OAuth2 Duplicate User Error

[philsjh]

Describe the bug

• I have GitHub OAuth2 set up as a federation provider in Authentik with the user:read, and user:email scopes. The configuration is set up to match on email addresses, but I have also tried username and UPN and a few other options.
• I have an application tied to an access group which my user is added to.
• The application uses the GitHub OAuth2 configuration as an authentication source.
• I log in via GitHub and arrive on the user dashboard.
• I can see the application on the user dashboard.
• I click on the application, and it sends me to log in again (despite the fact I'm already logged in)
• When I log in via GitHub SSO, I get "Server Error" and on checking the logs it appears to be trying to create the user again, despite the fact I'm already logged in.

Relevant info
version 2024.8.2
