FieldDescriptionSample value
IssuerSpecify the Issuer. This is the <saml:Issuer> element that contains the unique identifier of the service provider. This is also the issuer value specified in the SAML Authentication Request issued by the service provider. When configuring single-sign-on across Carbon servers, ensure that this value is equal to the ServiceProviderID value mentioned in the <IS_HOME>/repository/conf/security/authenticators.xml file of the relying party Carbon server.travelocity.com
Assertion Consumer URLsSpecify the Assertion Consumer URLs. This is the URL to which the browser should be redirected to after the authentication is successful. This is the Assertion Consumer Service (ACS) URL of the service provider. The identity provider redirects the SAML2 response to this ACS URL. However, if the SAML2 request is signed and SAML2 request contains the ACS URL, the Identity Server will honor the ACS URL of the SAML2 request. It should have this format: https://(host-name):(port)/acs. You can add multiple assertion consumer URLs for the service provider by entering the URL and clicking the Add button.http://wso2is.local:8080/travelocity.com/home.jsp
Default Assertion Consumer URL

Since there can be multiple assertion consumer URLs, you must define a Default Assertion Consumer URL in case you are unable to retrieve it from the authentication request.

Tip

Tip: In a service provider initiated single sign-on setup, the following needs to be considered.

  • If no ACS URL is given in the <AuthnRequest>, the Identity Server sends the response to the default ACS URL of the service provider (whether the request is signed or not).
  • If the ACS URL in <AuthnRequest> matches with one of the registered URLs, the Identity Server sends the response to the matched one. 
  • If the ACS URL in <AuthnRequest> does not match any of the registered ACS URLs and if the request is signed, the Identity Server sends the response to the ACS URL in the request only if the signature is valid. Alternatively, the <AuthnRequest> is rejected.

In an identity provider initiated single sign-on setup, the following needs to be considered.

  • If the “acs” query parameter is not present in the request, the Identity Server sends the response to default ACS URL of the service provider.
  • If the "acs” parameter is present and the value of that parameter matches with any of the registered ACS URLs of the service provider, then the Identity Server sends the response to the matched one.

NameID format

Specify the NameID format. This defines the name identifier formats supported by the identity provider. The service provider and identity provider usually communicate with each other regarding a specific subject. That subject should be identified through a Name-Identifier (NameID) , which should be in some format so that It is easy for the other party to identify it based on the format. Name identifiers are used to provide information regarding a user. 

Info
titleAbout NameID formats

For SSO interactions, you can use the following types of NameID formats.

This specifies the name identifier format that the Identity Server wants to receive in the subject of an assertion from a particular identity provider. The following is the default format used by the identity provider.

urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress

Certificate Alias

Select the Certificate Alias from the dropdown. This is used to validate the signature of SAML2 requests and is used to generate encryption. Basically the service provider’s certificate must be selected here. Note that this can also be the Identity Server tenant's public certificate in a scenario where you are doing a tenant specific configuration.

Response Signing Algorithm

Specifies the ‘SignatureMethod’ algorithm to be used in the ‘Signature’ element in POST binding. The default value can be configured in the <IS_HOME>/repository/conf/identity.xml file, in the SSOService element with SAMLDefaultSigningAlgorithmURI tag. If it is not provided the default algorithm is RSA­SHA 1, at URI ‘http://www.w3.org/2000/09/xmldsig#rsa­sha1’'.

http://www.w3.org/2000/09/xmldsig#rsa­sha1
Response Digest Algorithm

Specifies the ‘DigestMethod’ algorithm to be used in the ‘Signature’ element in POST binding. The default value can be configured in the <IS_HOME>/repository/conf/identity.xml file, in the SSOService element with SAMLDefaultDigestAlgorithmURI tag. If it is not provided the default algorithm is SHA 1, at URI ‘ http://www.w3.org/2000/09/xmldsig#sha1 ’.

 http://www.w3.org/2000/09/xmldsig#sha1
Assertion Encryption AlgorithmThe algorithm that the SAML2 assertion is encrypted. The default value can be configured in the <IS_HOME>/repository/conf/identity.xml file, in the SSOService element with SAMLDefaultAssertionEncryptionAlgorithm URI tag. The default is http://www.w3.org/2001/04/xmlenc#aes256-cbc.www.w3.org/2001/04/xmlenc#aes256-cbc
Key Encryption AlgorithmThe algorithm that the SAML2 key is encrypted. The default value can be configured in the <IS_HOME>/repository/conf/identity.xml file, in the SSOService element with SAMLDefaultKeyEncryptionAlgorithm URI tag. The default algorithm is http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p
Enable Response SigningSelect Enable Response Signing to sign the SAML2 Responses returned after the authentication process.Selected
Enable Signature Validation in Authentication Requests and Logout Requests Select Enable Signature Validation in Authentication Requests and Logout Requests if you need this functionality configured. This specifies whether the identity provider must validate the signature of the SAML2 authentication request and the SAML2 logout request that are sent by the service provider. Unselected
Enable Assertion EncryptionEnable Assertion Encryption, if you wish to encrypt the assertion.Unselected
Enable Single LogoutSelect Enable Single Logout so that all sessions are terminated once the user signs out from one server. If single logout is enabled, the identity provider sends logout requests to all service providers. Basically, the identity provider acts according to the single logout profile. If the service provider supports a different URL for logout, you can enter a SLO Response URL and SLO Request URL for logging out. These URLs indicate where the request and response should go to. If you do not specify this URL, the identity provider uses the Assertion Consumer Service (ACS) URL. Selected
Enable Attribute Profile Select Enable Attribute Profile to enable this and add a claim by entering the claim link and clicking the Add Claim button. The Identity Server provides support for a basic attribute profile where the identity provider can include the user’s attributes in the SAML Assertions as part of the attribute statement. Once you select the checkbox to Include Attributes in the Response Always, the identity provider always includes the attribute values related to the selected claims in the SAML attribute statement.Unselected
Enable Audience RestrictionSelect Enable Audience Restriction to restrict the audience. You may add audience members using the Audience text box and clicking the Add button.Unselected
Enable Recipient Validation Select this if you require validation from the recipient of the response.Unselected
Enable IdP Initiated SSOSelect the Enable IdP Initiated SSO checkbox to enable this functionality. When this is enabled, the service provider is not required to send the SAML2 request. Unselected
Enable IdP Initiated SLOSelect the Enable IdP Initiated SLO checkbox to enable this functionality. You must specify the URL.Unselected
Enable Assertion Query Request ProfileSelect the Enable Assertion Query Request Profile checkbox to query assertions that are persisted to the database when you login to the service provider application. For more information, see Querying SAML Assertions.Unselected

...

Metadata for a service provider may be published in a well known location via a URI. This option allows you to provide the configuration data required for configuring SAML2, by providing a URI instead (Ex: "https://spconfigs.com/sample-sp.xml") instead of having to manually enter the values. This enables faster entry of configuration data and allows the user to use the same metadata XML file for multiple instances of entity configuration.

  • If you need to sign the SAML response using an authenticated user's tenant keystore, please add the following configuration. (By default, the response is signed using the certificate that belongs to the tenant where the service provider is registered). This property must be added if the SAML authenticator version in the WSO2 Carbon products that you are using is 4.2.2 or higher (org.wso2.carbon.identity.authenticator.saml2.sso_4.2.2.jar).

    Add the <UseAuthenticatedUserDomainCrypto> property available in the <IS_HOME>/repository/conf/identity.xml file as shown below.
