User unable to login via SSO after changing email to different domain

[sjthiessen]

We're using Authentik as SSO provider. When changing an users mail adress to a mail with a different domain, they won't be able to login again. Error is similar to #4668

{"error":"User authentication aa0cb10e6013efc6d35166b651b76e2e78c6893fd1361b8153643c63ffe782ef already exists for 1021b507-9976-4d43-9afc-61951cd81222, tried to assign to 4cc35fea-5170-4183-b343-e56f303107dc","level":"error","message":"Error during authentication","stack":"Error: User authentication aa0cb10e6013efc6d35166b651b76e2e78c6893fd1361b8153643c63ffe782ef already exists for 1021b507-9976-4d43-9afc-61951cd81222, tried to assign to 4cc35fea-5170-4183-b343-e56f303107dc\n at userProvisioner (/opt/outline/build/server/commands/userProvisioner.js:55:13)\n at process.processTicksAndRejections (node:internal/process/task_queues:95:5)\n at async accountProvisioner (/opt/outline/build/server/commands/accountProvisioner.js:74:12)"}

To Reproduce

Steps to reproduce the behavior:

1. Have a user set up via SSO and with a connected account in outline
2. Change the mail from example@provider.com to example@differentprovider.com
3. (Log out and) log in into outline via SSO again
4. See error

Expected behavior
Changing the mail via SSO should not break the login

Duplicate of #6858 – the best thing you can do is manually update the users email address in the db right now
