Description
When react applications are deployed to differing subdomains each application maintains its own unsynchronised login state. When also working with grails applications and plain HTML pages the login/logout state is inconsistent at best, misleading at worst. The current workaround degrades further if using the new auth service.
Task
- Add a new SSO service to manage tokens.
- Add a method for a central logout.
- Add a method to use this service for the react applications in this project.
- Add a method to use this service for grails applications.
