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! Rick Quoting Mark Foley <mfoley at ohprs.org>:> This can't be that hard.

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.

The failed ntlm look-up is looking up user mark at 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.

Subject: Re: How to "Windows Authenticate"
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.
