The SSTP protocol makes the VPN configuration much easier as the configuration of the firewall needs to open only SSL over Http … Unlike the two previous claims, here I used custom rules to send role attributes. This is one half of the trust relationship, where the ADFS server is trusted as an identity provider. Select Create a new Federation Service. If you’re using a locally signed certificate from IIS, you might get a certificate warning. I used the names of these groups to create Amazon Resource Names (ARNs) of IAM roles in my AWS account (i.e., those that start with AWS-). Ever since I published this blog post, some readers have asked how to configure the AD FS claims using multiple AWS accounts. Jamie’s solution follows. In the Edit Claim Rules for  dialog box, click Add Rule. Open the ADFS management wizard. Select (check) Form Based Authentication on the Intranet tab. In the Add Relying Party Trust Wizard, click Start. You’re done configuring AWS as a relying party. (If you are mapped to only a single IAM role, you skip the role selection step and are automatically signed into the AWS Management Console.). 5. 7. Want more AWS Security how-to content, news, and feature announcements? Configure AD LDS-Claims Based Authentication; Configuring ADFS … This is where you use it. WAP functions as a reverse proxy and an Active Directory Federation Services [AD FS] proxy to pre-authenticate user access. In some cases I encountered the following error message: It turns out this is a known issue that can be fixed by running the following at the command line. Find the ARNs for the SAML provider and for the roles that you created and record them. If prompted, enter in a username and password (remember to use Bob’s account). He starts at an internal web site and ends up at the AWS Management Console, without ever having to supply any AWS credentials. Feel free to post comments below or start a thread in the Identity and Access Management forum. On my instance, I had an existing certificate I could use. If you’re using Chrome as your browser, you need to configure the browser to work with AD FS. For demonstration purposes, I used a single user (Bob) who is a member of two AD groups (AWS-Production and AWS-Dev) and a service account (ADFSSVC) used by ADFS. The presentation must have struck a nerve, because a number of folks approached me afterwards and asked me if I could publish my configuration—hence the inspiration for this post. Distributed, SaaS, and security solutions to plan, develop, test, secure, release, monitor, and manage enterprise digital services Expand: , Sites, Default Web Site, and adfs. During the SAML authentication process in AWS, these IAM roles will be matched by name to the AD groups (AWS-Production and AWS-Dev) via ADFS claim rules. You’ll need the ARNs later when you configure claims in the IdP. This will distinguish your AWS groups from others within the organization. Almost there – just need to confirm your settings and click Next. You are redirected to the Amazon Web Services Sign-In page. Finally, add the matching role name within the AWS account. If you use Active Directory Federation Services (AD FS) and want to secure cloud or on-premises resources, you can configure Azure Multi-Factor Authentication Server to work with AD FS. If you’ve never done this, I recommend taking a look at the IAM user guide. If you already have ADFS in your environment, you may want to skip ahead to the Configuring AWS section. Once again the IAM documentation has a great walkthrough of these steps, so I won’t repeat them here. If the command is successful, you see output like this: You’ve finished configuring AD FS. To set up my domain, I used Amazon EC2 because that made it easy to access the domain from anywhere. When you’re done, click Next. Similarly, ADFS has to be configured to trust AWS as a relying party. As part of this ongoing commitment, please review our updated. Select an SSL certificate. Select Sign in to one of the following sites, select Amazon Web Services from the list, and then click Continue to Sign In. If you’re using any browser except Chrome, you’re ready to test—skip ahead to the testing steps. 2. Before we get too far into the configuration details, let’s walk through how this all works. Select Authentication Policies > Primary Authentication > Global Settings > Authentication Methods > Edit. You can configure your account to login via Single Sign-On (SSO) with Active Directory Federation Services (ADFS). 4. This new claim rule limits scope to only Active Directory security groups that begin with AWS- and any twelve-digit number. Know of a better way? If you are unable to log in using Chrome or Firefox, and are seeing an 'Audit Failure' event with "Status: 0xc000035b" in the Event Viewer on the ADFS server, you will need to turn off Extended Protection. From the ADFS Management Console, right-click ADFS 2.0 and select Add Relying Party Trust. ** If you would like to implement federated API and CLI access using SAML 2.0 and ADFS, check out this blog post from AWS Senior IT Transformation Consultant Quint Van Deman. When you have the SAML metadata document, you can create the SAML provider in AWS. When ADFS is launched, it looks like this: To launch the configuration wizard, you click AD FS 2.0 Federation Server Configuration Wizard. And since Windows Server includes ADFS, it makes sense that you might use ADFS as your IdP. The first step is to create a SAML provider. With my accounts and groups set up, I moved on to installing ADFS. Self-signed certificates are convenient for testing and development. In this post I describe the use case for enterprise federation, describe how the integration between ADFS and AWS works, and then provide the setup details that I used for my re:Invent demo. The next step is to configure ADFS. Setup is complete. The next step is to configure the AWS end of things. I created two roles using the Grant Web Single Sign-On (WebSSO) access to SAML providers role wizard template and specified the ADFS SAML provider that I just created. If so, skip ahead to the Configuring AWS section. Copyright ©2021 Zoom Video Communications, Inc. All rights reserved. Select the ls application and double-click Authentication. If you missed my session and you’re interested in hearing my talk, you can catch the recording or view my slides. After downloading the package, you launch the ADFS setup wizard by double-clicking AdfsSetup.exe. 4. Bob’s browser receives a SAML assertion in the form of an authentication response from ADFS. [RESOLVED] Exchange 2016 IIS not usable after installation from CU5; April (4) Microsoft Exchange 2007 reached end of life today.NET Framework 4.7 released but not yet supported on Exchange 2016.NET Framework 4.7 released but not yet supported on Skype for Business From Bob’s perspective, the process happens transparently. Configure the OAuth provider. To recreate my setup, perform the following: 1. I was really stuck. Nothing left but to click Close to finish. I named the two roles ADFS-Production and ADFS-Dev. Create another user named ADFSSVC. Create two AD Groups named AWS-Production and AWS-Dev. Chrome and Firefox do not support the Extended Protection of ADFS (IE does). At Zoom, we are hard at work to provide you with the best 24x7 global support experience during this pandemic. Please add a comment to this post. I’m interested in hearing your feedback on this. Preface. 6.   Review your settings and then click Next. Follow us on Twitter. 4. By default, you can download it from following address: https:///FederationMetadata/2007-06/FederationMetadata.xml. If you are just getting started with federating access to your AWS accounts, we recommend that you evaluate AWS SSO for this purpose. 3. To test, visit http://YOURVANITY.zoom.us and select Login. Read more about Single Sign-On. Note that the names of the AD groups both start with AWS-. I named my SAML provider ADFS. Unable to log in using Google Chrome or Firefox. The default AD FS site uses a feature called Extended Protection that by default isn’t compatible with Chrome. This account will be used as the ADFS service account later on. Add Bob to the AWS-Production and AWS-Dev groups. This is done by retrieving all the authenticated user’s AD groups and then matching the groups that start with to IAM roles of a similar name. This new feature enables federated single sign-on (SSO), which lets users sign into the AWS Management Console or make programmatic calls to AWS APIs by using assertions from a SAML-compliant identity provider (IdP) like ADFS. In the preceding section I created a SAML provider and some IAM roles. If you don’t already have one, I recommend that you take advantage of the CloudFormation template I mentioned earlier to quickly launch an Amazon EC2 Windows instance as a Windows AD domain controller. Microsoft Web Application Proxy [WAP] is a new service added in Windows Server 2012 R2 that allows you to access web applications from outside your network. Next, update the Roles AD FS claim rule that you created earlier, by using the following code. Here’s how I did it. However, it’s easy to turn off extended protection for the ADFS->LS website: 1. Depending on the browser Bob is using, he might be prompted for his AD username and password. The sign-on page authenticates Bob against AD. The screenshots show the process. They are the complement to the AD groups created earlier. I use this in the next rule to transform the groups into IAM role ARNs. If you want to follow along with my configuration, do this: 1. Behind the scenes, sign-in uses the. These techniques are still valid and useful. Make sure that you name the IAM roles ADFS-Production and ADFS-Dev. Do these names look familiar? When using this approach, your security group naming convention must start with an identifier (for example, AWS-). Update from January 17, 2018: The techniques demonstrated in this blog post relate to traditional SAML federation for AWS. Give Bob an email address (e.g., bob@example.com). If you don’t have a certificate, you can create a self-signed certificate using IIS. That’s one reason I used Windows AD with ADFS as one of my re:Invent demos. (Make sure you run the command window as an administrator.). This is significant, because Bob’s permission to sign in to AWS will be based on a match of group names that start with AWS-, as I’ll explain later. All AWS accounts must be configured with the same IdP name (in this case ADFS) as described in the “Configuring AWS” section earlier in this post. 2. Now that we understand how it works, let’s take a look at setting it all up. AWS recently added support for SAML, an open standard used by many identity providers. Citrix Gateway presents all hosted, SaaS, web, enterprise, and mobile applications to users on any device and any browser. You can use SAML mapping to assign users licenses, groups, and roles based on their ADFS configuration. Configure My Sites - Step by Step Guide; Create User Profile Service Application; Configure Secure Store Service Application; Create BCS Service Application; Usage and Health Data Collection; How to Create State Service Application; Authentication / Security. If you want to do the same, I encourage you to use a nifty CloudFormation template that creates a Windows instance and sets up a domain for you. 6. Note: Remember that if you’re following along with this description, you need to use exactly the same names that we use. Configure AD LDS-Claims Based Authentication; Configuring ADFS … The metadata XML file is a standard SAML metadata document that describes AWS as a relying party. Remember the service account I mentioned earlier? When I finished creating the SAML provider, I created two IAM roles. If you want follow along with my description, you’re going to need a Windows domain. This configuration triggers two-step verification for high-value endpoints. However, AWS Single Sign-On (AWS SSO) provides analogous capabilities by way of a managed service. Choose your authorization rules. If all goes well you get a report with all successful configurations. Any users with membership in the Active Directory security group will now be able to authenticate to AWS using their Active Directory credentials and assume the matching AWS role. Next, include the 12-digit AWS account number. By the way, this post is fairly long. I must have ended up mangling the relationship between VS and IIS Express by deleting the localhost certificate. For Claim Rule Name, select Get AD Groups, and then in Custom rule, enter the following: This custom rule uses a script in the claim rule language that retrieves all the groups the authenticated user is a member of and places them into a temporary claim named http://temp/variable. *Note: if the SP Entity ID in Zoom is set to, https://YOURVANITY.zoom.us/saml/metadata/sp, How to enable TLS 1.2 on an ADFS Server (Windows Server 2012 R2), https://[SERVER]/adfs/ls/idpinitiatedsignon.aspx?logintoRP=[Vanity].zoom.us, Business or Education Account with Zoom with approved, Find and download/view your ADFS XML metadata at https://[SERVER]/FederationMetadata/2007-06/FederationMetadata.xml, In the left panel, navigate to Sites > Default Web Site > ADFS > LS. Note that is the name of the service account I used. In these steps we’re going to add the claim rules so that the elements AWS requires and ADFS doesn’t provide by default (NameId, RoleSessionName, and Roles) are added to the SAML authentication response. (Think of this as a variable you can access later.)
