`saml:SP`

This authentication source is used to authenticate against SAML 2 IdPs.

Metadata

The metadata for your SP will be available from the federation page on your SimpleSAMLphp installation.

SimpleSAMLphp supports generating metadata with the MDUI and MDRPI metadata extensions and with entity attributes. See the documentation for those extensions for more details:

Parameters :

These are parameters that can be used at runtime to control the authentication. All these parameters override the equivalent option from the configuration.

saml:AuthnContextClassRef

The AuthnContextClassRef that will be sent in the login request.

saml:AuthnContextComparison

The Comparison attribute of the AuthnContext that will be sent in the login request. This parameter won't be used unless


   saml:AuthnContextClassRef

is set and contains one or more values. Possible values:

* `SAML2\Constants::COMPARISON_EXACT` (default)
* `SAML2\Constants::COMPARISON_BETTER`
* `SAML2\Constants::COMPARISON_MINIMUM`
* `SAML2\Constants::COMPARISON_MAXIMUM`

ForceAuthn

Force authentication allows you to force re-authentication of users even if the user has a SSO session at the IdP.

saml:idp

The entity ID of the IdP we should send an authentication request to.

isPassive

Send a passive authentication request.

IDPList

List of IdP entity ids that should be sent in the AuthnRequest to the IdP in the IDPList element, part of the Scoping element.

saml:Extensions

The samlp:Extensions (an XML chunk) that will be sent in the login request.

saml:logout:Extensions

The samlp:Extensions (an XML chunk) that will be sent in the logout request.

saml:NameID

Add a Subject element with a NameID to the SAML AuthnRequest for the IdP. This must be a \SAML2\XML\saml\NameID object.

saml:NameIDPolicy

The format of the NameID we request from the IdP: an array in the form of


   [ 'Format' => the format, 'AllowCreate' => true or false ]

. Set to an empty array

[]

to omit sending any specific NameIDPolicy element in the AuthnRequest.

saml:Audience

Add a Conditions element to the SAML AuthnRequest containing an AudienceRestriction with one or more audiences.

Authentication data

Some SAML-specific attributes are available to the application after authentication. To retrieve these attributes, the application can use the getAuthData() -function from the SP API . The following attributes are available:

saml:sp:IdP: The entityID of the IdP the user is authenticated against.
saml:sp:NameID: The NameID the user was issued by the IdP. This is a \SAML2\XML\saml\NameID object with the various fields from the NameID.
saml:sp:SessionIndex: The SessionIndex we received from the IdP.

Options :

acs.Bindings

List of bindings the SP should support. If it is unset, all will be added.

Possible values:

* `urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST`
* `urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Artifact`
* `urn:oasis:names:tc:SAML:2.0:profiles:holder-of-key:SSO:browser`

assertion.encryption

Whether assertions received by this SP must be encrypted. The default value is


   false

. If this option is set to


   true

, unencrypted assertions will be rejected.

Note that this option can be overridden for a specific IdP in saml20-idp-remote.

AssertionConsumerService

List of Assertion Consumer Services in the generated metadata. Specified in the format detailed in the Metadata endpoints documentation. Note that this list is taken at face value, so it's not useful to list anything here that the SP auth source does not actually support (unless the URLs point externally).

AssertionConsumerServiceIndex

The Assertion Consumer Service Index to be used in the AuthnRequest in place of the Assertion Service Consumer URL.

attributes

List of attributes this SP requests from the IdP. This list will be added to the generated metadata.

The attributes will be added without a


   NameFormat

by default. Use the


   attributes.NameFormat

option to specify the


   NameFormat

for the attributes.

An associative array can be used, mixing both elements with and without keys. When a key is specified for an element of the array, it will be used as the friendly name of the attribute in the generated metadata.

Note : This list will only be added to the metadata if the


   name

-option is also specified.

attributes.NameFormat

The


   NameFormat

for the requested attributes.

attributes.index

The


   index

attribute that is set in the md:AttributeConsumingService element. Integer value that defaults to

attributes.isDefault

If present, sets the


   isDefault

attribute in the md:AttributeConsumingService element. Boolean value, when unset, the attribute will be omitted.

attributes.required

If you have attributes added you can here specify which should be marked as required.

The attributes should still be present in


   attributes

AuthnContextClassRef

The SP can request authentication with one or more specific authentication context classses. One example of usage could be if the IdP supports both username/password authentication as well as software-PKI. Set this to a string for one class identifier or an array of requested class identifiers.

AuthnContextComparison

The Comparison attribute of the AuthnContext that will be sent in the login request. This parameter won't be used unless


   saml:AuthnContextClassRef

is set and contains one or more values. Possible values:

* `SAML2\Constants::COMPARISON_EXACT` (default)
* `SAML2\Constants::COMPARISON_BETTER`
* `SAML2\Constants::COMPARISON_MINIMUM`
* `SAML2\Constants::COMPARISON_MAXIMUM`

authproc

Processing filters that should be run after SP authentication. See the authentication processing filter manual .

certData

Base64 encoded certificate data. Can be used instead of the


   certificate

option.

certificate

File name of certificate for this SP. This certificate will be included in generated metadata.

contacts

Specify contacts in addition to the


   technical

contact configured through


   config/config.php

For example, specifying a support contact:

    'contacts' => [
        [
            'contactType'       => 'support',
            'emailAddress'      => 'support@example.org',
            'givenName'         => 'John',
            'surName'           => 'Doe',
            'telephoneNumber'   => '+31(0)12345678',
            'company'           => 'Example Inc.',
        ],
    ],

Valid values for contactType are: technical , support , administrative , billing and other . All fields, except contactType are OPTIONAL.

description

A description of this SP. Will be added to the generated metadata, in an AttributeConsumingService element.

This option can be translated into multiple languages by specifying the value as an array of language-code to translated description:

    'description' => [
        'en' => 'A service',
        'no' => 'En tjeneste',
    ],

Note : For this to be added to the metadata, you must also specify the attributes and name options.

disable_scoping

Whether sending of samlp:Scoping elements in authentication requests should be suppressed. The default value is


   false

. When set to


   true

, no scoping elements will be sent. This does not comply with the SAML2 specification, but allows interoperability with ADFS which does not support Scoping elements .

Note that this option also exists in the IdP remote configuration. An entry in the IdP-remote metadata overrides this the option in the SP configuration.

enable_unsolicited

Whether this SP is willing to process unsolicited responses. The default value is


   true

discoURL

Set which IdP discovery service this SP should use. If this is unset, the IdP discovery service specified in the global option


   idpdisco.url.saml20


   config/config.php

will be used. If that one is also unset, the builtin default discovery service will be used.

encryption.blacklisted-algorithms

Blacklisted encryption algorithms. This is an array containing the algorithm identifiers.

Note that this option can be set for each IdP in the IdP-remote metadata .

entityID

The entity ID this SP should use. (Must be set or an error will be generated.)

The entity ID must be a URI, that is unlikely to change for technical or political reasons. We recommend it to be a domain name, like above, if your organization's main domain is


   example.org

and this SP is for the application


   myapp

. The URL does not have to resolve to actual content, it's just an identifier. Hence you don't need to and should not change it if the actual domain of your application changes.

For guidance in picking an entityID, see InCommon's best practice on the matter.

ForceAuthn

Force authentication allows you to force re-authentication of users even if the user has a SSO session at the IdP.

idp

The entity ID this SP should connect to.

If this option is unset, an IdP discovery service page will be shown.

IsPassive

IsPassive allows you to enable passive authentication by default for this SP.

key_name

The name of the certificate. It is possible the IDP requires your certificate to have a name. If provided, it will be exposed in the SAML 2.0 metadata as


   KeyName

inside the


   KeyDescriptor

. This also requires a certificate to be provided.

name

The name of this SP. Will be added to the generated metadata, in an AttributeConsumingService element.

This option can be translated into multiple languages by specifying the value as an array of language-code to translated name:

    'name' => [
        'en' => 'A service',
        'no' => 'En tjeneste',
    ],,

Note : You must also specify at least one attribute in the attributes option for this element to be added to the metadata.

nameid.encryption

Whether NameIDs sent from this SP should be encrypted. The default value is


   false

Note that this option can be set for each IdP in the IdP-remote metadata .

NameIDFormat

An array of the format(s) listed in the SP metadata that this SP will accept. Example:

    'NameIDFormat' => [
        \SAML2\Constants::NAMEID_PERSISTENT,
        \SAML2\Constants::NAMEID_TRANSIENT,
    ],

NameIDPolicy

The format of the NameID we request from the IdP in the AuthnRequest: an array in the form of


   [ 'Format' => the format, 'AllowCreate' => true or false ]

. Set to an empty array

[]

to omit sending any specific NameIDPolicy element in the AuthnRequest. When the entire option or either array key is unset, the defaults are transient and true respectively.

OrganizationName , OrganizationDisplayName , OrganizationURL

The name and URL of the organization responsible for this IdP. You need to either specify all three or none of these options.

The Name does not need to be suitable for display to end users, the DisplayName should be. The URL is a website the user can access for more information about the organization.

This option can be translated into multiple languages by specifying the value as an array of language-code to translated name:

    'OrganizationName' => [
        'en' => 'Voorbeeld Organisatie Foundation b.a.',
        'nl' => 'Stichting Voorbeeld Organisatie b.a.',
    ],
    'OrganizationDisplayName' => [
        'en' => 'Example organization',
        'nl' => 'Voorbeeldorganisatie',
    ],
    'OrganizationURL' => [
        'en' => 'https://example.com',
        'nl' => 'https://example.com/nl',
    ],

privatekey

File name of private key to be used for signing messages and decrypting messages from the IdP. This option is only required if you use encrypted assertions or if you enable signing of messages.

privatekey_pass

The passphrase for the private key, if it is encrypted. If the private key is unencrypted, this can be left out.

ProviderName

Human readable name of the local SP sent with the authentication request.

ProtocolBinding

The binding that should be used for SAML2 authentication responses. This option controls the binding that is requested through the AuthnRequest message to the IdP. By default the HTTP-Post binding is used.

redirect.sign

Whether authentication requests, logout requests and logout responses sent from this SP should be signed. The default is


   false

. If set, the


   AuthnRequestsSigned

attribute of the


   SPSSODescriptor

element in SAML 2.0 metadata will contain its value. This option takes precedence over the


   sign.authnrequest

option in any metadata generated for this SP.

redirect.validate

Whether logout requests and logout responses received by this SP should be validated. The default is


   false

RegistrationInfo

Allows to specify information about the registrar of this SP. Please refer to the MDRPI extension document for further information.

RelayState

The page the user should be redirected to after an IdP initiated SSO.

RequestInitiation

Enable the Service Provider Request Initiation Protocol . To validate the


   target

the


   trusted.url.domains

configuration option has to be used.

saml.SOAPClient.certificate

A file with a certificate and private key that should be used when issuing SOAP requests from this SP. If this option isn't specified, the SP private key and certificate will be used.

This option can also be set to


   false

, in which case no client certificate will be used.

saml.SOAPClient.privatekey_pass

The passphrase of the privatekey in


   saml.SOAPClient.certificate

saml20.hok.assertion

Enable support for the SAML 2.0 Holder-of-Key SSO profile. See the documentation for the Holder-of-Key profile .

sign.authnrequest

Whether to sign authentication requests sent from this SP. If set, the


   AuthnRequestsSigned

attribute of the


   SPSSODescriptor

element in SAML 2.0 metadata will contain its value.

Note that this option also exists in the IdP-remote metadata, and any value in the IdP-remote metadata overrides the one configured in the SP configuration.

sign.logout

Whether to sign logout messages sent from this SP.

Note that this option also exists in the IdP-remote metadata, and any value in the IdP-remote metadata overrides the one configured in the SP configuration.

signature.algorithm

The algorithm to use when signing any message generated by this service provider. Defaults to RSA-SHA256.

Possible values:

* `http://www.w3.org/2000/09/xmldsig#rsa-sha1`
   *Note*: the use of SHA1 is **deprecated** and will be disallowed in the future.
* `http://www.w3.org/2001/04/xmldsig-more#rsa-sha256`
  The default.
* `http://www.w3.org/2001/04/xmldsig-more#rsa-sha384`
* `http://www.w3.org/2001/04/xmldsig-more#rsa-sha512`

* `urn:oasis:names:tc:SAML:2.0:bindings:SOAP`

SingleLogoutServiceLocation

The Single Logout Service URL published in the generated metadata.

validate.logout

Whether we require signatures on logout messages sent to this SP.

Note that this option also exists in the IdP-remote metadata, and any value in the IdP-remote metadata overrides the one configured in the IdP metadata.

WantAssertionsSigned

Whether assertions received by this SP must be signed. The default value is


   false

. The value set for this option will be used to set the


   WantAssertionsSigned

attribute of the


   SPSSODescriptor

element in the exported SAML 2.0 metadata.
