[noce2]

This will be on the Auth0 non-prod tenant

• An Auth0 repository is setup to enable allow deploys from Github as per docs here
• Set up a rule in Auth0 where it makes a post call to the /organisations/{}/users endpoint prior to returning a token to the web UI. here
• Auth0 adds the appropriate permissions returned in the response from the User Account Service to the IDToken as a custom claim, as described here
• Auth0 appropriately handles any login failures as per login flow diagram
• Auth0 makes calls to the User Account Service via the API Gateway with an API Key

@aakano684 , all tenants have been set up with GitHub integration. When we're ready to commit to a particular rule etc (after testing via the UI or something), we'll need to raise a PR against the master branch for us to deploy said change.

In terms of tenant to use for this story, let's keep it scoped to one of the 5. Say, the local-mathdojo-non-production.

PRs need to be done to enable the Auth0 rules in pre-prod, prod and local-non prod
