Keycloak OIDC Group Membership Mapping
Learn how to sync Keycloak group members to matching groups in Infisical.
You can have Infisical automatically sync group memberships between Keycloak and Infisical by configuring a group membership mapper in Keycloak. When a user logs in via OIDC, they will be added to Infisical groups that match their Keycloak groups names, and removed from any Infisical groups not present in their groups claim.
When enabled, manual management of Infisical group memberships will be disabled.
Group membership changes in the Keycloak only sync with Infisical when a user logs in via OIDC. For example, if you remove a user from a group in Keycloak, this change will not be reflected in Infisical until their next OIDC login. To ensure this behavior, Infisical recommends enabling Enforce OIDC SSO in the OIDC settings.
