Issue/Introduction

We're running Policy Server, when ACE authentication Scheme is in use, the 
Policy Server doesn't communicate with the RSA Server and Policy 
Server reports error : 

  [4708/4456][Wed Jan 24 2018 16:38:30][SmAuthAceHtml.cpp:1127] 
  [ERROR][sm-LoginLogout-01130] AceCheck:Denied---aceRetVal = 1 

So the user cannot get authenticated. How can we resolve this ?

Environment

Resolution

The issue was with the node secret. On the RSA Server, we clicked
on "clear the node secret" check-box from RSA security console and then,
the Policy Server could authenticate the user successfully against the
RSA Server.
