Single Sign-On With SAML

Overview

Configuring Single Sign-On (SSO) involves details that vary based on provider and customer environment, these settings are strict and must be at the knowledge of the administrator configuring the connection. 

If SSO is a new concept, it may take time and multiple attempts to accurately configure all of the identifying data and settings, allowing for secure and reliable authentication. An administrator with experience in SSO or the IT infrastructure of the organization can help streamline the process.

The Decisions Support team is available to help, but may not be able to answer questions or solve problems that are unique to a customer organization.

Version 7 Endpoints

Below is a list of endpoints used for version 7, along with an example for the endpoints.

AD Sync and SSO

Example

This example will demonstrate how to configure Single Sign-On using the SAML module.

1. Navigate to the System> Settings. Right-click SAML Settings and select Edit.
   
2. In the Edit SAML Setting window, check the Enabled option. Then, under Identity Providers section, select ADD.
   
   
3. Configure the appropriate fields in the Add Identity Providers window. This information is based on the SSO provider information used for the organization. When complete, click OK.
   
   

   Setting Name	Description
   Display Name	Name for Identity Provider
   Login URL	The SSO login of the Identity Provider
   Logout URL	The SSO logout URL of the Identity Provider
   Sign Logout Requests/Responses	When set to true, logouts will be signed with a private certificate.
   Logout Signature Algorithm	RSA-SHA1 and RSA-SHA256 are the available signature algorithms.
   Filename of PFX File	Path to the private cert file on the server's filesystem.
   Password for PFX	Password for the private cert
   IdP Issuer/Entity ID	The ID of the identity provider. This value is only required to allow initiated logins.
   SP Issuer/Entity ID	Usually, the Base URL to the Decisions Portal. The Portal Base URL can be found by clicking the Profile icon in the Designer Studio, then selecting About from the menu.
   Name ID Policy	Either email or transient ID based on Identity Provider
   X.509 Certificate	The PEM formatted string of the X.509 cert
   Process If User Not Found	When enabled, the selected Flow will be run if a user with an unknown ID tries to log in. This Flow is typically used to create the unknown user in the Decisions Portal so that they can log in. Users can choose to pick a Flow or create the Flow Behavior SAML User Not Found Flow.
   Processing Type	Set to Run Flow In Background.
   Pick Flow	This is the Flow that will be run when an unknown user tries logging in. The default Flow can be used for creating unknown users. It is named SAMLDefaultCreateAccount.
   Retry Login After	When set to true, the System will try to log in the user after running the selected Flow. If the Flow creates the user, it should be set to be true so that the user seamlessly gets logged in, or else they would have to try logging in a second time to get in.

   
   
4. In the Edit SAML Settings window, click the dropdown list under Primary Identity Provider and select the created Identity Provider. Click SAVE to save SAML Settings.
   

   
   

   When using a SAML Login Flow from the option Run Flow on Each Login, Relay State is available as input in the Flow Designer on the Data Explorer panel. Auto Timeout should only be used with the built-in SignOn. In the HTML Portal, log out the user so that they go back to their SSO Sign-in Page. To get Attributes passed in from the SAML Response, navigate to the Data Explorer panel then SAML Response > Assertion > AttributeStatement.
   
5. Navigate to System > Security > Accounts and right-click an account that should be able to use SAML SSO. Select Edit Account.
   
6. In the Edit Entity window, locate the PERSONAL INFORMATION section and define the User Identifier value. This value should be used as the value for the Identity Provider to send as the User Id. Click SAVE.
   
7. Once at least one admin user is enabled to work with SSO, open the Settings.xml file located at C:\Program Files\Decisions\Decisions Services Manager.
   
8. Find the line <EnableSingleSignOn>false</EnableSingleSignOn> and set the value to true. Save changes to the file. 
   If the line is not present, add the line to the Settings.xml file.

   <EnableSingleSignOn>true</EnableSingleSignOn>

   
   

9. Restart the Decisions Server service to enable SAML SSO mode. 

Metadata

Using Email Address nameId Policy

When Identity Provider is using Email Address nameId Policy, use the following code:

$metadata['http://myDecisionsServer.Decisions.com/decisions'] = array(
'AssertionConsumerService' => 'AssertionConsumerService' => 'http://myDecisionsServer.Decisions.com/decisions/Primary/SAML/AssertionConsumer', 'SingleLogoutService' => 'http://myDecisionsServer.Decisions.com/decisions/Primary/Logout',
'NameIDFormat' => ***'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress'***	  
);

Using Transient namedId Policy

When Identity Provider is using Transient nameId Policy, use the following code:

$metadata['http://myDecisionsServer.Decisions.com/decisions'] = array(
'AssertionConsumerService' => 'http://myDecisionsServer.Decisions.com/decisions/Primary/SAML/AssertionConsumer', 'SingleLogoutService' => 'http://myDecisionsServer.Decisions.com/decisions/Primary/Logout',
'NameIDFormat' => ***'urn:oasis:names:tc:SAML:2.0:nameid-format:transient'***	  
);
