红帽全球峰会第 9 章 Using ldapmodify to manage IdM users externally
As an IdM administrators you can use the ipa commands to manage your directory content. Alternatively, you can use the ldapmodify command to achieve similar goals. You can use this command interactively and provide all the data directly in the command line. You also can provide data in the file in the LDAP Data Interchange Format (LDIF) to ldapmodify command.
9.1. Templates for managing IdM user accounts externally
The following templates can be used for various user management operations in IdM. The templates show which attributes you must modify using ldapmodify to achieve the following goals:
- Adding a new stage user
- Modifying a user’s attribute
- Enabling a user
- Disabling a user
- Preserving a user
The templates are formatted in the LDAP Data Interchange Format (LDIF). LDIF is a standard plain text data interchange format for representing LDAP directory content and update requests.
Using the templates, you can configure the LDAP provider of your provisioning system to manage IdM user accounts.
- Templates for adding a new stage user
A template for adding a user with UID and GID assigned automatically. The distinguished name (DN) of the created entry must start with
uid=user_login:dn: uid=user_login,cn=staged users,cn=accounts,cn=provisioning,dc=idm,dc=example,dc=com changetype: add objectClass: top objectClass: inetorgperson uid: user_login sn: surname givenName: first_name cn: full_nameA template for adding a user with UID and GID assigned statically:
dn: uid=user_login,cn=staged users,cn=accounts,cn=provisioning,dc=idm,dc=example,dc=com changetype: add objectClass: top objectClass: person objectClass: inetorgperson objectClass: organizationalperson objectClass: posixaccount uid: user_login uidNumber: UID_number gidNumber: GID_number sn: surname givenName: first_name cn: full_name homeDirectory: /home/user_loginYou are not required to specify any IdM object classes when adding stage users. IdM adds these classes automatically after the users are activated.
- Templates for modifying existing users
- Modifying a user’s attribute:
dn: distinguished_name changetype: modify replace: attribute_to_modify attribute_to_modify: new_valueDisabling a user:
dn: distinguished_name changetype: modify replace: nsAccountLock nsAccountLock: TRUEEnabling a user:
dn: distinguished_name changetype: modify replace: nsAccountLock nsAccountLock: FALSE
Updating the
nssAccountLockattribute has no effect on stage and preserved users. Even though the update operation completes successfully, the attribute value remainsnssAccountLock: TRUE.Preserving a user:
dn: distinguished_name changetype: modrdn newrdn: uid=user_login deleteoldrdn: 0 newsuperior: cn=deleted users,cn=accounts,cn=provisioning,dc=idm,dc=example,dc=com
Before modifying a user, obtain the user’s distinguished name (DN) by searching using the user’s login. In the following example, the user_allowed_to_modify_user_entries user is a user allowed to modify user and group information, for example activator or IdM administrator. The password in the example is this user’s password:
# ldapsearch -LLL -x -D "uid=user_allowed_to_modify_user_entries,cn=users,cn=accounts,dc=idm,dc=example,dc=com" -w "Secret123" -H ldap://server.idm.example.com -b "cn=users,cn=accounts,dc=idm,dc=example,dc=com" uid=test_user
dn: uid=test_user,cn=users,cn=accounts,dc=idm,dc=example,dc=com
memberOf: cn=ipausers,cn=groups,cn=accounts,dc=idm,dc=example,dc=com
