take a look at the template(), inline_template() and generate() function:

                path    => "/usr/bin:/usr/sbin:/bin",
                creates => [
"puppet:///myuser/files/$username/id_rsa" ,
"puppet:///myuser/files/$username/id_rsa.pub" ],
                command =>
generate("/bin/bash","/etc/puppet/manifests/myusers/sshkeygen.bash"
)
        }

At least the following things are wrong/do not work as you seem to 
expect it:

   * The generate() function is run on the master while compiling the
     catalog.
   * The exec then tries to execute the stdout of the script on the
     client.
   * The "creates" parameter avoids running the command when the
     specified files exist. This only checks local files and not
     puppet:/// urls.

Best Regards, David

I use this inside the class

generate("/bin/bash","/etc/puppet/manifests/myusers/sshkeygen.bash")

and I am generating a key inside the server but the permission of the folder
must be: user: puppet group: puppet
