Authenticate against Drupal but use the SimpleSAMLphp login page.It's the moment for the drupalauth and DrupalAuth for SimpleSAMLphp projects to shine.Īs per the Drupalauth project documentation, there are two ways to do this: NOTE: We will use Lando throughout this blog post, so I recommend to install it if you want to follow along. Therefore, running lando start will spin off the Docker containers with the LAMP stack and any other fancy configuration for Drupal. I have created two GitHub repositories one for the IDP and another for the SP: On the other hand, we have the SP, another Drupal 9 site, this site won't store any user data and, when users click on login, their login credentials (username and password) will be verified against the IdP. In other words, think of this site as the master site where all the other apps will be connected to in other to login. In our stack, the IdP will be our main Drupal site where all the usernames and passwords will be stored. Of particular interest is a SAML relying party that receives and accepts a SAML assertion issued by a SAML authority. In the SAML domain model, a SAML relying party is any system entity that receives and accepts information from another system entity. Two important examples of SAML authorities are the authentication authority and the attribute authority.Ī SAML service provider is a system entity that receives and accepts authentication assertions in conjunction with a single sign-on (SSO) profile of the Security Assertion Markup Language (SAML). In the SAML domain model, a SAML authority is any system entity that issues SAML assertions. These two concepts are the key components in a SMAL authentication process.Ī SAML identity provider is a system entity that issues authentication assertions in conjunction with a single sign-on (SSO) profile of the Security Assertion Markup Language (SAML). DrupalAuth for SimpleSAMLphp: This is a Drupal module which will handle the connection between Drupal and Simplesaml.Drupalauth: This is a module for the Simplesaml library which will connect Simplesaml with the Drupal user table.We will be also using these two fantastic projects: We will be looking into more details further down the road, but for now, implementing this library will give us that single login for all the applications in our stack. Simplesamlphp is a PHP library that implements the SAML ( Security Assertion Markup Language) open standard. In other words, we will be able to spin off new versions of the site very easily without having to configure or making complex changes in our OS. The great thing about Lando and/or Docker is that help us with a dev stack for stateless applications. This is a great project that uses Docker for creating containers with all the necessary services to run any Drupal application. These Drupal sites will be built with the composer Recommended Project from Drupal:Įnter fullscreen mode Exit fullscreen mode We will need two Drupal 9 websites, the Identity Provider or IdP and the Service Provider or SP. Nevertheless, this blog post will focus on describing how to have one single login between two Drupal sites using the SAML open standard. There are many services out which will give you all the tools you need to have one single login across all your application stack. If you are asking yourself those questions, the answer may be that you need a single sign-on service for your applications. What if the app stack is made with different frameworks or there are other projects linked to your app/website, Does that mean the dev team will have to deal with their own opinionated authentication process as well? However, what happens when there are multiple sites under the same domain/subdomain and there is the need for one single login for all them, Do you have to tell your users to create multiple user accounts on each app/website? Therefore, Drupal, as one of the most popular CMS out there, has their own implementation and opinions about how authentication should be implemented. Authentication is one of the most common features in any web development project.
