Configuration of dovecot 2.0.19 to authenticate users via LDAP
I am trying to get dovecot 2.0.19 authenticate users via LDAP (OpenLDAP
2.4.28) and using Wireshark to debug the process. It looks like the basic
configuration of dovecot is fine, but it doesn't pull it off to send the
right request to the LDAP server. First of all, this is how my LDAP-entries
look:
# ht

objectClass: top

Hi list
Does anyone has experience in setting up dovecot or any other mail
system with user auth against a Samba4 AD ? If yes could I get some
advice on that Topic or even a link to a ressource where I can get some
Information. Googled a lot but didn't find something yet.
Thankx in advance.

Dovecot not surviving OpenLDAP restart
Hi!
Running Dovecot 2.2.36 and authenticating against
an OpenLDAP 2.4.45 server.
Now since some update of dovecot it will not be able to authenticate
your logins after a restart of the LDAP service is restarted
without a reboot of the dovecot server.
Anything new here that I should be aware of?
Best Regards

Hi All
I am using Dovecot dovecot2-2.2.25_6 on FreeBSD 11. I am trying to set up

Dovecot 2 LDAP "unknown user"
Thanks for your reply again Steffen.
The command doveadm user -u username successfully returns the username and
any information it can for the user in AD. As a matter of fact, I entered
some home directory information in AD and this command returned the User's
Home Directory as well. Is it a problem though that the telnet test won't
work?

Configuring Dovecot for use with Active Directory
Hello,
My server is configured as follows:
FreeBSD 6.1
OpenLDAP 2.3.27
Cyrus SASL 2.1.21
Dovecot 1.0.rc15
I have PostFix configured to use SASL for SMTP AUTH, which in turn leverages OpenLDAP to verify users in Active Directory. I do not have, nor want to in the future, local users in FreeBSD, so I've configured PostFix for Virtual Mailboxes.
Everything is working and I'm getting

dovecot imap hangs
All,
I recently did a fresh install/setup on centos 5 to replace my older
courier-imap and all seemed to go well until today I started to notice
that it simply hangs. I use thunderbird and squirrel mail and after a
while it seems like I"m simply rejected. I'm almost guessing that it has
to do with the session timing out and then dovecot is unwilling or
unable to renew the session. I

"Temporary authentication failure" ? Cant connect with ldap user
@Steffen Kaiser:
Sorry I wrote that wrong. I did indeed *grep -v '^ *\(#.*\)\?$'
dovecot-ldap.conf.ext* to get those results.
@Bob Miller:
And how would that look like? I added a auth_bind_userdn looking like this:
*auth_bind_userdn = uid=%u,dc=[hostname],o=de*
And restartet dovecot, no use.
Any other ideas?
Best,

Hello Samba group,
I ran into a problem concerning Dovecot LDAP authentication to the Samba4 Active Directory.
