Hi @zmsoft
To add users from different domains to Azure Databricks, you need to ensure that those users are part of the Microsoft Entra ID (formerly Azure AD) tenant associated with your Databricks workspace.
User is in a Different Domain but within the Same Microsoft Entra ID Tenant:
If the user belongs to a different domain but is already part of your Microsoft Entra ID tenant, you can add them directly:
- Sign in to Azure Databricks as an Account Admin.
- Open the Account Console.
- In the sidebar, click User Management.
- Go to the Users tab and click Add User.
- Enter the user's name and email address.
- Click Add User to complete the process.
Once added, you can assign them to a workspace using the Workspace Admin Settings page. If Identity Federation is enabled, you can manage access at the account level.
User is Not Part of Your Microsoft Entra ID Tenant:
If the user is not in your Microsoft Entra ID tenant, you must first invite them as a Guest User before adding them to Databricks:
- Go to Azure Portal → Open Microsoft Entra ID.
- Navigate to Users → Click New Guest User.
- Enter the user’s email address (from the external domain).
- Send the invitation, and the user must accept it to join your tenant.
Once added to Microsoft Entra ID, follow the steps in Scenario 1 to add them to Databricks.
This ensures the user can authenticate and access the Databricks workspace securely.
