Topic: Integration samba4 Dovecot can't login

Hello!

I'm trying to setup iredmail e-mail server and integrate it with Samba 4 domain controller.
So far, so good using this manual: http://www.iredmail.org/wiki/index.php? … y.iRedMail
First of all could not make dovecot start, because of vmail group was missing. So created a group called vmail (groupadd -g 5000 vmail).
I'm getting to the point where i should telnet to localhost on 143 port, but all the time i get an error message "* BYE Internal error occurred. Refer to server log for more information."
Have no idea where to look for some ideas sad

root@mail:/# ls -lan /var/vmail/vmail1/
total 8
drwxr-x--- 2 10000 5000 4096 dec  7 12:01 .
drwx------ 5     0    0 4096 dec  7 12:02 ..

Here's my setup and tail of dovecot.log

==== Required information ====
- iRedMail version: 0.8.3
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): LDAP
- Linux/BSD distribution name and version: Ubuntu 12.04.1

Port 143 is not enabled by default, please use port 993 (IMAP over TLS) instead.

Directory /var/vmail must be owned by "vmail:vmail", permission 0700.

Thanks for your reply!
Permissions are:
root@mail:/var/vmail# ls -l
total 12
drwx------ 2 vmail vmail 4096 dec  7 12:02 backup
drwx------ 2 vmail vmail 4096 dec  7 12:02 sieve
drwx------ 2 vmail vmail 4096 dec  7 12:01 vmail1

Tryed too use port 993, but no success sad
dovecot .log says:
Dec 09 10:32:25 imap-login: Info: Disconnected (no auth attempts): rip=127.0.0.1, lip=127.0.0.1, TLS handshaking: SSL_accept() failed: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

Looking in dovecot.conf and can't find out should these lines has to look like this:
auth_default_realm =

# Authentication mechanisms.
auth_mechanisms = PLAIN LOGIN

Re: Integration samba4 Dovecot can't login

Try to enable insecure IMAP connection by following this tutorial, then try again with port 143:
http://www.iredmail.org/wiki/index.php? … t.STARTTLS

But what does it mean to the mail system with enabled plain text auth?!

Need assistance sad
I can log in to webmail using Samba 4 users, but the problem is with trying to send an email message:
1) auto-complete of To: doesnt work: - "Dec 10 21:51:42 mail roundcube: PHP Error: Addressbook source (ldap_global) not found! in /usr/share/apache2/roundcubemail-0.8.2/program/include/rcmail.php on line 463 (POST /mail/?_task=mail&_action=autocomplete?_task=&_action=)"

Any ideas where to look for?

You didn't define global ldap address book "ldap_global" in Roundcube config file.

Either create user "vmail@" or create an alias (in /etc/postfix/aliases) for vmail.

There is an alias already in aliases - vmail: root

In /usr/share/apache2/roundcubemail/config/main.inc.php i have:
$rcmail_config['ldap_public']["example.com"] = array(
    'name'          => 'Global Address Book',
etc.
Still the same error messages! sad

Re: Integration samba4 Dovecot can't login

Well, it's ldap_public, not ldap_global.

But have no idea what to do with this postfix error sad

"invalid credentials" always means incorrect bind dn or bind password. So please check them in your Roundcube config file. If you aren't quite sure what the root cause is, show us your address book related settings here to help troubleshoot.

Address book related part looks like this!

Dear snpz,

This bind_dn format is default one used in iRedMail + OpenLDAP. Do you have the same structure in Active Directory? I'm afraid not.
So, please modify it to fit your Active Directory structure, or, follow our wiki tutorial to use a global bind dn instead.
http://www.iredmail.org/wiki/index.php? … be_webmail

P.S. If there's a tutorial, please follow it strictly first. if it doesn't work for you, then tune it.
Many users reported this or that issue, all are caused by not following our wiki tutorial STRICTLY. Don't make me feel i'm wasting time to write detailed wiki tutorials.
