ACL Preoperation
DN of Configuration Entry	cn=ACL preoperation, cn=plugins, cn=config
Description	ACL access check plug-in
Configurable Options	on \| off
Default Setting	on
Configurable Arguments	None
Dependencies	Database
Performance Related Information	Access control incurs a minimal performance hit. Leave this plug-in enabled since it is the primary means of access control for the server.
Further Information	See the "Managing Access Control" chapter in the Directory Server Administrator's Guide.

3.1.4. Attribute Uniqueness Plug-in

Plug-in Parameter	Description
Plug-in Name	Attribute Uniqueness Plug-in
DN of Configuration Entry	cn=Attribute Uniqueness, cn=plugins, cn=config
Description	Checks that the values of specified attributes are unique each time a modification occurs on an entry. For example, most sites require that a user ID and email address be unique.
Configurable Options	on \| off
Default Setting	off
Configurable Arguments	To check for UID attribute uniqueness in all listed subtrees, enter `uid "DN" "DN"...`. However, to check for UID attribute uniqueness when adding or updating entries with the `requiredObjectClass`, enter `attribute="uid" MarkerObjectclass = "ObjectClassName"` and, optionally `requiredObjectClass = "ObjectClassName"`. This starts checking for the required object classes from the parent entry containing the ObjectClass as defined by the `MarkerObjectClass` attribute.
Dependencies	Database
Performance Related Information	Directory Server provides the UID Uniqueness Plug-in by default. To ensure unique values for other attributes, create instances of the Attribute Uniqueness Plug-in for those attributes. See the "Using the Attribute Uniqueness Plug-in" in the Directory Server Administrator's Guide for more information about the Attribute Uniqueness Plug-in. The UID Uniqueness Plug-in is off by default due to operation restrictions that need to be addressed before enabling the plug-in in a multi-master replication environment. Turning the plug-in on may slow down Directory Server performance.
Further Information	See the"Using the Attribute Uniqueness Plug-in" in the Directory Server Administrator's Guide.

Further Information	See the "Using the Pass-through Authentication Plug-in" chapter in the Directory Server Administrator's Guide.

3.1.30. Referential Integrity Postoperation Plug-in

Plug-in Parameter Description

Plug-in Name Referential Integrity Postoperation

DN of Configuration Entry cn=Referential Integrity Postoperation, cn=plugins, cn=config

Description Enables the server to ensure referential integrity

Configurable Options All configuration and on | off

Default Setting off

Configurable Arguments

When enabled, the post-operation Referential Integrity Plug-in performs integrity updates on the member, uniquemember, owner and seeAlso attributes immediately after a delete or rename operation. The plug-in can be reconfigured to perform integrity checks on all other attributes:

Check for referential integrity.

-1= no check for referential integrity

0= check for referential integrity is performed immediately

Positive integer= request for referential integrity is queued and processed at a later stage. This positive integer serves as a wake-up call for the thread to process the request at intervals corresponding to the integer (number of seconds) specified.

Log file for storing the change; for example /var/log/dirsrv/slapd-instance_name/referint.
All the additional attribute names to be checked for referential integrity.

Dependencies Database

Performance Related Information The Referential Integrity Plug-in should be enabled only on one master in a multimaster replication environment to avoid conflict resolution loops. When enabling the plug-in on chained servers, be sure to analyze the performance resource and time needs as well as integrity needs; integrity checks can be time consuming and demanding on memory and CPU. All attributes specified must be indexed for both presence and equality.

Further Information See the "Managing Indexes" chapter for information about how to index attributes used for referential integrity checking and the "Configuring Directory Databases" chapter in the Directory Server Administrator's Guide.

3.1.31. Retro Changelog Plug-in

DN of Configuration Entry	cn=Retro Changelog Plugin, cn=plugins, cn=config
Description	Used by LDAP clients for maintaining application compatibility with Directory Server 4.x versions. Maintains a log of all changes occurring in the Directory Server. The retro changelog offers the same functionality as the changelog in the 4.x versions of Directory Server. This plug-in exposes the `cn=changelog` suffix to clients, so that clients can use this suffix with or without persistent search for simple sync applications.
Configurable Options	on \| off
Default Setting	off
Configurable Arguments	See Section 3.6, “Retro Changelog Plug-in Attributes” for further information on the two configuration attributes for this plug-in.
Dependencies	None

Further Information	This plug-in enables the Directory Server to support `space and case insensitive` values. Applications can now search the directory using entries with ASCII space characters. For example, a search or compare operation that uses `jOHN Doe` will match entries that contain `johndoe`, `john doe`, and `John Doe` if the attribute's schema has been configured to use the space insensitive syntax. For more information about finding directory entries, refer to the "Finding Directory Entries" Appendix in the Directory Server Administrator's Guide.
