Logging in to Workday using the Identity Server

Configuring Workday

1. Login to the Workday account as an administrator.
2. Open the Edit Tenant Setup and click Security. 
3. Select the Enable SAML Authentication checkbox.
   
4. Enter the identity provider name and the issuer as follows.
   
   • Identity Provider Name: wso2_is
   • Issuer: localhost

   Note: The issuer name must be equal to the issuer value that comes with the SAML Response from the identity provider.

   

5. Add the public certificate of the Identity Provider (which you extracted as a prerequisite)  
6. Click on create and insert Name, Valid To, Valid from, and the certificate in the interface that appears.  
   

   You can get the certificate's info and validate it here.

7. Enable the Workday initiated logout as seen below. 
8. Set the following environments.
   
9. Generate a private key pair if you do not already have one. This certificate will be used inside the WSO2 IS to validate the incoming authentication and logout requests from Workday.

   

   Tip: You can import a certificate to the WSO2 trust store using the following command (pw: wso2carbon).

   keytool -import -alias workday -file workday.crt -keystore client-truststore.jks

   Restart WSO2 Identity Server after the certificate import.

10. Enter the following details and click OK. Finally, click Done.

    Field	Sample Value
    Service Provider ID The Service provider ID must start with "http://www.workday.com/".	http://www.workday.com/test_app
    Enable SP initiated SAML authentication	Checked (enabled)
    IdP SSO Service URL	https://localhost:9443/samlsso
    Sign SP-initiated Authentication Request Enable this to sign the login request	Checked (enabled)
    Do Not Deflate SP-initiated Authentication Request Select this checkbox to disable deflating of requests	Checked
    Authentication Request Signature Method	SHA1

Configuring WSO2 IS

1. Start the IS server and log in to the management console.
2. Navigate to Service Providers>Add under the Main menu and add a new service provider. 
3. Expand the Inbound Authentication Configuration section, then the SAML2 Web SSO Configuration Section and click Configure.

4. In the form that appears, fill out the following configuration details required for single sign-on and click Register.
   
   See the following table for the details. 

   Field	Sample Value	Description
   Issuer	https://workday.com/test_app	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. Ensure that this value is equal to the Service Provider ID set in the Workday configuration.
   Assertion Consumer URL	https://www.workday.com/your.tenant/login-saml.flex	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 honour the ACS URL of the SAML2 request. Tip: The ACS URL must be in the following format: https://www.myworkday.com/<Your workday tenant name>/login-saml.flex
   NameID Format	The default value can be used here.	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.
   Certificate Alias	wso2carbon.cert	Select the public certificate alias of the service provider (See step 8 of the Workday configuration) 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.
   Enable Response Signing	Selected	Select Enable Response Signing to sign the SAML2 Responses returned after the authentication process.
   Enable Signature Validation in Authentication Requests and Logout Requests	Selected	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.
   Enable Single Logout	Selected	Select 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.  Tip: The single logout URL must be in the following format: https://www.myworkday.com/<Your workday tenant name>/logout-saml.flex

5. Click Update to save. 
6. Access the ACS URL from your browser to log in to Workday using the WSO2 Identity Server: https://www.myworkday.com/<Your workday tenant name>/login-saml2.flex.
