The plugin does not log users out of the Casdoor application when they log out of WordPress.
For example, if your WordPress site is site.com and your Casdoor application is hosted at casdoor.com:
When you log out from site.com, and then visit casdoor.com, you'll notice that you're still logged in there.
Please add an option to automatically log out from casdoor.com when a user logs out from site.com.
