Issue/Introduction

Change has been made to response "WebAgent_HHTP-Header_Variable" ---- GETSSOTICKET and after a the change was reverted the response is failing to produce a SSO Session ticket.

Environment

Policy Server Version :  12.8sp1
Webagent Version : 12.52.104 Siteminder Web Agent

Resolution

The fix was to load a new Secret= for the WebAgent-HTTP-Header-Variable and put the same secret in the Auth Scheme that is being used for that response. 

After those updates were made the Policy server was rebooted and the replay attack was resolved.
