Missing Blocked Account Notification Emails Due to Duplicate Email Addresses

This article explains why "Blocked Account" notification emails are not sent when using an Ext-Directory database connection, which is a custom database configuration used to authenticate users against an external data store.

The issue occurs when this connection is configured to allow multiple user accounts to share the same email address.

• Ext-Directory database connection
• Brute-force protection
• Email notifications

To resolve this issue, migrate the Ext-Directory connection to a unique email model using the following steps:

1. Identify and resolve all duplicate email addresses in the user database.

   • This must be completed before changing settings to prevent user lockout.

2. Sign in to the dashboard.

3. Choose Connections > Database and select the Ext-Directory connection.

4. Clear the Requires Username toggle.

   • This configuration ensures the email address serves as the unique identifier.

5. Test user flows, including sign-in, sign-up, and password reset, to verify the migration.
