Ssh less lab issue

Please check this screenshots , I have done for thor user password less authentication for stapp01,stapp02 and stapp03

You have to do passwordless ssh in app server with their respective sudo user but you did without specifying sudo user.
thor --> jump_host
tony --> stapp01
steve --> stapp02
banner --> stapp03

thor@jump_host /$: ssh tony@stapp01
