Configuring Web authentication from PacketShaper against Clearpass. This currently works with Clearpass 6.3.x and 6.4.x versions. 


Configure Bluecoat for TACACS or Radius authentication and set the authentication method to ASCII or PAP.


  • Add PacketShaper as an network device under Configuraitonà Network à Devices with appropriate shared secret
  • From Clearpass import the  Shell.xml file which has 'access' and 'role' attribute amended to the default shell dictionary (Refer Answers section for creating this file).  This shall be imported under Policy ManageràAdministrationà DictionaryàTACACS+ Serviceà Import option.
  • Create a new 'TACACS+ Based Enforcement profile' with 'Shell' service selected and service attribute as "Type-Shell | Name- access | Value- touch". Save the newly created enforcement profile. 
  • Map this created enforcement profile under service enforcement policies. 

​​Below is a sample service configuration:
