UTM 9.508-10: Recipient varification with Active Directory still not working?

Franky83

Hi,

i have tried recipient verification with Active Directory, but that isn't working. I tried several ports (636, 389, 3268,3269) with Domain Controllers IP and FQDN, but i always get the following warning in the SMTP Live Log:

Warning: ACL "warn" statement skipped: condition test deferred: failed to bind the LDAP connection to server DOMAINCONTROLLERIP:636 - ldap_bind() returned -1

I can successfully test server connection and authenticate a user, but recipient verification is still not working. Any ideas?

Regards,

Frank

    Exchange Server must be the AD server to query i think. Primary DC doesnt have information for mailboxes

    This is not correct! Mailboxes are also linked with the user account in AD... This is also said in webadmin description for this feature.

     

    We use this feature already before 9.506 so it'sworking now. We'll not update to 9.508 at the moment...

    Hi,

    thanks for your replies. AD recipient verification was already failing before 9.508-10. I think it has something to do with SSL settings. My domain controller is using a self signed certificate, could it be a problem, that the UTM can't validate the certificate? I don't wan't to use LDAP instead of LDAPs. Do you know a logfile on the UTM which give me a little bit more informations?

    regards,

    Frank

    Just give it a short try, if it's working without encryption. This would give you the right direction for further steps. Some time ago UTM had problems with LDAPs.

    Best

    Wasn't this a bug (on more than one occasion) and you simply re-entered the details in again and it worked?

    On 9.508 for two days.  No problem with Recipient Verification in Active Directory.

    Cheers - Bob

    Just tested for the first time. No more emails for Group  "Disabled Users". I putted both AD Servers in Availability Group, just in case of Failure

    Maybe you have misconfigured the Server "Base DN:" that should match the group of users with mail addresses, Example:

    CN=Users,DC=COMPANY,DC=local 

     

     

    The same mus be in Recipient Verification

    Verify recipients:  In Acive Direcory

    Alternative Base DN: CN=Users,DC=COMPANY,DC=local

    Been on 9.508 since soft release, also have no problems, but run normal LDAP without LDAPS.

    Hi @ all,

    tanks for your replies.

    I have configured the Domain Controller to accept plain LDAP connections. Now recipient verification is working. If I switch back to LDAPS, recipient verification is not working. Any ideas why LDAPS is not working with recipient verification? User authentication is working with LDAPS.

    regards,

    Frank
