Hmm. I would expect to see 'mark@hprs.com'. Whatever your full domain name is.
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. 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.
I assume /etc/nsswitch.conf has been modified to use Samba?
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...

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?
Anybody?

I have been using auth_mechanisms plain login, and passdb driver = shadow.
