Stuck on Permission denied page when group membership is enabled

[blucompassai]

Describe the bug
When using google groups to authorize users for certain upstream services , if a user outside the google group try to login , it gets "Permission denied" error. But if i want to login now with another user there is no way to sign in as other user , even after closing the browser , unless i clear the cookies in the browser.

To Reproduce
Steps to reproduce the behavior:

• Go to the sso protected application which is using google groups in gsuite for authorization
• Try to login with a user which is "not" in the authorized google groups.
• You will get "Permission Denied" "Group membership required" error.
• there is no "sign out" button on this screen.
• Try to refresh this screen , will get to "sign in" button
• Hitting "sign in" button will lead to "bad request"
• Now there is no way to login with other user in this browser window until we clear the cookies.

Expected behavior
On the permission denied page i think there should be a "sign out" button

Screenshots

Desktop (please complete the following information):

• Windows 10
• Browser chrome

Additional context
I tried hitting "/signout" on the application and it kind of solve it a bit but just wondering if there is better way through some configuration settings.
