Summary

Adds Microsoft Entra ID as a server authentication method for Azure Database for PostgreSQL Flexible Server. In server mode, users can sign in through pgAdmin instead of obtaining a database token and entering it as a password.

pgAdmin uses the signed-in account to obtain a PostgreSQL access token for each new physical connection. When the organization requires sign-in again, the server and Query Tool connection dialogs prompt for Microsoft sign-in rather than a PostgreSQL password.

Addresses #9261.

Implementation

  • Add an authentication method field to server registrations, with existing servers defaulting to password authentication.
  • Add Microsoft sign-in through device code, with an optional browser flow for local deployments.
  • Keep token acquisition in a per-user encrypted cache and enforce verified TLS for Entra database connections.
  • Add reconnect prompts, server import/export support, documentation, and regression tests.
  • Keep Entra authentication disabled by default through ENTRA_DB_AUTH_ENABLED.

Verification

  • Connected to Azure PostgreSQL through pgAdmin using Entra ID and confirmed the signed-in database user with SELECT current_user.
  • Connected to the same server using ordinary password authentication and confirmed SELECT current_user, current_database() returned test_admin and postgres.
  • Entra and password regression tests: 15 passed.
  • Server dialog JavaScript tests: 20 passed.
  • Query Tool connection JavaScript tests: 15 passed.
  • Frontend build and git diff --check passed.

Summary by CodeRabbit

  • New Features
    • Server-mode users can connect to Azure Database for PostgreSQL with Microsoft Entra ID when an administrator enables the option.
    • Choose Microsoft Entra ID as the server authentication method and sign in through a browser or device code for remote access.
    • Connections obtain and renew tokens without saving a database password. Sign-in may be required again when organizational policy calls for it.
    • Entra ID connections verify the server’s TLS certificate.
  • Documentation
    • Added setup and sign-in guidance, including supported Azure PostgreSQL hosts and authentication options.

Walkthrough

This change adds configurable Microsoft Entra authentication for Azure Database for PostgreSQL in server mode. It adds server authentication settings, sign-in and token handling, connection prompts, and documentation and tests for the flow.

Changes

Microsoft Entra PostgreSQL authentication

Adds an auth_method field that defaults to password. Server create, update, import, and export paths validate and expose the method. Entra settings clear password-related fields and require full TLS verification.

Adds browser and device-code sign-in and token retrieval for Azure PostgreSQL hosts. Entra connections discard password credentials and use full TLS certificate verification. Tests cover sign-in, token retrieval, connection handling, and destination validation.
Sign-in endpoints and connection challenges
web/pgadmin/browser/server_groups/servers/__init__.py, web/pgadmin/tools/sqleditor/__init__.py, web/pgadmin/utils/tests/test_entra_auth.py
Adds sign-in and device-code endpoints. Entra connection failures return sign-in challenge responses in server and query-tool flows.

Adds Entra controls to server settings and connection prompts. The interface displays device-code instructions and sign-in status, and passes the configured sign-in method to the client.

Merge Risk: 🟡 Moderate · up to 588a8

Entra connections work in the main flow. Query cancel and reset on Entra servers may still fail, and a leftover passfile setting can block an Entra connection. Both should be fixed before merge.

🟠 Major · Pass the Entra token to the query-cancel connection. · connection.py:2014-2031

web/pgadmin/utils/driver/psycopg3/connection.py:2014-2031
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Pass the Entra token to the query-cancel connection.

For Entra authentication, Connection.connect obtains the token from manager.passexec.get() and clears manager.password. cancel_transaction instead passes manager.password to create_connection_string, so the new connection can lack credentials and fail.

🟡 Minor · Use the normalized connection parameters during Entra creation. · __init__.py:1580

web/pgadmin/browser/server_groups/servers/__init__.py:1580
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Use the normalized connection parameters during Entra creation.

When a signed-in user creates an Entra server with connect_now enabled and omits connection_params, the connection branch runs. Entra authentication sets password to None, so the passfile check reads the missing data['connection_params'] key and raises KeyError. The exception handler then deletes the new server registration.

Use the normalized local variable:

🐛 Suggested fix
-                elif 'passfile' in data['connection_params'] and \

🟡 Minor · Remove retained passfile values for Entra authentication. · __init__.py:125-135

web/pgadmin/browser/server_groups/servers/__init__.py:125-135
🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Remove retained passfile values for Entra authentication.

If an Entra server retains connection_params['passfile'], the connection attempt fails before libpq connects. EntraPassword.get() rejects the parameter, so it cannot provide a PostgreSQL password through this path.

Remove passfile while normalizing Entra connection parameters:

🐛 Suggested fix
 def require_entra_ssl(params):
     """A database access token must not be sent on a plaintext connection."""
     params = dict(params or {})
+    params.pop('passfile', None)
     params['sslmode'] = 'verify-full'
     return params
