JWT/OIDC auth method (API)

This is the API documentation for the Vault JWT/OIDC auth method plugin. To learn more about the usage and operation, see the Vault JWT/OIDC method documentation.

This documentation assumes the plugin method is mounted at the /auth/jwt path in Vault. Since it is possible to enable auth methods at any location, please update your API calls accordingly.

Configure

Configures the validation information to be used globally across all roles. One (and only one) of oidc_discovery_url, jwks_url, and jwt_validation_pubkeys must be set.

Method	Path
POST	/auth/jwt/config

Parameters

• oidc_discovery_url (string: <optional>) - The OIDC Discovery URL, without any .well-known component (base path). Cannot be used with "jwks_url" or "jwt_validation_pubkeys".

• oidc_discovery_ca_pem (string: <optional>) - The contents of a CA certificate or chain of certificates, in PEM format, to use to validate connections to the OIDC Discovery URL. If not set, system certificates are used.

• oidc_client_id (string: <optional>) - The OAuth Client ID from the provider for OIDC roles.

• oidc_client_secret (string: <optional>) - The OAuth Client Secret from the provider for OIDC roles.

• oidc_response_mode (string: <optional>) - The response mode to be used in the OAuth2 request. Allowed values are "query" and "form_post". Defaults to "query". If using Vault namespaces, and oidc_response_mode is "form_post", then "namespace_in_state" should be set to false.

• oidc_response_types (comma-separated string, or array of strings: <optional>) - The response types to request. Allowed values are "code" and "id_token". Defaults to "code". Note: "id_token" may only be used if "oidc_response_mode" is set to "form_post".

• jwks_url (string: <optional>) - JWKS URL to use to authenticate signatures. Cannot be used with "oidc_discovery_url" or "jwt_validation_pubkeys".

• jwks_ca_pem (string: <optional>) - The contents of a CA certificate or chain of certificates, in PEM format, to use to validate connections to the JWKS URL. If not set, system certificates are used.

• jwt_validation_pubkeys (comma-separated string, or array of strings: <optional>) - A list of PEM-encoded public keys to use to authenticate signatures locally. Cannot be used with "jwks_url" or "oidc_discovery_url".

• bound_issuer (string: <optional>) - The value against which to match the iss claim in a JWT.

• jwt_supported_algs (comma-separated string, or array of strings: <optional>) - A list of supported signing algorithms. Defaults to [RS256] for OIDC roles. Defaults to all available algorithms for JWT roles.

• default_role (string: <optional>) - The default role to use if none is provided during login.

• provider_config (map: <optional>) - Configuration options for provider-specific handling. Providers with specific handling include: Azure, Google, SecureAuth, IBM ISAM. The options are described in each provider's section in OIDC Provider Setup.

• namespace_in_state (bool: true) - Pass namespace in the OIDC state parameter instead of as a separate query parameter. With this setting, the allowed redirect URL(s) in Vault and on the provider side should not contain a namespace query parameter. This means only one redirect URL entry needs to be maintained on the provider side for all vault namespaces that will be authenticating against it. Defaults to true for new configs.

Create/Update role

Registers a role in the method. Role types have specific entities that can perform login operations against this endpoint. Constraints specific to the role type must be set on the role. These are applied to the authenticated entities attempting to login. At least one of the bound values must be set.

Method	Path
POST	/auth/jwt/role/:name

Parameters

• name (string: <required>) - Name of the role.

• role_type (string: <optional>) - Type of role, either "oidc" (default) or "jwt".

• bound_audiences (array: <optional>) - List of aud claims to match against. Any match is sufficient. For "jwt" roles, at least one of bound_audiences, bound_subject, bound_claims or token_bound_cidrs is required. Optional for "oidc" roles.

• user_claim (string: <required>) - The claim to use to uniquely identify the user; this will be used as the name for the Identity entity alias created due to a successful login. The claim value must be a string.

• user_claim_json_pointer (bool: false) - Specifies if the user_claim value uses JSON pointer syntax for referencing claims. By default, the user_claim value will not use JSON pointer.

• clock_skew_leeway (int or string: <optional>) - The amount of leeway to add to all claims to account for clock skew, in seconds. Defaults to 60 seconds if set to 0 and can be disabled if set to -1. Accepts an integer number of seconds, or a Go duration format string. Only applicable with "jwt" roles.

• expiration_leeway (int or string: <optional>) - The amount of leeway to add to expiration (exp) claims to account for clock skew, in seconds. Defaults to 150 seconds if set to 0 and can be disabled if set to -1. Accepts an integer number of seconds, or a Go duration format string. Only applicable with "jwt" roles.

• not_before_leeway (int or string: <optional>) - The amount of leeway to add to not before (nbf) claims to account for clock skew, in seconds. Defaults to 150 seconds if set to 0 and can be disabled if set to -1. Accepts an integer number of seconds, or a Go duration format string. Only applicable with "jwt" roles.

• bound_subject (string: <optional>) - If set, requires that the sub claim matches this value.

• bound_claims (map: <optional>) - If set, a map of claims (keys) to match against respective claim values (values). The expected value may be a single string or a list of strings. The interpretation of the bound claim values is configured with bound_claims_type. Keys support JSON pointer syntax for referencing claims.

• bound_claims_type (string: "string") - Configures the interpretation of the bound_claims values. If "string" (the default), the values will treated as string literals and must match exactly. If set to "glob", the values will be interpreted as globs, with * matching any number of characters.

• groups_claim (string: <optional>) - The claim to use to uniquely identify the set of groups to which the user belongs; this will be used as the names for the Identity group aliases created due to a successful login. The claim value must be a list of strings. Supports JSON pointer syntax for referencing claims.

• claim_mappings (map: <optional>) - If set, a map of claims (keys) to be copied to specified metadata fields (values). Keys support JSON pointer syntax for referencing claims.

• oidc_scopes (list: <optional>) - If set, a list of OIDC scopes to be used with an OIDC role. The standard scope "openid" is automatically included and need not be specified.

• allowed_redirect_uris (list: <required>) - The list of allowed values for redirect_uri during OIDC logins.

• verbose_oidc_logging (bool: false) - Log received OIDC tokens and claims when debug-level logging is active. Not recommended in production since sensitive information may be present in OIDC responses.

• max_age (int or string: <optional>) - Specifies the allowable elapsed time in seconds since the last time the user was actively authenticated with the OIDC provider. If set, the max_age request parameter will be included in the authentication request. See AuthRequest for additional details. Accepts an integer number of seconds, or a Go duration format string.
