SAML Integration for ADFS

Capriza supports single sign-on (SSO) login through SAML 2.0. A SAML 2.0 identity provider (IDP) can take many forms, one of which is a self-hosted Active Directory Federation Services (ADFS) server. ADFS is a service provided by Microsoft as a standard role for Windows Server that provides a web login using existing Active Directory credentials.

Requirements

 

To use ADFS to log into WorkSimple, the following components are required:

  • An Active Directory instance where all users have an email address attribute.

  • A server running Microsoft Server 2012 or 2008. This guide uses screenshots from Server 2012R2, but similar steps should be possible on other versions.

  • A SSL certificate to sign your ADFS login page and the fingerprint for that certificate.

 

After you meet these basic requirements, you need to install ADFS on your server. Configuring and installing ADFS is beyond the scope of this guide, but is detailed in a Microsoft KB article.

 

When you have a fully installed ADFS installation, note down the value for the 'SAML 2.0/W-Federation' URL in the ADFS Endpoints section. If you chose the defaults for the installation, this will be '/adfs/ls/'.

Step 1 - Adding a Relying Party Trust

 

At this point you should be ready to set up the ADFS connection with your Capriza instance. The connection between ADFS and Capriza is defined using a Relying Party Trust (RPT).

 

Select the Relying Party Trusts folder from AD FS Management, and add a new Standard Relying Party Trust from the Actions sidebar. This starts the configuration wizard for a new trust.

 

    1. In the Select Data Source screen, select the last option, Enter Data About the Party Manually.

    1. On the next screen, enter a Display name that you'll recognize in the future, and any notes you want to make.

    1. On the next screen, select the ADFS FS profile radio button.

    1. On the next screen, leave the certificate settings at their defaults.

    1. On the next screen, check the box labeled Enable Support for the SAML 2.0 WebSSO protocol. The service URL will be provided by Capriza, in a format similar to https://api.capriza.com/auth/saml/callback?id=XX
      Note that there's no trailing slash at the end of the URL.

    1. On the next screen, add a Relying party trust identifier of https://api.capriza.com/auth/saml

    1. On the next screen, you may configure multi-factor authentication but this is beyond the scope of this guide.

    1. On the next screen, select the Permit all users to access this relying party radio button.

  1. On the next two screens, the wizard will display an overview of your settings. On the final screen use the Close button to exit and open the Claim Rules editor.


Step 2 - Creating Claim Rules

 

Once the relying party trust has been created, you can create the claim rules and update the RPT with minor changes that aren't set by the wizard. By default the claim rule editor opens once you created the trust. 

  1. To create a new rule, click on Add Rule. Create a Send LDAP Attributes as Claims rule.

  1. On the next screen, using Active Directory as your attribute store, do the following:

    1. From the LDAP Attribute column, select E-Mail Addresses.

    2. From the Outgoing Claim Type, select E-Mail Address.

  1. Click on OK to save the new rule.

  2. Create another new rule by clicking Add Rule, this time selecting Transform an Incoming Claim as the template.

  1. On the next screen:

    1. Select E-mail Address as the Incoming Claim Type.

    2. For Outgoing Claim Type, select Name ID.

    3. For Outgoing Name ID Format, select Email.

    Leave the rule to the default of Pass through all claim values.

  1. Finally, click OK to create the claim rule, and then OK again to finish creating rules.

Step 3 - Adjusting the Trust Settings

 

You still need to adjust a few settings on your relying party trust. To access these settings, select Properties from the Actions sidebar while you have the RPT selected.

 

  1. In the Advanced tab, switch from SHA-256 to SHA-1.

  1. In the Endpoints tab, click on add SAML to add a new endpoint.

  2. For the Endpoint type, select SAML Logout.

  3. For the Binding, choose POST.

  4. For the Trusted URL, create a URL using:

    1. The web address of your ADFS server

    2. The ADFS SAML endpoint you noted earlier

    3. The string '?wa=wsignout1.0'

    The URL should look something like this: https://sso.yourdomain.tld/adfs/ls/?wa=wsignout1.0.  

  1. Confirm your changes by clicking OK on the endpoint and the RPT properties. You should now have a working RPT for Capriza.

Step 4 - Configuring Capriza

 

After setting up ADFS, provide the following information to Capriza:

  • SAML metdata URL (Select Endpoints and look under Metadata for the URL beside the Federation Metadata type.)

or

  1. IdP Login URL

  2. IdP Logout URL (configured in Step 3 above)

  3. x509 Certificate for signing assertions

 

Upon receipt, Capriza will implement this configuration and set up a time to enable and test the integration.
