Use the cookies SSO authentication flow #193
Description
What: Use the cookies SSO authentication flow
Why: We implemented a new shared cookie that has the session for the current user. We want to use this instead of the current SSO flow implemented with the original Discourse SSO Provider.
With the current implementation, there's an issue with the session going out of sync. With the cookies based one, this issue should be resolved.
How:
- Change the session code to read from the Discourse shared cookie.
- Remove the code related to the original Discourse SSO implementation
- Make sure session out of sync errors are fixed after this change
