Lock to AD

Hi,

I today have this string:
<label> [text* your-name placeholder “Best?llare (Obligatoriskt f?lt)”] </label>

Which means that a name needs to be typed into that field, which is great. BUT where the kicker is that you can type in another managers name there or whatever you feel like.

I have an AD plugin added so users can log into the site, is there any way to set so the Contact Form can only be used when you are logged in and that the field is filled in with the ad user-name that is logged in on the site?

The thought here is to end up with that the field is automatically filled in and cannot be spoofed by typing in another persons name..

The page I need help with: [log in to see the link]
