The feature was demoed on our regular community demos, you can find it at https://www.youtube.com/watch?v=QfANwMzxebE&feature=youtu.be&t=119

@Timo, would you mind covering it in the Foreman manual too? I think it would be beneficial for more users.

Ok, i watched the demo and learned that i need to use the provisioning snippet 'create_users' for this.
After provisioning, my public key is on the new host but i have issues with the format of the key in autorized_keys file.

I copied my public key into Foreman as following:

[key type] [key] [comment]
ssh-rsa AAA...== Dimitrij Artes

In the authorized_keys file i see the following:

[key type] [key type] [key] [comment] [comment]
ssh-rsa ssh-rsa AAA...== Dimitrij Artes [username]@[foreman fqdn]

If i copy my key to Foreman without key type i get the error 'Fingerprint could not be generated Length could not be calculated'.
If i let the comment blank i get
ssh-rsa ssh-rsa AAA...== [username]@[foreman fqdn]

The biggest problem is the double key type wich caused failure in the structure of the key in authorized_keys file.
How should i paste my key in Foreman?

The template shipped with 1.15.0 contains a bug. Please see https://github.com/theforeman/community-templates/pull/392 for a fixed version.

Sounds good to me, please feel free to put it in community-templates 1.15 for 1.15.2

I've applied the fix and it work now. Thanks!

What about the comment? At the moment the key comment is overwritten with user@foreman_fqdn.

You could use something like this:

<%-     index = 0 -%>
  <%-     user.ssh_keys.each do |key| -%>
  <%-       if index == 0 -%>
  <%=        key %>
  <%-       else -%>
  <%=        "#{key} - #{index}" %>
  <%-       end -%>
  <%-       index += 1 -%>
  <%-     end -%>

or more easy:

 <%-     user.ssh_keys.each do |key| -%>
 <%=      key %>
 <%-     end -%>
