My dovecot works fine against Active Directory 2003, but not against AD2008
Hello,
my dovecot installation has been working fine against AD till we upgrade from AD 2003 to AD 2008. As http://wiki2.dovecot.org/AuthDatabase/LDAP said, now I'm not able to connect AD through 389 port. The port 3268 works fine though.

Is there a technical reason for this problem? Does it exist any workaround?
The use of Global Catalog (port 3268) is not a solution for me, since it misses many attributes. (ex. I use the field "initials" to set the quota and this field is not available through port 3268).
I also noticed that, now, it uses any DC available in the domain, it doesn't care what I configured in "hosts = " parameter.
This is using "hosts = dc03.domain:389":
[root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth
tcp 22 0 <dovecotServer_IP>:55217
<dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth
tcp 22 0 <dovecotServer_IP>:57645
<dc06.domain_IP>:389 ESTABLISHED 4872/dovecot/auth
tcp 0 0 <dovecotServer_IP>:55216
<dc03.domain_IP>:389 ESTABLISHED 4872/dovecot/auth
It looks like it does a look up for other domains controller (I don't know how nor why) and it connect aleatory to any DC in my domain (in this case dc06.domain, but it changes any time), additionally to the configured one (dc03.domain).
This is using "hosts = dc03.domain:3268":
[root@<dovecotServer> ~]# netstat -anp | grep dovecot | grep auth
tcp 0 0 <dovecotServer_IP>:58485
<dc03.domain_IP>:3268 ESTABLISHED 4982/dovecot/auth
In this case, only the configured server in host parameter is used (I think this is the right behaviour)

I've logged a session using the option debug_level = -1.
The log is attached.
I still don't understand what is happening and why all my domain controllers are being used even when I just use one of them in "host" parameter in my /etc/dovecot/dovecot-ldap.conf.ext.
Thanks in advance, Regards

for
REFERRALS off
I had this errors with "referrals on" in misconfigured dns environments.
you can debug the dns packets by strace-ing the auth process

Fran and/or Matthias,
Could you publish your doveconf -n? I can't get dovecot to authenticate with my AD. Maybe you have a solution I could try.
What mail client(s) are you using? I assume by "AD 2003/8" You mean SBS2003/8 and are therefore using Outlook?

Hi Mark,
when I say AD 2003/8 I mean Active Directory 2003/8.
My configuration is attached.
I based my installation (dovecot+postfix) in the guides of this site: http://www.linuxmail.info
The LDAP part is this: http://www.linuxmail.info/postfix-dovecot-ldap-centos-5/
You can also use PAM to connect to AD (http://www.linuxmail.info/active-directory-dovecot-pam-authentication/) but that way doesn't allow to retrieve custom fields from the AD (ex. a field to set quota per user), so I'm using the standard LDAP method.
Regards

Hi Matthias,
thank you very much! that fixed the problem.
I had workaround the problem by using "base = ou=xxxx, dc=dom", instead of "base = dc=dom" in the dovecot-ldap.conf.ext file, because that also worked (I don't know why, but the problem happen if you use as base just the domain, but not if you add a second level). But that forced to me to use several userdb/passdb blocks definitions, one for each OU in which I have users, so I think that your fix is better.
I'm not able to understand the actual reason behind all this though...
What's the technical explanation behind this behaviour?? I mean, it seems to be that the problem is that the Domain controller (DC) was sending a "referrals" answer and dovecot auth made a connection to these others DC but something wrong happened (dovecot can't deal correctly with that kind of answers?? I don't know).
Anyways, as far as I know:
- A referral answer should be done by a DC when it can't provide the object that the client are requesting
- REFERRALS off in ldap.conf means that the client should not follow referrals returned by the DC
So, if a referral answer is given from my DC, I think that is because such DC can't provide the object which the client is looking for, so, why works fine just by telling dovecot: "Don't follow referrals"?

Hi Fran,
this is not a dovecot problem, thats a pure dns problem and can only be fixed in your dns environment.
referrals are propagated in a "special" dns design in SRV records. so the ldap client performs a dns lookup for this names and this is the point of hanging (as in most "hanging cases", its dns).
