Auth0 Fails to Display Default Application for SAML IdP Initiated SSO Connection Due to Entity Limit

Last Updated: Jun 18, 2026

Overview

In the tenant dashboard, when a tenant has more than 100 applications, some applications will fail to display due to the entity display limit of 100. Preventing updates using this method. Execute a PATCH request via the Auth0 Management API to manually assign the default application and resolve the issue.

Applies To

Auth0
Security Assertion Markup Language (SAML)
SAML Identity Provider (IdP)
Initiated Single Sign-On (SSO)
Management API
Enterprise Connections

Cause

The error occurs because the Auth0 Admin Console drop-down menu only displays the first 100 applications for the tenant. If the target application falls outside this limit, it cannot be selected via the user interface.

Solution

How is the default application assigned when the entity limit is exceeded?

To assign the default application for the SAML IdP initiated SSO connection, execute a PATCH request using the Auth0 Management API with the required configuration payload.

Execute a GET request to the https://{tenantDomain}/api/v2/connections/{id} endpoint to retrieve the existing client configuration and copy the signingCert value.
Construct a PATCH request to the Auth0 Management API Update a connection endpoint.

Include the following JSON payload in the request body, replacing the placeholder values with the specific tenant details.

//Make sure to preserve the entire existing options field JSON payload 
//during the PATCH request in order to not overwrite other existing 
//configurations besides the ones needed

{
  "options": {
    "signInEndpoint": "<idp_sign_in_url>",
    "idpinitiated": {
      "client_id": "<client_id>",
      "client_protocol": "saml",
      "client_authorizequery": ""
    },
    "signingCert": "<copied_from_GET>"
  }
}

Execute the request to update the default application.
