|The SAML Entity ID that the remote Identity Provider uses to identify requests from this Service Provider. By default, this setting is set to the realms base URL `<root>{kc_realms_path}/{realm-name}`.
|The SAML Entity ID used to validate the Issuer element in received SAML assertions. If empty, no Issuer validation is performed. If your SAML IDP publishes an IDP entity descriptor, the value of this field is specified there.
|The SAML endpoint that starts the authentication process. If your SAML IDP publishes an IDP entity descriptor, the value of this field is specified there.
|The URI reference corresponding to a name identifier format. By default, {project_name} sets it to `urn:oasis:names:tc:SAML:2.0:nameid-format:persistent`.
|Specifies which part of the SAML assertion will be used to identify and track external user identities. Can be either Subject NameID or SAML attribute (either by name or by friendly name). Subject NameID value can not be set together with 'urn:oasis:names:tc:SAML:2.0:nameid-format:transient' NameID Policy Format value.
|If a Principal type is non-blank, this field specifies the name ("Attribute [Name]") or the friendly name ("Attribute [Friendly Name]") of the identifying attribute.
|Signed SAML documents sent using POST binding contain the identification of signing key in `KeyName` element, which, by default, contains the {project_name} key ID. External SAML IDPs can expect a different key name. This switch controls whether `KeyName` contains:
* `KEY_ID` - Key ID.
* `CERT_SUBJECT` - the subject from the certificate corresponding to the realm key. Microsoft Active Directory Federation Services expect `CERT_SUBJECT`.
* `NONE` - {project_name} omits the key name hint from the SAML message.
|Controls if {project_name} forwards a `login_hint` query parameter to the IDP. {project_name} adds this field's value to the login_hint parameter in the AuthnRequest's Subject so destination providers can pre-fill their login form.
|Identifies the attribute set to request to the remote IDP. {project_name} automatically adds the attributes mapped in the identity provider configuration to the autogenerated SP metadata document.
|Attribute Consuming Service Name
|A descriptive name for the set of attributes that are advertised in the autogenerated SP metadata document.
You can import all configuration data by providing a URL or a file pointing to the SAML IDP entity descriptor of the external IDP. If you are connecting to a {project_name} external IDP, you can import the IDP settings from the URL `<root>{kc_realms_path}/{realm-name}/protocol/saml/descriptor`. This link is an XML document describing metadata about the IDP. You can also import all this configuration data by providing a URL or XML file pointing to the external SAML IDP's entity descriptor to connect to.
Identity Providers facilitate clients specifying constraints on the authentication method verifying the user identity. For example, asking for MFA, Kerberos authentication, or security requirements. These constraints use particular AuthnContext criteria. A client can ask for one or more criteria and specify how the Identity Provider must match the requested AuthnContext, exactly, or by satisfying other equivalents.
You can list the criteria your Service Provider requires by adding ClassRefs or DeclRefs in the Requested AuthnContext Constraints section. Usually, you need to provide either ClassRefs or DeclRefs, so check with your Identity Provider documentation which values are supported. If no ClassRefs or DeclRefs are present, the Identity Provider does not enforce additional constraints.
|The method the Identity Provider uses to evaluate the context requirements. The available values are `Exact`, `Minimum`, `Maximum`, or `Better`. The default value is `Exact`.
When you access the provider's SAML SP metadata, look for the `Endpoints` item in the identity provider configuration settings. It contains a `SAML 2.0 Service Provider Metadata` link which generates the SAML entity descriptor for the Service Provider. You can download the descriptor or copy its URL and then import it into the remote Identity Provider.
Adding a query parameter named `login_hint` to this URL adds the parameter's value to SAML request as a Subject attribute. If this query parameter is empty, {project_name} does not add a subject to the request.
