You can have Infisical automatically sync group memberships between your OIDC provider and Infisical by configuring a groups claim on your provider tokens. When a user logs in via OIDC, they will be added to Infisical groups that are present in their OIDC groups claim, and removed from any Infisical groups not present in the claim.
When enabled, manual management of Infisical group memberships will be disabled.
Group membership changes in your OIDC provider only sync with Infisical when a user logs in via OIDC. For example, if you remove a user from a group in your OIDC provider, 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.
