For us, we ran into this same problem when we were domain joining MacBooks (Airs/Pros) that have no wired connection. We needed to have the Wifi connection available for the initial logon for the User. What we do is have a configuration profile that connects to our Enterprise Wifi with the machine Active Directory Account then switches over once the user logs in. This makes the wireless connection available to us before a user login.

For the couple of 2016 MBPt's we have: we netboot to image, login to AD, and give our users the iClever USB-C ethernet and 3-port USB3 hub. Has worked well so far.

@mellamo could you please provide details on how your WIFI configuration profile is configured, I'm planning on implementing that in our company.

thank you in advance.

@mellamo Could you provide more detail on how your configuration profile is setup. I had no idea you could do that and login to Wifi with a machine AD account.

@cbooker We are using the usb-c adapters as well.

You can see this article; it is a little outdated for Lion, but this is pretty close: https://www.afp548.com/2012/11/20/802-1x-eaptls-machine-auth-mtlion-adcerts/

@mellamo Could you please provide details n how your WIFI configuration profile is configured, I'm really interested.

have a great day!

I have been able to successfully get this to work now after a lot more research. Turns out the key ingredient that I was missing from my network config profile was the certificates. Make sure you add your AD network certificates to the payload of the config profile and mark them as trusted in the trust tab next to protocols. After I made this change I was able to login via wifi with a new user account without the network cable plugged in.

@cbooker I see you're using LEAP/PEAP; at the time your above profile is installing, is the machine then already bound to the domain? I'm assuming that would be required for the "Use Directory Authentication" bit to work, if this is installed as a Computer-level profile (but how did you bind then if you're not connected)? Or, does the connection use the users' credentials from their login to authenticate to the wireless (RADIUS?)?

@cbooker Thank you very much!

@KSchroeder Yes, the MacBook Pro is already bound to the domain. And you would need that first for the "Use Directory Authentication" to work. We don't have problems with binding to AD while connected and I don't mind doing that since it is a one time ordeal. But our laptops here get used by multiple users. And requiring each new laptop user to plug into the network to login for the first time became problem-matic. This makes my life a lot easier and makes things more seemless for the users.
