Auth methods

An auth method is a resource that provides a mechanism for users to authenticate to Boundary. An auth method contains accounts which link an individual user to a set of credentials and managed groups which groups accounts that satisfy criteria and can be used as principals in roles. Auth methods can be defined at either a Global or Organization scope.

Attributes

All auth methods have the following configurable attributes:

  • name - (optional) If set, the name must be unique within the auth method's scope.

  • description - (optional)

Password auth method attributes

The password auth method has the following additional attributes:

OIDC auth method attributes

The OIDC auth method has the following additional attributes:

  • account_claim_maps (optional list) These are a map from custom claims to the standard claims of sub, name, and email. These maps are represented as key=value where the key equals the provider from-claim and the value equals the Boundary to-claim. For example "oid=sub". You can specify this attribute multiple times for different to-claims.

  • allowed_audiences (optional list) Audiences for which provider responses are allowed.

  • api_url_prefix (required) The API prefix to use when generating callback URLs for the provider. You should set the value to an address that allows the provider to reach the controller.

  • callback_url (output read-only) The URL that should be provided to the IdP for callbacks.

  • claims_scopes (optional list) The claims scope requested. You can specify this attribute multiple times.

  • client_id (required) The OAuth 2.0 client identifier this auth method should use with the provider.

  • client-secret (required) The corresponding client secret.

  • client_secret_hmac (output read-only) The HMAC of the client secret that the Boundary controller returns. It is used for comparison to the value's initial setting.

  • disable_discovered_config_validation (optional) Disables validation logic to ensure that the OIDC provider's information from its discovery endpoint matches the information here. The validation is only performed at create or update time.

  • idp_ca_certs - (optional) PEM-encoded X.509 CA certificate that can be used as trust anchors when you connect to an OIDC provider. You can specify this attribute multiple times.

  • issuer - (required) The provider's issuer URL. This value must match the issuer field in generated tokens.

  • max_age (optional) The max age to send to the provider. This value indicates how much time is allowed to have passed since the last authentication before the user is challenged again. A value of 0 sets an immediate requirement for all users to reauthenticate, and an unset maxAge results in a Terraform value of -1 and the default TTL of the chosen OIDC is used.

    If you set a max_age value, it works in conjunction with the auth_token_time_to_live parameter set on the controller. Users are not challenged to authenticate again by the provider until the auth_token_time_to_live value has expired, even if the max_age expires first.

  • prompt (optional) If you configure this attribute, the OIDC authorization server prompts users for reauthentication, account selection, or consent when they log in. You can optionally configure one or more of the following additional attributes to customize the behavior of the authentication process:

    • none (optional) The authorization server does not display any authentication or consent prompts.
    • login (optional) The authorization server prompts users for reauthentication before allowing them to log in.
    • consent (optional) The authorization server prompts users for consent before returning any information to Boundary.
    • select_account (optional) The authorization server prompts users to select a user account. The select_account setting can be helpful if your users have multiple accounts.

Note

Cloud providers implement prompt in different ways. You may notice differences in behavior if you configure OIDC authentication on multiple cloud providers.

  • signing-algorithm (required) The allowed signing algorithm. You can specify this attribute multiple times for multiple values.

LDAP auth method attributes

The ldap auth method has the following additional attributes:

  • state - The state of the auth method; either inactive, active-private, or active-public.

  • start_tls - (optional) If true, issues a StartTLS command after establishing an unencrypted connection. Defaults to false.

  • insecure_tls - (optional) If true, skips LDAP server SSL certificate validation, which is insecure and should be used with caution. Defaults to false.

  • discover_dn - (optional) If true, use anon bind to discover the bind DN (Distinguished Name) of a user. Defaults to false.

  • anon_group_search - (optional) If true, use anon bind when performing LDAP group searches. Defaults to false.

  • upn_domain - (optional) If set, the userPrincipalDomain is used to construct the UPN string for the authenticating user. The constructed UPN appears as [username]@UPNDomain. Example: example.com, which causes Boundary to bind as username@example.com when it authenticates the user.

  • urls - (required) The LDAP URLS that specify LDAP servers to connect to. There must be at least one URL for each LDAP auth method. When attempting to connect, the URLs are tried in the order specified.

  • user_dn - (optional) If set, the base DN under which to perform user search. Example: ou=Users,dc=example,dc=com.

  • user_attr - (optional) If set, defines the attribute on a user's entry matching the login-name passed when the user authenticates. Examples: cn, uid

  • user_filter - (optional) If set, the Go template used to construct an LDAP user search filter. The template can access the following context variables: [UserAttr, Username]. The default user_filter is ({{.UserAttr}}={{.Username}}) or (userPrincipalName={{.Username}}@UPNDomain) if the upn-domain parameter is set.

  • enable_groups - (optional) If true, an authenticated user's groups are found during authentication. Defaults to false.

  • group_dn - (optional) If set, the base DN under which to perform a group search. Example: ou=Groups,dc=example,dc=com.

    Note: There is no default, so no base DN is used for group searches, if it's not specified.

  • group_attr - (optional) If set, the LDAP attribute to follow on objects returned by group_filter in order to enumerate user group membership. Examples: for group_filter queries returning group objects, use: cn. For queries returning user objects, use: memberOf. The default is cn.

  • group_filter - (optional) If set, the Go template used when constructing the group membership query. The template can access the following context variables: UserDN, Username. The default is (|(memberUid={{.Username}})(member={{.UserDN}})(uniqueMember={{.UserDN}})), which is compatible with several common directory schemas.

  • certificates - (optional) If set, PEM encoded x509 certificates in ASN.1 DER form that can be used as trust anchors when connecting to an LDAP provider.

  • client_certificate - (optional) If set, a PEM encoded x509 certificate in ASN.1 DER form to be used as a client certificate. It must be set, if you specify the optional client_certificate_key.

  • client_certificate_key - (optional) If set, a PEM encoded certificate key in PKCS #8, ASN.1 DER form. It must be set, if you specify the optional client_certificate.

  • bind_dn - (optional) If set, the distinguished name of entry to bind when performing user and group searches. Example: cn=vault,ou=Users,dc=example,dc=com.

  • bind_password - (optional) If set, the password to use along with bind_dn when performing user search. It must be set, if you specify the optional bind_dn.

  • use_token_groups - (optional) If true, use the Active Directory tokenGroups constructed attribute of the user to find the group memberships. This finds all security groups, including nested ones.

  • account_attribute_maps - (optional) If set, the attribute maps from custom attributes to the standard fullname and email account attributes. These maps are represented as key=value where the key equals the from_attribute, and the value equals the to_attribute. For example, preferredName=fullName. All attribute names are case insensitive.

    • maximum_page_size - (optional) If set, it specifies a maximum ldap search result size to use when retrieving the authenticated user's group memberships. You can use this setting to avoid reaching the LDAP server's max result size.

    • dereference_aliases - (optional) If set, it will control how aliases are dereferenced when you search.
