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. 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. Select the ls application and double-click Authentication. 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 prompted, enter in a username and password (remember to use Bob’s account). Open the ADFS management wizard.

The default AD FS site uses a feature called Extended Protection that by default isn’t compatible with Chrome. Self-signed certificates are convenient for testing and development. Setup is complete. This rule uses a custom script to get all the groups from the temporary claim () and then uses the name of the group to create the principal/role pair, which has this format: arn:aws:iam:123456789012:saml-provider/ADFS,arn:aws:iam:123456789012:role/ADFS-.

Nothing left but to click Close to finish. One use case I demonstrated was enterprise federation to AWS using Windows Active Directory (AD), Active Directory Federation Services (ADFS) 2.0, and SAML (Security Assertion Markup Language) 2.0. When you have the SAML metadata document, you can create the SAML provider in AWS. When using this approach, your security group naming convention must start with an identifier (for example, AWS-). If you are just getting started with federating access to your AWS accounts, we recommend that you evaluate AWS SSO for this purpose. Preface. Similarly, ADFS has to be configured to trust AWS as a relying party. You can use SAML mapping to assign users licenses, groups, and roles based on their ADFS configuration. Unlike the two previous claims, here I used custom rules to send role attributes. If you want to follow along with my configuration, do this: 1. WAP functions as a reverse proxy and an Active Directory Federation Services [AD FS] proxy to pre-authenticate user access. Next, include the 12-digit AWS account number.

Finally, add the matching role name within the AWS account. 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. You’ll need the ARNs later when you configure claims in the IdP. Select a role and then click Sign In. 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.

Add Bob to the AWS-Production and AWS-Dev groups. 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. I set up my environment as a federation server using the default settings. Know of a better way? 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 couple sections cover installing and configuring ADFS. 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. This is one half of the trust relationship, where the ADFS server is trusted as an identity provider. Depending on the browser Bob is using, he might be prompted for his AD username and password.

He starts at an internal web site and ends up at the AWS Management Console, without ever having to supply any AWS credentials. These techniques are still valid and useful. 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. If a user is associated with multiple Active Directory groups and AWS accounts, they will see a list of roles by AWS account and will have the option to choose which role to assume. 1. Give Bob an email address (e.g., email@example.com). 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. I named the two roles ADFS-Production and ADFS-Dev. Follow these steps to configure the OAuth provider in Dynamics 365 … If you don’t have a certificate, you can create a self-signed certificate using IIS. 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-). The metadata XML file is a standard SAML metadata document that describes AWS as a relying party. This is where you use it. Next, update the Roles AD FS claim rule that you created earlier, by using the following code. The sign-on page authenticates Bob against AD. 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. 2. 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.

Bob’s browser posts the SAML assertion to the AWS sign-in endpoint for SAML (https://signin.aws.amazon.com/saml). I must have ended up mangling the relationship between VS and IIS Express by deleting the localhost certificate. Before you create a SAML provider, you need to download the SAML metadata document for your ADFS federation server. Here is an example. If you’ve never done this, I recommend taking a look at the IAM user guide. Ever since I published this blog post, some readers have asked how to configure the AD FS claims using multiple AWS accounts. 4. If you’re using Chrome as your browser, you need to configure the browser to work with AD FS. And since Windows Server includes ADFS, it makes sense that you might use ADFS as your IdP.

Note: Remember that if you’re following along with this description, you need to use exactly the same names that we use. Federation using SAML requires setting up two-way trust. I configured this by returning to the AD FS Management Console. You are redirected to the Amazon Web Services Sign-In page. If you’re using a locally signed certificate from IIS, you might get a certificate warning. (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.). The Windows Server 2008 R2 I used came with an older version of ADFS. To recreate my setup, perform the following: 1. Update from January 17, 2018: The techniques demonstrated in this blog post relate to traditional SAML federation for AWS. Chrome and Firefox do not support the Extended Protection of ADFS (IE does). This new claim rule limits scope to only Active Directory security groups that begin with AWS- and any twelve-digit number. Those of you with multiple AWS accounts can leverage AD FS and SSO without adding claim rules for each account. In the preceding section I created a SAML provider and some IAM roles. 3. At this year’s re:Invent I had the opportunity to present on the topic of delegating access to your AWS environment. My EC2 instance used Windows Server 2008 R2 running Internet Information Server (IIS), AD, and 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 If you already have ADFS in your environment, you may want to skip ahead to the Configuring AWS section. Create another user named ADFSSVC. I was really stuck. You’re done configuring AWS as a relying party. In the example, I used an account number of 123456789012. Select (check) Form Based Authentication on the Intranet tab. 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. If you want follow along with my description, you’re going to need a Windows domain. ** 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. This will distinguish your AWS groups from others within the organization. With my accounts and groups set up, I moved on to installing ADFS. The claim rule then constructs the SAML assertion in the proper format using the AWS account number and the role name from the Active Directory group name. In the Add Relying Party Trust Wizard, click Start. They are the complement to the AD groups created earlier. If you’re using any browser except Chrome, you’re ready to test—skip ahead to the testing steps. In your domain, browse to the following address: https://localhost/adfs/ls/IdpInitiatedSignOn.aspx. 2. 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.
