opendirectoryd(8)

NAME
opendirectoryd - is a launchd(8) job for client access to local or remote directory systems

SYNOPSIS
opendirectoryd [--version]

DESCRIPTION
opendirectoryd is a launchd(8) job which replaces "DirectoryService" as a core part of the Open Directory technology. Several modules are provided that allow access to existing directory systems:

•   Active Directory
•   LDAP
•   Local Database
•   NIS

  Modules
opendirectoryd modules have specific capabilities:

Authentication
    password verification, password changes, etc.
Connection
    general connections used for queries, record modifications, etc.
Discovery
    location and prioritization of servers to contact (a.k.a., service discovery)
Unspecified
    a generic module used for unspecified purpose (usually to extend capabilities)

Third party plugins developed for "DirectoryService" are supported via dspluginhelperd(8).

  Open Directory
Open Directory is a technology which includes a client API abstraction layer, a directory server, and the opendirectoryd daemon. This allows clients to utilize a single API to access a variety of directory servers simultaneously or configure their own directory server.

Open Directory forms the foundation of how Mac OS X accesses all authoritative configuration information (users, groups, mounts, managed desktop data, etc.). This allows use of virtually any directory system via Apple and third party modules.

Configuration of opendirectoryd is done via "System Preferences" under the "Users & Groups" preference pane. Advanced settings are available by using "Open Directory Utility..." within "Users & Groups" preference pane.

More information is available from the Open Directory website:

  Open Directory Server
Open Directory Server utilizes OpenLDAP which is included as part of Mac OS X Client, Mac OS X Server, and Darwin. OpenLDAP provides a robust and scalable platform for serving directory-based information for both standalone and networked systems.

  NFSv4 Domain name
The following will set the default domain name used to map user and group identities in NFSv4 client/server operations.

    dscl . -create Config/NFSv4Domain RealName <Example.com>

This command requires root privileges.

FILES
Files are stored in various locations for opendirectoryd depending on use. A list of folders and files are shown below.

  System files provided by Apple and should only change with operating system updates:
/System/Library/OpenDirectory/Configurations/
    node configuration files
/System/Library/OpenDirectory/DynamicNodeTemplates/

    OpenDirectory global record/attribute permissions

  User defined files:
/Library/OpenDirectory/Templates/

/Library/OpenDirectory/Mappings/
    record/attribute mapping tables

  Files that change periodically are located in:
/Library/Preferences/OpenDirectory/Configurations/
    node configuration files
/Library/Preferences/OpenDirectory/DynamicData/
    dynamic data stored by nodes
/Library/Preferences/OpenDirectory/.LogDebugAtStartOnce
    enables debug logging until process exits or system is rebooted (reboot required)
