similar to: NTLM authentication with Outlook 2010

Dear Experts, I configured Samba, Kerberos, etc., can login to my CentOS using ADS account, but missing something in my Dovecot config. Windbind seems to work: [root at aCentOs2 dovecot]# wbinfo -a wAlex%pass plaintext password authentication succeeded challenge/response password authentication succeeded Same is true for ntlm_auth helper: [root at aCentOs2 dovecot]# /usr/bin/ntlm_auth

More on this ... I short-sheeted ntlm_auth to see what was being passed to it. It is getting as arg1: --helper-protocol=squid-2.5-ntlmssp I tried running ntlm_auth at the command line as: ntlm_auth --username=user --password=password --helper-protocol=squid-2.5-ntlmssp It did nothing, just hung there. The ntlm_auth man page says: --helper-protocol=PROTO Operate as a stdio-based helper.

Is it possible that no one on this list is authenticating Outlook with Dovecot and NTLM? --Mark -----Original Message----- Date: Fri, 08 Feb 2019 00:51:01 -0500 To: dovecot at dovecot.org Subject: Re: Need to authenticate Outlook and NTLM From: Mark Foley via dovecot <dovecot at dovecot.org> More on this ...

I've posted questions on this before, but now I really, really need a solution. Using Dovecot 2.2.33.2 We've been using Dovecot as IMAP server for several years on a Linux host which is also the Active Directory / Domain Controller. We have both Thunderbird and Outlook clients. The Thunderbird clients authenticate w/o problem with AD credentials using Kerberos/GSSAPI. I've never

I have been trying to get SSO to work correctly with the following packages, and I appear I am missing something and I was wondering if anyone can help me or point me in the right direction? I am currently using the "auth_ntlm_winbind_module" for apache to try and authenticate and was hoping to get SSO to work. I have gone through all the steps on SEVERAL sites trying to figure out how

Hi, though this is a bit of a side question, has anybody had an issue while running Outlook 2010 with Dovecot? The reason why I am asking is that I have setup a Dovecot 2.1.7 server on FreeBSD which works fantastically with Thunderbird but Outlook seems to be twice as slow in transferring information across?? # dovecot -n # 2.1.7: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-RELEASE

Also it seems we lack support for NTLMv2. If you want to use NTLM you need to permit use of NTLM(v1), which is usually not enabled by default.

You are aware, I hope, that NTLM v1 is well over 20 years old and is trivially compromised today. Basically, it's about as secure as sending plaintext passwords. Since you're supporting SSL on your Dovecot server, why not

I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times) disconnect in IDLE and inactivity time outs. I'm using only IMAP with two users. Both users access the server from multiple devices, phone, tablet and desktop computer. I had previously set the max_userip_connections to 20 and rarely got the

Hi!, I'm trying to use single sign on from Windows. Install dovecot on CentOS 6. The host name is prueba-mail. I'm using version 2.0.9 because the latest 64-bit gives errors. But first I wanted to test whether user validation works with telnet. When I try to try "telnet prueba-mail imap" and try to "a1 LOGIN MyUsername MyPassword", I get the following error:prueba-mail

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.

Hello my goal is to write an authentication module for the Symfony php framework, which would provide SSO capabilities to browsers that are logged in an MS AD domain and support the NTLMv2 protocol. Ideally this module would run on linux servers, and be portable, i.e. require as few non-php tools and network/firewall settings as possible (that's why I eschewed the existing Apache modules

Hi all, I have a running Samba4 Server. I am able to authenticate Windows and Linux Clients very. (1) I want to use samba4 as SSO. In this regard my next step is to authenticate our web site users from samba4 server. In this web site, at home page our corporate users give their e-mail address username at companydomain.com and password (not e-mail password). (2) Our E-mail server is hosted on

Hmmm, really? And yet

Now that I am running Thunderbird on Linux and away from Windows/Outlook, I'd like to take another run at setting up NTLM authentication from Thunderbird to my Samba4 AC/DC. With the help of the samba maillist folks I was able to set up NTLM authentication for domain user login. I should be able to do the same for email! But, I need help. I went to
