Provisioning fails on 4.8.0 on FreeBSD

[Timur I. Bakeyev]

Hi!

I know that AD DC provisioning was crippled on FreeBSD for quite a while,so
I tried once again with the hope that in 4.8.0 the situation has changed.
Well, now I got quite  anew error message while trying:

# /usr/local/bin/samba-tool domain provision --realm 'DOMAIN.FREEBSD'
--domain 'DOMAIN' --dns-backend 'SAMBA_INTERNAL'  --server-role 'dc'

    self.add(msg, controls)

So, what do I miss and where I can increase the buffer size?
