I got mine yesterday.  As sthen@ pointed out, this device would support working 
with umb(4).  Using the following AT commands to switch into mbim mode:

AT+CUSBPIDSWITCH=9003,1,1
AT+CLANMODE=1

You also need to apply the following diff, thanks.

Active Directory Support

2021-09-23 Thread Tyler Montney
I am trying to get OpenBSD working with Active Directory. I want to do
this because I am setting up a mail server (OpenSMTPD and Dovecot).
I want the mail server to support 2FA, which can be done through AD.
For AD support, I've followed:

https://serverfault.com/questions/20202/
authenticating-openbsd-against-active-directory
https://www.whatsmykarma.com/blog/?p=685

Everything is fine until I SSH into the box. I've added a user
with adduser (such as "mydomainuser"). I expect to then be able
to SSH in as "mydomainuser" because login.conf will check
Kerberos first, then the host. Getting access denied.

Of course, all of this might be an XY problem. If you know
of a better way to implement 2FA in my situation, please tell.

Hax0rz of the early 2020s why are you looking so round up?

Without posture there's no movement.
