This document describes the steps for configuring SSO settings in the Microsoft Entra ID management console.

*For LegalOn's SSO settings, refer to [Set up SSO].

Usage Cases

  • Users in tenants subscribed to the SSO (Single Sign-On) Options

  • Permissions required for configuration: IT Administrator

  • Microsoft Entra ID Configuration / SSO settings Usage Requirements:

    • Tenants subscribed to Microsoft Entra ID

    • Using enterprise applications with Microsoft Entra ID

    • The Email address registered with Microsoft Entra ID matches the Email address registered with LegalOn

*Please contact your company's IT Administrator regarding your Options subscription status.

*If you wish to apply for Options, please inform your sales representative.

Important Notes

  • Current, SAML authentication only supports SP-Initiated SSO (where the Service Provider begins SAML authentication). This requires a Login from the LegalOn login screen each time. Please note that the authentication process will fail with an Error if IdP-Initiated SSO is used.

  • If SSO is enabled in the Status with incorrect settings, closing the browser or Logout will prevent subsequent Logins. After enabling SSO, please ensure you test whether Login is successful by following the "Test Login with SSO " procedure in another browser or in the same browser's incognito mode, while keeping the SSO settings screen Open.
