</div>This indeed work if one defines its own template.<br>
I'd like however to automate SSH Key and/or other files setup help with<br>
user id.<br>
<br>
I expect to create a template as admin and allow "use" with ACL to users.<br>
This default template makes a copy of user key etc.... help with<br>
CONTEXT/FILES.<br>
<br>
Using variables is ok only if user defines his own template. But for<br>
most of my users, honestly, defining a template would be quite obscur.....<br>
