SAML v2

version

Available since version 1.6.0

SAML v2 identity providers connect to external SAML v2 login systems. This type of login will optionally provide a Login with ... button on FusionAuth's login page. This button is customizable by using different properties of the identity provider.

Optionally, this identity provider can define one or more domains it is associated with. This is useful for allowing employees to log in with their corporate credentials. As long as the company has an identity solution that provides SAML v2, you can leverage this feature. This is referred to as a Domain Based Identity Provider. If you enable domains for an identity provider, the Login with ... button will not be displayed. Instead, only the email form field will be displayed initially on the FusionAuth login page. Once the user types in their email address, FusionAuth will determine if the user is logging in locally or if they should be redirected to this identity provider. This is determined by extracting the domain from their email address and comparing it to the domains associated with the identity provider.

FusionAuth will locate the user's email address in the SAML assertion which will be used to create or lookup the existing user. Additional claims from the SAML response can be used to reconcile the User to FusionAuth by using a SAML v2 Reconcile Lambda. Unless you assign a reconcile lambda to this provider, on the email address will be used from the available assertions returned by the SAML v2 identity provider.

Integration Details#

The following values will likely be required by your SAML v2 Identity Provider in order to trust FusionAuth as a relying party.

These values are autogenerated and viewable within the UI after creating the Identity Provider. They can be viewed by navigating to Settings -> Identity Providers -> SAMLv2 -> View .

<base_url> is the URL for your FusionAuth instance, something like https://login.piedpiper.com.

<identityProviderId> is the Id of the Identity Provider, and will be a valid UUID.

<applicationId> is the id of the application that is the target of the login, and will be a valid UUID.

For an SP-initiated configuration:

Callback URL (ACS): <base_url>/samlv2/acs

For an IdP-initiated configuration (per application):

Callback URL (ACS): <base_url>/samlv2/acs/<identityProviderId>/<applicationId>

Issuer: <base_url>/samlv2/sp/<identityProviderId> by default.

To override this value, set identityProvider.issuer on the SAML v2 identity provider.

FusionAuth expects the Audience value in the SAML response assertion to match this same value.

Metadata URL: <base_url>/samlv2/sp/metadata/<identityProviderId>

Note: To receive a refresh token when completing the OAuth2 workflow when using an IdP initiated login, ensure you request the offline_access scope. To request a scope, add the following query parameter to your configured ACS in your IdP, ?scope=offline_access. When logging into the FusionAuth admin UI, this step is optional as the offline_access scope will be implicitly added.

Request#

Create a SAML v2 Identity Provider using a randomly generated Id

POST/api/identity-provider

OpenAPI Spec

Create a SAML v2 Identity Provider with the provided unique id

POST/api/identity-provider/{identityProviderId}

OpenAPI Spec

The type property in the request JSON indicates you are managing a SAML v2 identity provider.

Request Parameters#

identityProviderId UUID optional Defaults to secure random UUID Immutable

The Id to use for the new Identity Provider. If an id is not provided, a secure random UUID is generated.

Request Body#

identityProvider.applicationConfiguration Map<UUID, Object> optional

The configuration for each Application that the identity provider is enabled for.

identityProvider.applicationConfiguration[applicationId].buttonImageURL String optional

This is an optional Application specific override for the top level buttonImageURL.

identityProvider.applicationConfiguration[applicationId].buttonText String optional

This is an optional Application specific override for the top level buttonText.

identityProvider.applicationConfiguration[applicationId].createRegistration Boolean optional Defaults to true

Determines if a UserRegistration is created for the User automatically or not. If a user doesn't exist in FusionAuth and logs in through an identity provider, this boolean controls whether or not FusionAuth creates a registration for the User in the Application they are logging into.

identityProvider.applicationConfiguration[applicationId].enabled Boolean optional Defaults to false

Determines if this identity provider is enabled for the Application specified by the applicationId key.

identityProvider.assertionConfiguration.destination.alternates Array optional Available since 1.43.0

The array of URLs that FusionAuth will accept as SAML login destinations if the identityProvider.assertionConfiguration.destination.policy setting is AllowAlternates.

identityProvider.assertionConfiguration.destination.policy String optional Defaults to Enabled Available since 1.43.0

The policy to use when performing a destination assertion on the SAML login request.

The possible values are:

Enabled - Verifies the Destination attribute in the SAML response is equal to the expected Destination which is the FusionAuth ACS (Assertion Consumer Service) URL. This is the default and the recommended setting.
Disabled - Do not validate the Destination attribute. This is not recommended, please use with caution.
AllowAlternates - Verifies the Destination attribute is either the expected FusionAuth ACS, or one of the configured alternate values. This option is intended to assist with migrations from third-party IdPs and should be used with caution.

identityProvider.assertionDecryptionConfiguration.enabled Boolean optional Defaults to false Available since 1.55.1

Determines if FusionAuth requires encrypted assertions in SAML responses from the identity provider.

When true, SAML responses from the identity provider containing unencrypted assertions will be rejected by FusionAuth.

identityProvider.assertionDecryptionConfiguration.keyTransportDecryptionKeyId UUID optional Available since 1.55.1

The Id of the key stored in Key Master that is used to decrypt the symmetric key on the SAML response sent to FusionAuth from the identity provider. The selected Key must contain an RSA private key.

Required when identityProvider.assertionDecryptionConfiguration.enabled is true.

identityProvider.buttonImageURL String optional

The top-level button image (URL) to use on the FusionAuth login page for this Identity Provider.

identityProvider.buttonText String required

The top-level button text to use on the FusionAuth login page for this Identity Provider.

identityProvider.attributeMappings Map<String, String> optional Available since 1.65.0

A map of attribute mappings applied during user reconciliation when a reconcile Lambda is not configured.

Each key is the FusionAuth target field path and must begin with user. or registration.. Each value is the source expression in the identity provider response payload. A dot-notated value such as email or id_token.given_name is converted to a JSON Pointer. A value that starts with / is treated as a JSON Pointer as-is.

This property cannot be used with identityProvider.lambdaConfiguration.reconcileId.

This property is ignored when identityProvider.linkingStrategy is LinkAnonymously.

This property defaults to an empty map.

Mappings that resolve to null, cannot be extracted, or cannot be written to the target field are ignored. Mappings to user.password do not set a password.

identityProvider.debug Boolean optional Defaults to false Available since 1.7.3

Determines if debug is enabled for this provider. When enabled, an Event Log is created each time this provider is invoked to reconcile a login.

This is useful for debugging purposes, but is not intended to be left on during production. It should be enabled during integration or if you are experiencing an issue with this identity provider.

identityProvider.domains Array<String> optional

This is an optional list of domains that this SAML v2 provider should be used for. This converts the FusionAuth login form to a domain-based login form. This type of form first asks the user for their email. FusionAuth then uses their email to determine if an identity provider should be used. If an identity provider should be used, the browser is redirected to the login URL of that identity provider. Otherwise, the password field is revealed on the form so that the user can login using FusionAuth.

identityProvider.emailClaim String optional

The name of the email claim (attribute in the Assertion element) in the SAML response that FusionAuth uses to uniquely identity the user.

Required when identityProvider.useNameIdForEmail is false.

identityProvider.enabled Boolean optional Defaults to false

Determines if this provider is enabled. If it is false then it will be disabled globally.

identityProvider.idpEndpoint String required

The SAML v2 login page of the identity provider. Must be a valid URL.

identityProvider.idpInitiatedConfiguration.enabled Boolean optional Defaults to false Available since 1.43.0

Determines if FusionAuth will accept IdP initiated login requests from this SAMLv2 Identity Provider. A valid license is required to use this feature.

In general FusionAuth does not recommend you utilize this type of login due to the inherent risks of accepting an unsolicited authentication response from a third-party identity provider.

In a service provider initiated login, the SAML Authentication Response is returned to the service provider (FusionAuth) in response to an authentication request. This means FusionAuth can validate certain parameters and only accept a response for a request that FusionAuth initiated. In contrast, during an identity provider initiated login, the third-party identity provider sends FusionAuth a SAML Authentication Response indicating a user has been authenticated without any context. The problem is that FusionAuth did not initiate this so it is unexpected, and this limits what can be verified and requires FusionAuth to allow a cross site request from this third party.

If you must enable this feature to support a legacy integration or because the user experience is of the highest concern, then you may proceed.

identityProvider.idpInitiatedConfiguration.issuer String optional Available since 1.43.0

The EntityId (unique identifier) of the SAML v2 identity provider. This value should be provided to you.

Required when identityProvider.idpInitiatedConfiguration.enabled is true.

identityProvider.issuer String optional

The EntityId (unique identifier) FusionAuth uses as the SAML service provider.

When not provided, FusionAuth uses the default service provider EntityId of {'<base_url>/samlv2/sp/<identityProviderId>'}.

When provided, this value must not be an empty string.

identityProvider.keyId UUID required DEPRECATED

The Id of the key stored in Key Master that is used to verify the SAML response sent back to FusionAuth from the identity provider. This key must be a verification only key or certificate (meaning that it only has a public key component).

Deprecated since 1.69.0

In version 1.69.0 and above, use identityProvider.verificationKeyIds. For backward compatibility, Fusionauth populates identityProvider.defaultKeyId with the first entry in identityProvider.verificationKeyIds.

identityProvider.lambdaConfiguration.reconcileId UUID optional

The Id of a SAML reconcile lambda that is applied when the identity provider sends back a successful SAML response.

The specified Lambda Id must be of type SAMLv2Reconcile.

identityProvider.linkingStrategy String optional Defaults to LinkByEmail Available since 1.28.0

The linking strategy to use when creating the link between the SAML v2 Identity Provider and the user.

Available since 1.65.0 You can only change this value when the identity provider is disabled. To change the linking strategy for an identity provider that is already enabled, disable the provider, change the value, and then re-enable the provider.

The possible values are:

CreatePendingLink - Do not automatically link, instead return a pending link identifier that can be used to link to an existing user.
Disabled - Disables linking automatically. You must use the API to create links. Available since 1.37.0
LinkAnonymously - Always create a link based upon the unique Id returned by the identify provider. A username or email is not required and will not be used to link the user. A reconcile lambda will not be used in this configuration.
LinkByEmail - Link to an existing user based upon email. A user will be created with the email returned by the identity provider if one does not already exist.
LinkByEmailForExistingUser - Only link to an existing user based upon email. A user will not be created if one does not already exist with email returned by the identity provider.
LinkByUsername - Link to an existing user based upon username. A user will be created with the username returned by the identity provider if one does not already exist.
LinkByUsernameForExistingUser - Only link to an existing user based upon username. A user will not be created if one does not already exist with username returned by the identity provider.

identityProvider.loginHintConfiguration.enabled Boolean optional Defaults to true Available since 1.43.0

When enabled and HTTP-Redirect bindings are used, FusionAuth will provide the username or email address when available to the IdP as a login hint using the configured parameter name set by the identityProvider.loginHintConfiguration.parameterName to initiate the AuthN request.

identityProvider.loginHintConfiguration.parameterName String optional Defaults to login_hint Available since 1.43.0

The name of the parameter used to pass the username or email as login hint to the IDP when enabled, and HTTP redirect bindings are used to initiate the AuthN request.

Required when identityProvider.loginHintConfiguration.enabled is true.

identityProvider.name String required

The name of this SAML v2 identity provider. This is only used for display purposes. Must be unique across all identity providers.

identityProvider.nameIdFormat String required

The Name Id is used to facilitate communication about a user between a Service Provider (SP) and Identity Provider (IdP). The SP can specify the preferred format in the AuthN request regarding a user. The identity Provider will attempt to honor this format in the AuthN response. When this parameter is omitted a default value of urn:oasis:names:tc:SAML:2.0:nameid-format:persistent will be used.

identityProvider.postRequest Boolean optional Available since 1.20.0

When true the authentication request will use the HTTP POST binding with the identity provider instead of the default Redirect binding which uses the HTTP GET method.

identityProvider.requestSigningKeyId UUID optional Available since 1.20.0

The key pair Id to use to sign the SAML request.

Required when identityProvider.signRequest is true.

identityProvider.tenantConfiguration[tenantId].limitUserLinkCount.maximumLinks Integer Defaults to 42 Available since 1.32.0

The maximum number of links that a user can have for a particular identity provider. This configuration is specific to this IdP. So a user can have more links than this number, but for this particular IdP, the number of links will be limited and enforced.

identityProvider.tenantId UUID optional Available since 1.62.0

The unique Id of the Tenant.

Providing a value creates an identity provider scoped to the specified tenant, otherwise a global identity provider is created. Tenant-scoped identity providers can only be used to authenticate in the context of the specified tenant. Global identity providers can be used with any tenant.

This value is read-only once the identity provider is created.

identityProvider.type String required

This field must be set to SAMLv2.

identityProvider.uniqueIdClaim String optional

The name of the unique claim in the SAML response that FusionAuth uses to uniquely link the user. If this is not set, the emailClaim will be used when linking user.
