After switching from Forms Authentication to Windows Integrated Authentication, the "Logout" icon in the top right hand corner of the Archive Manager website is now missing.
This behaviour is by design, Windows Integrated Authentication will always use the credentials of the locally logged on user so the "Logout" icon is not required.
1. Closing the browser will exit the session. There is no need to Logout.
2. Launch the Archive Manager Website and Windows Integrated Authentication uses the locally logged on credentials for the new session.
