Single Sign-On – Windows Azure Setup

Single Sign-on (SSO) permits a user to use a set of login credentials set up in one Identity Provider (IdP) application to access Service Provider applications which significantly simplifies the login process. This feature is extremely useful for enterprise-level companies that use multiple software platforms on a daily basis and need better user-account management.

Kurtosys is an SSO provider which means users can log into the Kurtosys platform and Kurtosys portals using their credentials from other applications that use the common SAML 2.0 authentication protocol. This eliminates the need for users to set up and remember multiple passwords, thus reducing password fatigue and improving security.

Setting up Microsoft Azure as the Identity Provider (IdP)

The set up for the Kurtosys App to use Azure for Single Sign-On (SSO), and the set up for Azure must be done simultaneously so that the information required to complete both setups is available.

  1. Log in to portal.azure.com.
  2. Search for Enterprise applications. This is where Azure is set up as the Identity Provider (IdP) for SSO.

  1. Click + New Application to create the SSO application.

  1. Click + Create your own application.

  1. In the panel that slides out on the right, give your application a name e.g. SSO – Kurtosys.
  2. Select the Integrate any other application you don’t find in the gallery option.
  3. Click Create.

A notification will pop up that the application is being created; this could take a few minutes.

When the application is complete, it will be displayed on your screen.

  1. Click the Set up single sign on button.

  1. Click SAML to specify the single sign-on method.

Some of the information displayed will be needed for the Kurtosys App SSO setup, and some of the information produced during the Kurtosys App SSO setup will be needed for Azure.

Setting up Single Sign-On for Microsoft Azure in Kurtosys App

  1. Click the System Administration cog.
  1. Click Authentication.
