Test with the SAML test app

You can use our live demo SAML test application. To test your configuration:

• Update the tenant name.
• Update the policy name. For example, use B2C_1A_signup_signin_saml.
• Specify the issuer URI. Use one of the URIs found in the identifierUris element in the application registration manifest. For example, use https://contoso.onmicrosoft.com/app-name.
