I'm new with Rundeck and completely amazed with it and I'm trying to execute a job and my scenario is detailed below:

• Rundeck is configured with ssh passwordless authentication for user master between node Server (rundeck server) and node Target (remote Solaris host) for user "master"
• In node Target I want to execute a script /app/acme/stopApp.sh with a user appmanager

• Normally and manually, when I need to run script above I proceed with

  ssh master@server 
  sudo su - appmanager
  

  or simply

  ssh -t master@server 'sudo su - appmanager'
  

  works without password and finally run (as appmanager)

  /app/acme/stopApp.sh
  

But I'm not sure how can I reproduce these steps using Rundeck. I read in some previous messages that for each job line rundeck use a new ssh connection, so the workflow below always fails for me with the messages:

sudo: no tty present and no askpass program specified
Remote command failed with exit status 1

Please someone could help me with some information to solve this issue.

Without this functionality I wouldn't be able to introduce a little DevOps in my department.

I read the user guide and admin guide but I couldn't find an easy example, neither in this forum, to follow.
