How to Unblock Your Users and retain SSO authentication

To restore or ensure stable authentication, you must switch from the "global identifier" to a "domain-specific identifier" by following these two steps:

Step 1: Update Settings in Egnyte

1. Log in to your Egnyte domain as an Administrator.
2. Navigate to Settings > Configuration > Security & Authentication.
3. Locate your SAML Single Sign-On configuration.
4. Find the setting "Use domain-specific issuer value" and set it to Enabled (or "On")
5. Save your changes

Step 2: Update Settings in Microsoft Entra (Azure AD)

1. Log in to your Microsoft Entra admin center.
2. Go to Enterprise Applications and select your Egnyte application.
3. Navigate to Single Sign-On settings.
4. Under Basic SAML Configuration, locate the Identifier (Entity ID).
5. Replace the global value https://saml-auth.egnyte.com/ with your specific domain URL: https://<your-domain>.egnyte.com/ or custom access URL (if any).
6. Save the configuration in Microsoft Entra.
