Tutorial: Microsoft Entra single sign-on (SSO) integration with Oktopost SAML

In this tutorial, you'll learn how to integrate Oktopost SAML with Microsoft Entra ID. When you integrate Oktopost SAML with Microsoft Entra ID, you can:

  • Control in Microsoft Entra ID who has access to Oktopost SAML.
  • Enable your users to be automatically signed-in to Oktopost SAML with their Microsoft Entra accounts.
  • Manage your accounts in one central location.

Prerequisites

To get started, you need the following items:

  • A Microsoft Entra subscription. If you don't have a subscription, you can get a free account.
  • Oktopost SAML single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Microsoft Entra SSO in a test environment.

  • Oktopost SAML supports SP and IDP initiated SSO

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

To configure the integration of Oktopost SAML into Microsoft Entra ID, you need to add Oktopost SAML from the gallery to your list of managed SaaS apps.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
  2. Browse to Identity > Applications > Enterprise applications > New application.
  3. In the Add from the gallery section, type Oktopost SAML in the search box.
  4. Select Oktopost SAML from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Alternatively, you can also use the Enterprise App Configuration Wizard. In this wizard, you can add an application to your tenant, add users/groups to the app, assign roles, as well as walk through the SSO configuration as well. Learn more about Microsoft 365 wizards.

Test SSO

In this section, you test your Microsoft Entra single sign-on configuration with following options.

SP initiated:

  • Click on Test this application, this will redirect to Oktopost SAML Sign on URL where you can initiate the login flow.

  • Go to Oktopost SAML Sign-on URL directly and initiate the login flow from there.

IDP initiated:

  • Click on Test this application, and you should be automatically signed in to the Oktopost SAML for which you set up the SSO

You can also use Microsoft My Apps to test the application in any mode. When you click the Oktopost SAML tile in the My Apps, if configured in SP mode you would be redirected to the application sign on page for initiating the login flow and if configured in IDP mode, you should be automatically signed in to the Oktopost SAML for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.
