ACL Auth Methods HTTP API

The /acl/auth-methods and /acl/auth-method endpoints are used to manage ACL Auth Methods.

Create Auth Method

This endpoint creates an ACL Auth Method. The request is always forwarded to the authoritative region.

Method	Path	Produces
`POST`	`/acl/auth-method`	`application/json`

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking Queries	ACL Required
`NO`	`management`

Parameters

Name (string: <required>) - Names is the identifier of the ACL Auth Method. The name can contain alphanumeric characters, dashes, and underscores. This name must be unique and must not exceed 128 characters.
Type (string: <required>) - ACL Auth Role SSO identifier.
TokenLocality (string: <required>) - Defines whether the ACL Auth Method creates a local or global token when performing SSO login. This field must be set to either "local" or "global"
TokenNameFormat (string <optional>) - Defines the token name format for the generated tokens This can be lightly templated using HIL '${foo}' syntax. Defaults to '${auth_method_type}-${auth_method_name}'
MaxTokenTTL (duration: <required>) - Defines the maximum life of a token created by this method. When set, it will initialize the ExpirationTime field on all tokens to a value of Token.CreateTime + AuthMethod.MaxTokenTTL. This field is not persisted beyond its initial use. Can be specified in the form of "60s" or "5m" (i.e., 60 seconds or 5 minutes, respectively).
Default (bool: false) - Defines whether this ACL Auth Method is to be set as default when running nomad login command.
Config (ACLAuthMethodConfig: <required>) - The raw configuration to use for the auth method. This parameter is part of the auth method configuration, not specific to Nomad.
- OIDCDiscoveryURL (string: <required>) - The OIDC Discovery URL, without any .well-known component (base path).
- OIDCClientID (string: <required>) - The OAuth Client ID configured with your OIDC provider.
- OIDCClientSecret (string: <required>) - The OAuth Client Secret configured with your OIDC provider.
- OIDCScopes (array<string>) - List of OIDC scopes.
- BoundAudiences (array<string>) - List of aud claims that are valid for login; any match is sufficient.
- AllowedRedirectURIs (array<string>) - A list of allowed values for redirect_uri. Must be non-empty.
- DiscoveryCaPem (array<string>) - PEM encoded CA certs for use by the TLS client used to talk with the OIDC Discovery URL. If not set, system certificates are used.
- SigningAlgs (array<string>) - A list of supported signing algorithms. Defaults to RS256.
- ClaimMappings (map[string]string) - Mappings of claims (key) that will be copied to a metadata field (value). Use this if the claim you are capturing is singular (such as an attribute).
  When mapped, the values in each list can be any of a number, string, or boolean and will all be stringified when returned.
- ListClaimMappings (map[string]string) - Mappings of claims (key) will be copied to a metadata field (value). Use this if the claim you are capturing is list-like (such as groups).
