To resolve the issue:

1. Log in to the Trend Vision One console, go to Administration > SAML Single Sign-On.
2. Click Download. The Trend Vision One Service Provider metadata XML file downloads to your computer.
3. Configure your Identity Provider (IdP) and download the IdP metadata XML file. For more information, see the topic below for your IdP:
   • Configuring Active Directory Federation Services
   • Configuring Entra ID
   • Configuring Okta
4. Go to Administration> SAML Single Sign-On on the Trend Vision One console, go to Administration > SAML Single Sign-On.
5. Click Upload to locate and upload the IdP metadata XML file to Trend Vision One. SAML single sign-on is configured and you can now add SAML accounts in Trend Vision One.

Once the SAML single sign-on is configured, you can now add SAML accounts in Trend Vision One.
