» 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.

» Create 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

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

  • 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.
  • clock_skew_leeway (int: <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. Only applicable with "jwt" roles.
  • expiration_leeway (int: <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. Only applicable with "jwt" roles.
  • not_before_leeway (int: <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. 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/values to match against. The expected value may be a single string or a list of strings.
  • 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.
  • claim_mappings (map: <optional>) - If set, a map of claims (keys) to be copied to specified metadata fields (values).
  • 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.
  • policies (array: []) - Policies to be set on tokens issued using this role.
  • ttl (string: "") - The TTL period of tokens issued using this role, provided as "1h", where hour is the largest suffix.
  • max_ttl (string: "") - The maximum allowed lifetime of tokens issued using this role.
  • period (string: "") - If set, indicates that the token generated using this role should never expire. The token should be renewed within the duration specified by this value. At each renewal, the token's TTL will be set to the value of this parameter.
  • bound_cidrs (string: "", or list: []) – If set, restricts usage of the roles to client IPs falling within the range of the specified CIDR(s).
