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)
