community.general.keycloak_user_federation module – Allows administration of Keycloak user federations via Keycloak API

Note

This module is part of the community.general collection (version 4.8.3).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.general.

To use it in a playbook, specify: community.general.keycloak_user_federation.

New in version 3.7.0: of community.general

Synopsis

  • This module allows you to add, remove or modify Keycloak user federations via the Keycloak REST API. It requires access to the REST API via OpenID Connect; the user connecting and the client being used must have the requisite access rights. In a default Keycloak installation, admin-cli and an admin user would work, as would a separate client definition with the scope tailored to your needs and a user having the expected roles.

  • The names of module options are snake_cased versions of the camelCase ones found in the Keycloak API and its documentation at https://www.keycloak.org/docs-api/15.0/rest-api/index.html.

rdnLDAPAttribute

string

  • yes

usePasswordModifyExtendedOp

boolean

Use the LDAPv3 Password Modify Extended Operation (RFC-3062). The password modify extended operation usually requires that LDAP user already has password in the LDAP server. So when this is used with ‘Sync Registrations’, it can be good to add also ‘Hardcoded LDAP attribute mapper’ with randomly generated initial password.

Choices:

  • no ← (default)

  • yes

usernameLDAPAttribute

string

Name of LDAP attribute, which is mapped as Keycloak username. For many LDAP server vendors it can be uid. For Active directory it can be sAMAccountName or cn. The attribute should be filled for all LDAP user records you want to import from LDAP to Keycloak.

userObjectClasses

string

All values of LDAP objectClass attribute for users in LDAP divided by comma. For example inetOrgPerson, organizationalPerson. Newly created Keycloak users will be written to LDAP with all those object classes and existing LDAP user records are found just if they contain all those object classes.

usersDn

string

Full DN of LDAP tree where your users are. This DN is the parent of LDAP users.

useTruststoreSpi

string

Specifies whether LDAP connection will use the truststore SPI with the truststore configured in standalone.xml/domain.xml. Always means that it will always use it. Never means that it will not use it. Only for ldaps means that it will use if your connection URL use ldaps. Note even if standalone.xml/domain.xml is not configured, the default Java cacerts or certificate specified by javax.net.ssl.trustStore property will be used.

Choices:

  • always

  • ldapsOnly ← (default)

  • never

uuidLDAPAttribute

string

Name of LDAP attribute, which is used as unique object identifier (UUID) for objects in LDAP. For many LDAP server vendors, it is entryUUID; however some are different. For example for Active directory it should be objectGUID. If your LDAP server does not support the notion of UUID, you can use any other attribute that is supposed to be unique among LDAP users in tree.

boolean

Determines if Keycloak should validate the password with the realm password policy before updating it.

Choices:

  • no ← (default)

  • yes
