Hi,
I have simply registered an APP with the single tenant option:

After the APP is registered, I added me who is the GLOBAL ADMINISTRATOR to this app. This app appears in https://myapps.microsoft.com/. However when I click it, I get: "App with ID <> is not configured for single sign-on. For more help, contact your admin". While searching for the solution, I came across: https://learn.microsoft.com/en-us/entra/identity/enterprise-apps/add-application-portal-setup-sso#enable-single-sign-on. I followed this article. However, the "SINGLE SIGN-ON" blade does not give me "Set Up Single Sign-on with SAML" option. I just get:

Why is this? I have Entra ID P1, P2 licenses. How can I get rid off this error?

Thanks in advance.

    Hello @A M ANISUL HUQ ,

    Thank you for posting your query on Microsoft Q&A.

    Based on your description, it seems you have created a custom application and are attempting to configure Single Sign-On (SSO). When you created the application through the App Registrations blade in Azure, you noticed there was no option to set up SSO.

    This is because applications created via App Registrations are intended for OAuth or OIDC protocols. If your application supports these protocols, you need to configure it through the App Registrations blade.

    However, if your application supports the SAML protocol, you should create and configure the application through the Enterprise Applications blade.

    This behavior is expected. The correct approach for your custom application depends on the protocol it supports:

    • For OAuth or OIDC: Use App Registrations to configure your application.
    • For SAML: Use Enterprise Applications to set up and configure Single Sign-On.

    Steps to Configure SAML-based SSO:

    1. Go to Microsoft Entra ID.
    2. Navigate to Enterprise Applications.
    3. Click on New Application.
    4. Select Create your own application.
    5. Choose **Integrate any other application you don't find in the gallery (Non-gallery).
    6. After creating the application, go to the Single Sign-On section and configure SSO as needed.
