This document describes an issue where you receive an "HTTP Status 401" error message after a period of inactivity when you use Single Sign-On (SSO).
Cisco recommends that you have knowledge of these topics:
Active Directory Federation Service (AD FS)
This document is not restricted to specific software or hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
When you use SSO, you can receive a "401" error after a period of inactivity, instead of a prompt to log in again as shown in the image.
The only way for you to be able to log in again is to close the entire web browser and reopen it.
This is caused by a mismatch in the timeout values between CloudCenter and the SSO server.
