Research direction

Start with the /logout and /oauth2/logout entry points and trace how LOG_AUTHENTICATED_USER adds usernames to request logs. Reproduce both logout flows with the setting enabled, then add or update coverage for the expected access-log username. Done means both logout requests log the authenticated username before the session ends.

Describe the bug

Hello,

sine the new feature to log authenticated user has been done here, it seems that when you logout, username is not displayed in log.

Here an example with logout from oauth2:

1.2.3.4 - - [11/Sep/2026:06:37:07 +0000] "GET /oauth2/logout?next=/browser/ HTTP/1.1" 302 6269 "https://pgadmin4.youpi.fr/browser/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/152.0.0.0 Safari/537.36"

Here an example with "classical" logout:

1.2.3.4 - - [11/Sep/2026:06:34:21 +0000] "GET /logout?next=/browser/ HTTP/1.1" 302 205 "https://pgadmin4.youpi.fr/browser/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/152.0.0.0 Safari/537.36"

To Reproduce
Deploy pgadmin4 and enable LOG_AUTHENTICATED_USER, click on Logout button.

Expected behavior

Add missing username in log:

1.2.3.4 - me@youpi.fr [11/Sep/2026:06:34:21 +0000] "GET /logout?next=/browser/ HTTP/1.1" 302 205 "https://pgadmin4.youpi.fr/browser/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/152.0.0.0 Safari/537.36"

Desktop (please complete the following information):

  • OS: Kubernetes 1.34.8
