Duo Protection for Samanage

Duo offers a variety of methods for adding two-factor authentication and flexible security policies to Samanage SSO logins, complete with inline self-service enrollment and authentication prompt.

Overview

As business applications move from on-premises to cloud hosted solutions, users experience password fatigue due to disparate logons for different applications. Single sign-on (SSO) technologies seek to unify identities across systems and reduce the number of different credentials a user has to remember or input to gain access to resources.

While SSO is convenient for users, it presents new security challenges. If a user's primary password is compromised, attackers may be able to gain access to multiple resources. In addition, as sensitive information makes its way to cloud-hosted services it is even more important to secure access by implementing two-factor authentication.

Duo Access Gateway

Duo Access Gateway (DAG), our on-premises SSO product, layers Duo's strong authentication and flexible policy engine on top of Samanage logins using the Security Assertion Markup Language (SAML) 2.0 authentication standard. Duo Access Gateway authenticates your users using existing on-premises or cloud-based directory credentials and prompts for two-factor authentication before permitting access to Samanage.

Duo Access Gateway is part of the Duo Beyond and Duo Access plans, so you can define policies that enforce unique controls for each individual SSO application. For example, you can require that Salesforce users complete two-factor authentication at every login, but only once every seven days when accessing Samanage. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Deploy Duo Access Gateway

  1. Install Duo Access Gateway on a server in your DMZ. Follow our instructions for deploying the server, configuring DAG settings, and adding your primary authentication source.

  2. Add the attributes from the table below that correspond to the Duo attributes Mail attribute and Username attribute in the "Attributes" field when configuring your Active Directory or OpenLDAP authentication source in the DAG admin console, separated by a comma. For example, if Active Directory is your authentication source, enter mail,sAMAccountName in the "Attributes" field.

    Duo Attribute Active Directory OpenLDAP
    Mail attribute mail mail
    Username attribute sAMAccountName uid

    If your organization uses other directory attributes than the ones listed here then enter those attribute names instead. If you've already configured the attributes list for another cloud service provider, append these additional attributes to the list.

  3. After completing the initial DAG configuration steps, click Applications on the left side of the Duo Access Gateway admin console.

  4. Scroll down the Applications page to the Metadata section. This is the information you need to provide to Samanage when configuring SSO. Click the Download Certificate link to obtain the token signing certificate (the downloaded file is named "dag.crt").

    DAG Metadata Information

Enable Samanage SSO

Add the Duo Access Gateway as a new single sign-on provider for Samanage.

  1. Log on to Samanage as an administrative user and navigate to DashboardSetupSingle Sign-On.

  2. Once on the "Single Sign-On" page check the Enable Single Sign-On with SAML box. The page automatically expands to display the SSO options.

  3. Copy the SSO URL information from the Duo Access Gateway admin console Metadata display and paste it into the Samanage Identity Provider URL field.

    Example: https://yourserver.example.com/dag/saml2/idp/SSOService.php

  4. Copy the Logout URL information from the Duo Access Gateway admin console Metadata display and paste it into the Samanage Logout URL field.

    Example: https://yourserver.example.com/dag/saml2/idp/SingleLogoutService.php

  5. Leave the Error URL field blank.

  6. Leave the SAML Issuer field at the default value of SAManage.com.

  7. The "Identity Provider x.509 Certificate" is the DAG Metadata certificate supplied by Duo Access Gateway. Open the dag.crt file in a text editor (like Notepad), and copy the entire contents of the file (including the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- lines). Paste the certificate file text into this field.

  8. Check the Redirect to the saml login page when logging into Samanage by default option.

  9. After you've entered all the required information click Update.

Create the Samanage Application in Duo

  1. Log on to the Duo Admin Panel and navigate to Applications.

  2. Click Protect an Application, locate SAML - Samanage in the applications list, and click Protect this Application. See Getting Started for help.

  3. The Domain name is the subdomain used when logging into your company's Samanage. For example, if your Samanage login URL is yourdomain.samanage.com then enter yourdomain as the subdomain name in Duo.

  4. Samanage uses the Mail attribute when authenticating. We've mapped Mail attribute to DAG supported authentication source attributes as follows:

    Duo Attribute Active Directory OpenLDAP SAML IdP Google Azure
    Mail attribute mail mail mail email mail

    If you are using a non-standard email attribute for your authentication source, check the Custom attributes box and enter the name of the attribute you wish to use instead.

  5. Click Save Configuration to generate a downloadable configuration file.

    Duo Samanage Application Settings

  6. You can adjust additional settings for your new SAML application at this time — like changing the application's name from the default value, enabling self-service, or assigning a group policy — or come back and change the application's policies and settings after you finish SSO setup. If you do update any settings, click the Save Changes button when done.

  7. Click the Download your configuration file link to obtain the Samanage application settings (as a JSON file).

    Important: This file contains information that uniquely identifies this application to Duo. Secure this file as you would any other sensitive or password information. Don't share it with unauthorized individuals or email it to anyone under any circumstances!

Add the Samanage Application to Duo Access Gateway

  1. Return to the Applications page of the DAG admin console session.

  2. Click the Choose File button in the "Add Application" section of the page and locate the Samanage SAML application JSON file you downloaded from the Duo Admin Panel earlier. Click the Upload button after selecting the JSON configuration file.

  3. The Samanage SAML application is added.

Verify SSO

You can log on to Samanage using your organization’s domain login page e.g. https://yourdomain.samanage.com. This redirects to the Duo Access Gateway login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected back to the Samanage site after authenticating.

DAG Login and Authentication Prompt

Congratulations! Your Samanage users now authenticate using Duo Access Gateway.

Microsoft AD FS

Microsoft's Active Directory Federation Services (AD FS) is a popular choice for SSO because it easily integrates with the AD identity store many organizations already have deployed. Duo's support for cloud applications and SSO drops in to an existing AD FS installation to provide secondary authentication after a user passes primary authentication (successful Active Directory logon).

If you don't already have AD federation running the first step is to install and configure Microsoft AD FS in your organization. Microsoft's Deployment Guides for AD FS versions 2.0, 2.1, and 3.0 are available on the TechNet site.

Once your AD FS services are up and running, the second step is to configure the SSO partnership between your AD FS service and the external cloud resource, in this case Samanage. Learn more about configuring Samanage SSO with AD FS at the Samanage SSO Blog.

After you have successfully configured and tested AD FS SSO login to Samanage using your AD domain credentials, you can then install the Duo AD FS integration. AD FS protection is included with Duo's paid plans.

With the Duo integration for AD FS installed, users pass primary authentication to the AD FS service as usual. Once primary authentication succeeds, users are forwarded to the Duo service for secondary authentication. After approving logon using one of Duo's authentication methods, the user is fully logged in to Samanage.

Other Identity Partners

Using a third-party SSO provider for cloud application access? Duo partners with leading cloud SSO providers like Okta and OneLogin to secure access with our strong and flexible authentication platform.

You can also use Duo two-factor authentication with CAS and Shibboleth on-premises IdPs.
