I'm OK with continuing to try gssapi, esp. if NTLM is restricted to v1. I do have the Dovecot sources and will peruse the possible options after I send this. I am on version 2.2.15 and I see that the current downloadable

The last log line shows "user=<>". This indicates no credentials were presented. If the rip field matches the client ip you tested from, I would bet the appropriate kerberos ticket (imap/host.domain.tld at REALM) was not pulled for the authentication.

Hi Mark, Just to let you know that we are running dovecot with AD. (and I guess: *many* people are running that combination) It worked without issues, we are using in dovecot-ldap.conf.ext: > auth_bind = yes this user/passwd filter: > = (&(objectclass=person)(sAMAccountName=%n)(!(userAccountControl=514))) > dn = cn=search_dovecit,cn=users,dc=company,dc=com > dnpass =

Did a few test here "auth_gssapi_hostname = "$ALL"" is no longer required with dovecot (2.2.13 here). Add "auth_debug=yes" to your dovecor config. 192.168.100.1 is my clients ip 192.168.100.101 is the servers ag is the domain account username I use to login to windows and also the username configured in thunderbird. On my debian system an package named

More info ... when I do MAIL=imap://mark at mail.ohprs.org/ mutt (using the domain of the registered certificate). I do not get the message "Certificate host check failed: certificate owner does not match hosthame ..." I do get the same (mutt?) edit screen shown below with the "(r)eject, accept (o)nce, (a)ccept always" action at the bottom. If I "accept (o)nce",

About a year-and-a-half ago I wrote in a thread having this same subject about a problem my sendmail server was having on my Samba4 AD/DC. To solve that problem at the time, I maintained domain user entries in both the sam.ldb and in /etc/passwd, and did not have winbind specified in /etc/nsswitch.conf. I am now trying to remove all users from /etc/passwd and use winbind. Unfortunately, I'm

It should work. Although if you are using linux server you might want to use gssapi instead. > On June 25, 2016 at 7:43 PM Mark Foley <mfoley at ohprs.org> wrote: > > > I've asked this several times over the past year with essentially zero responses.

Unfortunately, I tried for weeks to figure out passdb ldap without success. I guess I'm just not knowledgeable enough about how to use ldap and Active Directory. The dovecot wiki https://wiki2.dovecot.org/AuthDatabase/LDAPm doesn't help me much. All it says is: Active Directory When connecting to AD, you may need to use port 3268. Then again, not all LDAP fields are available in port

Debug log output please! I think you still miss the gssapi module for dovecot. Am 03.07.2016 um 19:42 schrieb Mark Foley: > Achim, > > This is my most recent effort.

You might get better results with https://wiki.dovecot.org/HowTo/ActiveDirectoryNtlm It seems you'd have to configure OpenLDAP backend for Samba to have LDAP.

Hi Mark, I've had the same trouble with the DOMAIN\user on my DCs, and as Rowland has already pointed out, the "winbind use default domain = yes" configure option is not honored on a DC. My guess is that is because a Samba DC can only be a DC for one domain, so that is why it isn't honored. If I do "getent passwd username" on my DCs, they all return

mj - thanks! That the first useful example I've received from any forum/list. I'm getting ready to try my config (have to do so after hours), but I have some probably simple-minded questions: Your example is not the complete dovecot-ldap.conf.ext file, right? Have you just given me differences in your config from the "original"? You've kept the hosts, base, ldap_version,
