This article clarifies whether a Security Assertion Markup Language (SAML) enterprise connection is compatible with the device authorization flow in a native application. It addresses an issue where an error occurs when an enterprise connection is the only configured connection for a tenant.

no connections configured/enabled

• Auth0
• Device Authorization Flow
• Enterprise Connections
• Security Assertion Markup Language (SAML)

The issue occurs because the login configuration is set to "Identifier + Password". This profile is typically paired with a database connection to handle passwords. When a SAML connection is the only option, a valid login form cannot be rendered because the system cannot find a compatible connection for the "Identifier + Password" flow.

To resolve the error and enable the login flow with an enterprise-only setup, perform one of the following procedures.

Option 1: Switch to Identifier First

1. Navigate to the Auth0 dashboard.
2. Select Authentication.
3. Select Universal Login.
4. Go to the Settings tab.
5. Locate the Experience section.
6. Change the login flow to Identifier First.
7. Select Save. NOTE: This allows the user to enter an email address so the system can redirect them to the SAML Identity Provider (IdP) through Home Realm Discovery.

Option 2: Enable Connection as a Button

1. Navigate to the Auth0 dashboard.
2. Select Authentication.
3. Select Enterprise.
4. Select SAML.
5. Select the specific SAML connection.
6. Go to the Login Experience tab.
7. Enable the Display connection as a button option.
8. Select Save.

NOTE: This allows the user to bypass the input field by clicking the SAML provider button directly.
