More experimentation ...
I tried removing userdb and passdb from the dovecot NTLM config. That didn't work. I then tried adding a static userdb as follows:
userdb { driver = static # allow_all_users = yes args = gid=100 home=/home/HPRS/%n }
(Interestingly, when I uncommented "allow_all_users" I got an "unsupported setting" [or something like that], even though that was in there from the beginning and is shown in the example wiki http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm)
Anyway, in both tests my error messages were the same:
Sep 08 18:38:16 imap-login: Debug: SSL: elliptic curve secp384r1 will be used for ECDH and ECDHE key exchanges Sep 08 18:38:16 imap-login: Debug: SSL: elliptic curve secp384r1 will be used for ECDH and ECDHE key exchanges Sep 08 18:38:16 auth: Debug: auth client connected (pid=8758) Sep 08 18:38:16 auth: Debug: client in: AUTH 1 NTLM service=imap session=vPWqBUQfeADAqAA6 lip=192.168.0.2 rip=192.168.0.58 lport=143 rport=56184 Sep 08 18:38:16 auth: Debug: client passdb out: CONT 1 Sep 08 18:38:16 auth: Info: ntlm(?,192.168.0.58,<vPWqBUQfeADAqAA6>): user not authenticated: NT_STATUS_LOGON_FAILURE Sep 08 18:38:18 auth: Debug: client passdb out: FAIL 1
Notice that my userid (mark or mark@ohprs) is nowhere to be found. Whereas when I specified the userdb passwd at least it had a user id in the error log. From my previous test with userdb passwd amd passdb shadow:
Sep 05 16:45:19 auth: Debug: client passdb out: OK 1 user=mark@hprs original_user=mark@HPRS Sep 05 16:45:19 auth-worker(5498): Debug: shadow(mark@hprs,192.168.0.58): lookup Sep 05 16:45:19 auth-worker(5498): Info: shadow(mark@hprs,192.168.0.58): unknown user Sep 05 16:45:19 auth: Debug: master userdb out: NOTFOUND 998899713
The "Info: ntml" log entry has ntlm(?,192.168.0.58,<vPWqBUQfeADAqAA6>), whereas the previous test "Info shadow" log entry has Info: shadow(mark@hprs,192.168.0.58).
Of course I have no passdb specified which is right for NTML ... or is it?
I feel like this should be obvious to someone familiar with Dovecot. Once again, it's difficult for me to believe no on on planet Earth (who also happens to subscribe to this list) had ever done Dovecot/ntlm from Outlook before.
Help!!! If I can't get this last bit sorted out I'll be forced back to Server 2012 and Exchange.
Thanks, --Mark

Hmm. I would expect to see 'mark@hprs.com'. Whatever your full domain name is.
Full user@domain would be mark@hprs.local
It also won't look up /etc/shadow - Samba is doing the AD->Unix UID mapping. Your AD users shouldn't be in there when all is said and done.
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?
Well, at when I did a Samba4 install as a DC it still behaved like a Samba3 member, and there were no AD users in the local unix passwd files.
What does wbinfo -u provide? It should list all your users - especially because it's an DC. Whatever wbinfo -u shows, you may need to adjust another config file to match waht Dovecot is receiving.
$ wbinfo -u
Administrator Guest krbtgt dns-mail mark sogo **arr **ress **mith **nee **ris **atterson **armaine **tkeson **mmitoh
These are all the AD users (most obfuscated for a bit of security). I am testing with user mark.
I assume /etc/nsswitch.conf has been modified to use Samba?
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
Sorry I haven't done this, but it doesn't seem like anyone else has either
- so I'm just shooting in the dark here trying to get you steered in the right direction...
Rick
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.

The failed ntlm look-up is looking up user mark@hprs in shadow, which it doesn't find. Is there a way to strip the "@hprs" bit from the user so it can find the correct entry in /etc/shadow? That might fix the problem.

Rick et al,
The link you gave was a start, but is targeted for Samba3 and is assuming a probably Windows [SBS]Server AD/DC separate from the DC hosting dovecot, and includes setting up kerberos.
I'm using a Samba4 AD/DC with integrated kerberos (so I don't think there is any setup I can do there). Nevertheless I've followed the instructions otherwise; specifically adding to 10-auto.conf the following recommended lines:
auth_use_winbind = yes auth_winbind_helper_path = /usr/bin/ntlm_auth mechanisms = plain ntlm login
(Before, my 'mechanisms' were only plain and login). /usr/bin/ntlm_auth has global r/w privilege.
I did not specify the static userdb since these users are configued in /etc/passwd and I thought that would work; example given in link (could that be an issue?):
userdb static { args= uid=501 gid=501 home=/home/vmail/%1Ln/%Ln mail=maildir:/home/vmail/%d/%1Ln/%Ln:INBOX=/home/vmail/%d/%1Ln/%Ln allow_all_users=yes }
This didn't work. Also, existing, working Outlook connections using 'logon' (i.e. the userID and PW are configured in Outlook) stopped working.
I changed a test Outlook client to check the 'Request login using Secure Password Authentication (SPA)' and also checked: More Settings > Outgoing Server
My outgoing server (SMTP) requires authentication' and 'Use same settings as
my incoming mail server'. Note that on the "Change Account" dialog (where the SPA checkbox is) the 'User Name' and 'Password' retained their values and were not grayed out as I would have expected if using AD authentication.
After doing the above and clicking 'Test Account Settings' I was re-promted to enter a password - also not expected. At bottom are the Dovecot log message I received after doing the 'Test Account Settings'.
Surely, connecting from an Outlook client to Dovecot on a Samba4 AD/DC should be a very common implementation. Has someone done this successfully?
Immediately below is my doveconf -n and below that the dovecot log messages.

Hi Mark,
I haven't done it, but I've played with the scenario enough to have an idea.
What you want to do is have Outlook auth via NTLM to Dovecot.
First that means having the machine be a domain member (usually via Samba) in order to properly process NTLM/Kerberos handshake - which it appears you have. Second that means having Dovecot know how to accept NTLM authentication (SPA) to pass to the Samba backend.
A 'Dovecot NTLM' search led me here: http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm
What's not on the page that I'd expect to see, are the compile-time requirements for inclucing samba/kerberos libs within Dovecot. If it doesn't 'just work' with the config changes in the wiki, you may need to recompile with the right features.
Also - check the permissions of the ntlm_auth program. That's caused many issues with Radius installs, IIRC.
Hope that helps!

This can't be that hard. I think I've enabled LDAP in Dovecot just by including dovecot-ldap.conf.ext in 10-auth.conf and using the default settings. I now have the configuration shown below. Two questions:
How do I set Outlook to authenticate with LDAP? Currently the Outlook accounts still have the ID and password set in "Logon Information". Checking "Require logon using Secure Password Authentication (SPA)" doesn't work. All I can seem to find on the Internet is how to configure address books using LDAP.
Should I remove "passdb { drive = shadow } from the dovecot configuration?

I've been using Dovecot 2.2.15 as the IMAP server for Outlook (2010/2013) on Windows workstations for over 6 months with no problems. Dovecot is hosted on the office Samba4 AC/DC server.
I have been using auth_mechanisms plain login, and passdb driver = shadow.
What I'd like to do now is use the "Windows Authenticated" login so I don't have to have separate passwords for users logging into the Windows AD workstations and their Outlook clients.
If anyone has actually done this I'd appreciate some tips. My various attempts have not been successful.
Here is my current config:
