The integration lets you use AWS IAM Identity Center groups to not only grant access to create a Client VPN connection, but also to allow access to specific network ranges based upon group membership. We’ve taken the guesswork out of the process and show you the exact mappings needed for the Client VPN to AWS IAM Identity Center integration. Deploying custom SAML applications can present some challenges, specifically around the mapping of attributes between what the SP expects to receive and what the IdP can provide. Users authenticate with the IdP once using a single set of credentials, and then have access to multiple applications and services without additional sign-ins.Ĭlient VPN supports identity federation with SAML 2.0 for Client VPN endpoints. With SAML, you can enable a single sign-on experience for your users across many SAML-enabled applications and services. The IdP authenticates users and passes their identity and security information to the SP via SAML. You can then use Security Assertion Markup Language 2.0 (SAML 2.0) to integrate AWS IAM Identity Center with each of your resources or applications, also known as service providers (SPs). A common way to solve this challenge is to use a central identity store such as AWS IAM Identity Center, which functions as your identity provider (IdP). Maintaining a separate set of credentials to authenticate users and authorize access for each resource is not only tedious, it’s not scalable. In this blog post, we show you how you can integrate Client VPN with your existing AWS IAM Identity Center via a custom SAML 2.0 application to authenticate and authorize your Client VPN connections and traffic.
