Login looping when opening the CAC or Analyst

Problem

After installing any Fix Pack from FP2 to FP6, the login prompt is going into a loop. It is working with Planning 10.1.1 RTM on the client machine. Errors : In PlanningErrorLog.csv "Could not logon. Please ensure you can access Cognos Connection using the Gateway URI specified in Cognos Configuration." or "Passport expired" or "Credential Path in Content Manager is invalid. Jobs and Macros will not run until it is reset. Please open the Contributor Admin Console and reset the Credential Path. " In cogserver.log CM-REQ-4342 An error occurred with the client. CM-REQ-4159 Content Manager returned an error in the response header. The error "cmAuthenticateFailed CM-CAM-4005 Unable to authenticate. Check your security directory server connection and confirm the credentials entered at login." can be found in the response SOAP header. In C8ITK.log DPR-ERR-2109 The dispatcher cannot service the request at this time. The dispatcher is still initializing [which is clearly not the case] "HTTP/1.1 500 Erreur Interne de Servlet"
