Single Sign on (SSO) for Salesforce with Microsoft Azure AD

Reading Time: 7 minutes

What is SSO?

SSO is an abbreviation of Single Sign-On. It is a method for granting access of multiple applications to users with singe login credentials. The third-party software is used in Integration with Salesforce. The SSO method is extremely helpful in authentication of multiple apps with same details. The third-party tool can be customized according to your organization.

Why should we use SSO?

SSO is an amazing tool that offers its users with security and convenience. Here are some advantages it provides

  • The functionality to login using credentials of any Salesforce trusted third party.
  • It eliminates the need for login for every application.
  • Allows the users to move seamlessly between applications and Salesforce org without requiring repeated logins.
  • It allows configuration of SSO depending on the use case so users can access the Salesforce org from a third-party application like a corporate portal.
  • You can set up SSO and allow users to login in to another application using your Salesforce org.
  • You can configure an SSO chain allowing uses to login to a third-party application to access Salesforce and use the access to login to another org.
  • It allows you to configure a log in experience that is less centralized and users get to login to multiple apps using same credentials.

Implementation

The article explains on how to setup SSO for Salesforce using already existing Azure AD setup.

Assumptions

User should exist in Azure. Or User should be created in Azure AD first. It is assumed that licenses for both Azure AD and Salesforce are already in place.

Concerns & Issues

Configuring SSO can be complicated, and both the service providers should be well mapped in user entity. Requires two party license and hence not cost effective.
