I was thinking this too. I don't know why NTLM would need a userdb at all. It
should just use something like ntlm_auth (which is configured in
auth_winbind_helper).
What if I simply removed the userdb? What would you recommend for userdb, passdb?

$ wbinfo -u

These are all the AD users (most obfuscated for a bit of security). I am testing
with user mark.

Unless the Samba provision did something to nnswitch, I've done nothing; nor
have I seen anything in the Samba or dovecot wikis suggesting changes. Remember
also that the Samba4 AD/DC works perfectly with redirected folders and users
logging on to any Windows workstations, and works perfectly with things wanting
"Windows Authentication" like SQLserver, so the "Windows Authentication" does
work at some level. My /etc/nsswitch.conf is:
passwd: compat
group: compat
hosts: files dns
networks: files
services: files
protocols: files
rpc: files
ethers: files
netmasks: files
netgroup: files
bootparams: files
automount: files
aliases: files

Yeah, I can't seem to find a soul on the planet who has actually done this. If I
get it figured out I'll post with a suggestion to Timo to wiki-ize it.
I'm a bit puzzled that no one appears to have done this. I would think that a
Samba4 AD/DC in a office environment with lots of Windows workstations running
Outlook would be about the most common environment there is; especially now that
Small Business Server is no longer sold and Server Essentials does not support
Exchange. What are all the SBS/Exchange/Outlook small businesses doing? Limping
along with SBS2008/11, or putting their email in Outlook.com? Seems like the
Samba4/dovecot/Outlook combo would be an ideal migration.
I appreciate your help.
