Technician unable to login in

Hello,
 After upgrading to build 9326, we have a technician who cannot login to ServiceDesk.
 We have refreshed his internet setting in Internet Explorer and he still gets the error.
  NTLM Failing: Redirecting To Login Page. He enters his username and password and it fails.

 We have the SSO setup.

 Other techs are having no issues connecting.

 We have tried opening ServiceDesk in Firefox and Google Chrome and same issue.

Thank you.
