OpenMethods allows users to log in with a single sign-on (SSO) system using SAML 2.0.
An identity provider (IDP) that supports SAML 2.0 can be set up in various ways, such as a self-hosted Active Directory Federation Services (ADFS) server. ADFS is a Microsoft service that provides web login using existing Active Directory credentials.
This guide uses screenshots from Windows Server 2019 and AD FS Management Version: 10.0.0.0, but you should be able to perform similar steps on other versions.
To begin, you need to install ADFS on your server. However, the installation and configuration of ADFS are beyond the scope of this guide. You can find detailed information about it in this Microsoft article.
During testing, ensure that your workstation authentication is set to the same test email you use for the test. Otherwise, ADFS will not allow you to log in, even if the configuration and profile are correct.
💡 We strongly recommend configuring SSO in your browser's separate incognito mode window. This way, you can keep the session in the standard window, allowing you to switch off the SSO authorization in case of a misconfiguration.
