Bug description

I copied the issue incorrectly reported into documentation here: https://github.com/nextcloud/documentation/issues/9727

Actual behaviour After login to Nextcloud using web browser, all app tokens (WebDAV and Nexcloud sync client) don't work.

Steps to reproduce
  1. Create app token for WebDAV connection and login to sync client 2.6.2
  2. Change password in Active Directory
Expected behavior

Starting with Nextcloud 15 For password changes in external user backends the device-specific passwords are marked as invalid and once a login of the user account with the main password happens all device-specific passwords are updated and work again.

Research direction

Start by reproducing the issue with an LDAP/Active Directory account, an app token for WebDAV or the sync client, and a password change in Active Directory. Trace the app-token login after the user logs in with the main password. Done means device-specific passwords are refreshed and work again as described for Nextcloud 15 and later.
