net-ssh not able to execute command

Why would net-ssh not be able to execute the useradd command?

This is my net-ssh code:

Net::SSH.start(host, user, forward_agent: true) do |ssh|
  ssh.open_channel do |ch|
    ch.request_pty
    ch.exec "mkdir /tmp/unicorn"
    ch.exec "sudo groupadd unicorn"
    ch.exec "sudo chgrp unicorn /tmp/unicorn"
    ch.exec "sudo useradd application" do |ch, success|
      if success
        puts 'command worked'
      else
        puts 'command failed'
      end
    end
  end
end

All of the commands work except for the useradd command. I can log in and run the useradd command and a user is added.

Thanks, Eric

I would modify your script to add the command

puts ch.exec "sudo which useradd"

To see if it is a path problem.

I would also add 

ch.exec 'sudo useradd application 1>/tmp/useradd.log 2>&1'

And then go look on the target box to see if there were any errors logged in the /tmp/useradd.log file.
