[Samba] ldapsam cannot find NT password hash




Hello!

I've been digging at this one for several days now, and haven't been
able to figure out what's going on. Google searches haven't been
particularly helpful, so maybe I am searching the wrong words.

My LDAP server has the proper schema, and I have an attribute for my
user: https://imgur.com/VRbM7s9 (yeah I know the password hash is there,
but I don't care, because this won't exist)

It shows up in pdbedit -L

root@freenas[~]# pdbedit -L

butts:90000004:butts <-- this one

However, the NtPassword hash does not show up in pdbedit -L -vw

All authentication attempts either from windows or from linux smbclient
result in NT_STATUS_WRONG_PASSWORD
Logs: https://hastebin.com/cexudifino.js (ignore the silly extensions)

I'm very confused as to what's going on. When I debug my LDAP server, I
never see a query to load the NT password hash, but I do see attribute
requests for all the other elements here.

I'm hoping that this is a simple configuration problem, but I'm not sure.

Running on FreeNAS 11 and my smb.conf (via testparm -v) is here

Thanks in advance for your help!
