        • uid=jimsmith
      • ou=Groups
        • cn=group1
        • cn=group2

Attributes

Root

Server metadata:

  • objectClass: top
  • supportedLdapVersion: 3
  • supportedSASLMechanism: EXTERNAL, PLAIN
  • supportedExtension: 1.3.6.1.4.1.1466.20037 (StartTLS)
  • subschemaSubentry: cn=subschema

​Subschema

A machine-readable definition of the LDAP server schema:

  • objectClass: top, subschema
  • objectClasses: descriptions of the supported object classes
  • attributeTypes: descriptions of the supported attribute types
  • matchingRules: descriptions of the supported matching rules

Domain

Domain that you used to enroll in Google Workspace or Cloud Identity Premium. It contains subdomains, users, groups, and organizational units.

  • objectClass: top, domain, dcObject
  • dc: the name of the domain component (ex: dc=google)
  • hasSubordinates: TRUE

​Organizational Unit

This is an organizational unit within the directory tree. The organizational unit may contain other organizational units and/or people within it. The organizational unit tree is the same as the organizational unit tree that you see in the Google Admin console.

  • objectClass: top, organizationalUnit
  • ou: the name of the organizational unit (ex: ou=Users)
  • description: the longer human-readable description of the organizational unit
  • hasSubordinates: TRUE

Person

A user in the domain. People appear under the organizational units that they belong to:

  • objectClass: top, person, organizationalPerson, inetOrgPerson, posixAccount
  • uid: The user’s username. The username portion of their email address.
  • googleUid: The same as the uid. This exists to unambiguously distinguish it from the posixUid.
  • posixUid: The user’s username or, if it is set, the user’s POSIX username.
  • cn: The “common name”. This contains two values: the user’s username and the user’s display name.
  • sn: The user’s surname.
  • givenName: The user’s given name.
  • displayName: The user’s display name (full name).
  • mail: The user’s email address.
  • memberOf: A list of the fully qualified names of groups to which this user belongs.
  • title: The user’s title.
  • employeeNumber: The user’s employee ID.
  • employeeType: The user’s role in the organization.
  • departmentNumber: The name of the user’s department. This is not necessarily a number.
  • physicalDeliveryOfficeName: The user’s location or address.
  • jpegPhoto: The user’s profile photo.
  • entryUuid: A universally unique stable identifier for this user.
  • objectSid: A universally unique identifier for this user, compatible with Windows security identifiers.
  • uidNumber: A POSIX UID number for the user. If a POSIX ID is set for the user, it will reflect that. If not, it will be a unique stable identifier.
  • gidNumber: A POSIX GID number for the user’s primary group. If a POSIX GID is set for the user, it will reflect that. If not, it will be the same as the user’s UID number.
  • homeDirectory: The user’s POSIX home directory. Defaults to “/home/<username>”.
  • loginShell: The user’s POSIX login shell. Defaults to “/bin/bash”.
  • gecos: GECOS (historical) attributes for the user.
  • hasSubordinates: FALSE

​Group

  • objectClass: top, groupOfNames, posixGroup
  • cn: The group’s domain-unique name.
  • displayName: The group’s human-readable display name.
  • description: A longer human-readable description of the group.
  • gidNumber: The POSIX GID number for the group. This is a stable unique ID, but the group cannot be efficiently looked up by it.
  • entryUuid: A universally unique stable identifier for this group.
  • objectSid: A universally unique identifier for this group, compatible with Windows security identifiers.
  • member: A list of fully qualified names of members of this group.
