This document provides a configuration example of Security Assertion Markup Language (SAML) Authentication on FTD managed over FMC. The configuration allow Anyconnect users to establish a VPN session authenticating with a SAML Identity Service Provider.

Prerequisites

Azure VPN Gateway. View All 6 Integrations. Claim Cisco AnyConnect and update features and information. This is a setup by step instructions on how to create your Win32 App for Cisco AnyConnect Secure Mobility Client v4.9.040403 + SBL.Instructions:1. Mar 15, 2021 Approach 2: YubiKey TOTP with Cisco AnyConnect and Azure AD via SAML This approach is based on the capabilities in Cisco ASA and the AnyConnect client to leverage Azure AD’s SAML SSO functionality. In this approach Azure AD acts as a SAML Identity Provided (IdP) and the Cisco ASA server acts as a Service Provider (SP) which validates the SAML.

Requirements

Cisco recommends that you have knowledge of these topics:

  • Knowledge of Anyconnect configuration on FMC
  • Knowledge of SAML and metatada.xml values

Components Used

The information in this document is based on these software and hardware versions:

  • Firepower Threat Defense (FTD) version 6.7.0
  • Firepower Management Center (FMC) version 6.7.0
  • ADFS from AD Server with SAML 2.0

Note: If possible, use a NTP server to synchronize time between the FTD and IdP. Otherwise, make sure the time is manually synchronized between them.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Background Information

Some of the current limitations for SAML are:

  • SAML on either ASA or FTD is supported for Authentication only, for authorization you can use an external AAA server with protocols such Radius or LDAP
  • Having SAML authentication attributes available in DAP evaluation (similar to RADIUS attributes sent in RADIUS auth response from AAA server) is not supported
  • ASA supports SAML enabled tunnel-group on DAP policy. However, you cannot check the username attribute while using SAML authentication, because the username attribute is masked by the SAML Identity provider
  • More limitations or SAML are described in the below link. These limitations apply to ASA and FTD: 'Guidelines and Limitations for SAML 2.0 '

Note: All the SAML configuration that needs to be implemented on the FTD, can be found on the metadata.xml file provided by your IdP.

Configuration

This section describes how to configure Anyconnect with SAML authentication on FTD

Azure

Get the SAML IdP parameters

The below image shows a SAML IdP metadata.xml file. From the output, you can get all values needed in order to configure the Anyconnect profile using SAML:

Configuration on the FTD via FMC

Step 1. Install and enroll the IdP certificate on the FMC. Navigate to Devices > Certificates

Step 2. Click Add. Select the FTD where you want to enroll this certificate. Under Cert Enrollment, click on the + sign

In the Add Cert Enrollment section, use any name as label for the IdP cert. Make sure you click on Manual. Check the CA Only and Skip Check for CA flag fields, Then, paste the base64 format IdP CA cert. Finally, click on Save and then on Add

Step 3. Configure the SAML server settings. Navigate to Objects > Object Management > AAA Servers > Single Sign-on Server. Then, select Add Single Sing-on Server

Step 4. Based on the metadata.xml file already provided by your IdP, configure the SAML values on the New Single Sign-on Server

Step 5. Configure the Connection Profile that uses this authentication method. Navigate to Devices > Remote Access and then edit your existing VPN Remote Access configuration

Step 6. Click on the + sign and add another Connection Profile

Step 7. Create the new Connection Profile and add the proper VPN local pool or DHCP Server

Step 8. Now, select the AAA tab. Under the Authentication Method option, select SAML. Under the the Authentication Server option, select the SAML object created on Step 4

Step 9. Finally, create a group-alias to map the connections to this Connection Profile. This is the tag that users can see on the Anyconnect Software drop-down menu. Once this is configured, select OK and save the complete SAML Authentication VPN configuration

Step 10. Navigate to Deploy > Deployment and select the proper FTD in order to apply the SAML Authentication VPN changes

Step 11. Now, provide the FTD's metadata.xml file to the IdP so they add the FTD as a trusted devic. On the FTD CLI, run the command: 'show saml metadata SAML_TG ' where SAML_TG is the name of our Connection Profile created on Step 7.

As seen in the below bracket, this is the expected output from the command mentioned above:

Once the metadata.xml from the FTD is provided to the IdP and they add it as a trusted device, test under the VPN connection can be done.

Verify

Verify if the VPN Anyconnect connection was established using SAML as authentication method with the commands seen below:

Troubleshoot

Some verification commands on the FTD CLI can be used to troubleshoot SAML and Remote Access VPN connection as seen in the bracket:

Note: You can troubleshoot DART from the Anyconnect's user PC as well

In this tutorial, you'll learn how to integrate Cisco AnyConnect with Azure Active Directory (Azure AD). When you integrate Cisco AnyConnect with Azure AD, you can:

Azure Anyconnect Training

  • Control in Azure AD who has access to Cisco AnyConnect.
  • Enable your users to be automatically signed-in to Cisco AnyConnect with their Azure AD accounts.
  • Manage your accounts in one central location - the Azure portal.

Prerequisites

To get started, you need the following items:

Cisco Anyconnect Saml Azure Ad

  • An Azure AD subscription. If you don't have a subscription, you can get a free account.
  • Cisco AnyConnect single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Azure AD SSO in a test environment.

  • Cisco AnyConnect supports IDP initiated SSO

Adding Cisco AnyConnect from the gallery

To configure the integration of Cisco AnyConnect into Azure AD, you need to add Cisco AnyConnect from the gallery to your list of managed SaaS apps.

  1. Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
  2. On the left navigation pane, select the Azure Active Directory service.
  3. Navigate to Enterprise Applications and then select All Applications.
  4. To add new application, select New application.

If you would like to on board multiple TGTs of the server then you need to add multiple instance of the Cisco AnyConnect application from the gallery. Also you can choose to upload your own certificate in Azure AD for all these application instances. That way you can have same certificate for the applications but you can configure different Identifier and Reply URL for every application.

Create an Azure AD test user

In this section, you'll create a test user in the Azure portal called B.Simon.

  1. From the left pane in the Azure portal, select Azure Active Directory, select Users, and then select All users.
  2. Select New user at the top of the screen.
  3. In the User properties, follow these steps:
    1. In the Name field, enter B.Simon.
    2. In the User name field, enter the username@companydomain.extension. For example, B.Simon@contoso.com.
    3. Select the Show password check box, and then write down the value that's displayed in the Password box.
    4. Click Create.

Assign the Azure AD test user

In this section, you'll enable B.Simon to use Azure single sign-on by granting access to Cisco AnyConnect.

  1. In the Azure portal, select Enterprise Applications, and then select All applications.
  2. In the applications list, select Cisco AnyConnect.

  7. In the Add Assignment dialog, click the Assign button.

Configure Cisco AnyConnect SSO

  1. You are going to do this on the CLI first, you might come back through and do an ASDM walk-through at another time.

  2. Connect to your VPN Appliance, you are going to be using an ASA running 9.8 code train, and your VPN clients will be 4.6+.

  3. First you will create a Trustpoint and import our SAML cert.

  4. The following commands will provision your SAML IdP.

  5. Now you can apply SAML Authentication to a VPN Tunnel Configuration.

    Note

    There is a feature with the SAML IdP configuration - If you make changes to the IdP config you need to remove the saml identity-provider config from your Tunnel Group and re-apply it for the changes to become effective.

Create Cisco AnyConnect test user

In this section, you create a user called Britta Simon in Cisco AnyConnect. Work with Cisco AnyConnect support team to add the users in the Cisco AnyConnect platform. Users must be created and activated before you use single sign-on.

Test SSO

In this section, you test your Azure AD single sign-on configuration with following options.

Anyconnect
  • Click on Test this application in Azure portal and you should be automatically signed in to the Cisco AnyConnect for which you set up the SSO
  • You can use Microsoft Access Panel. When you click the Cisco AnyConnect tile in the Access Panel, you should be automatically signed in to the Cisco AnyConnect for which you set up the SSO. For more information about the Access Panel, see Introduction to the Access Panel.
