i have a mail gateway appliance. it validate accounts on the iredmail with ldap source.
this feature also provides authentication remotely using ldap.
But i can not manage it. I get below error when i try to authenticate with postfix using my mailaddress and pass on it ;

It's clear here. Your gateway appliance is trying to connect to LDAP server with authentication (a.k.a. ldap bind). Please update your appliance setting to use a proper bind dn and password for authentication.

Re: how can i fix a ldap error

the SMG says "The wording "Could not create a validated object" is actually coming from your OpenLDAP server and the Messaging Gateway is just showing it to you.  You shoudl check your OpenLDAP server logs and troubleshoot from that end."

Re: how can i fix a ldap error

I'm afraid that i don't understand what you really want, but here's the bottom line:

The OpenLDAP service configured by iRedMail requires authentication to query it, connect anonymously is not allowed. So, if your mail gateway appliance needs to query OpenLDAP, please configure a bind dn and password for authentication.

iRedMail creates 3 bind DNs, they have different permissions:

* cn=Manager,dc=xx,dc=xx: this is LDAP root dn, it has all permissions to read and write LDAP server. It's just like system account root, or MySQL root account.
* cn=vmail,dc=xx,dc=xx: This dn has read-only permission.
* cn=vmailadmin,dc=xx,dc=xx: This dn has read and write permission to access o=domains,dc=xx,dc=xx and o=domainadmins,dc=xx,dc=xx.

Hope it helps.

Re: how can i fix a ldap error

I use cn=Manager,dc=xx,dc=xx on the appliance for full permission.  When i try to authenticate, I get an error on the SMG appliance ; "Failed to connect to LDAP server. Check the Control Center and DDS logs for details. DDS error code: 800400 Additional information returned by LDAP server: Failure connecting to data source: openldap Reason: Could not create a validated object"

the configuration and query on the smg appliance on the picture ;

Failed to connect to LDAP server.

Is the OpenLDAP service accessible from external network?

Re: how can i fix a ldap error

yes  it is accessible from outside and already the recipient validation checking works on it.

Re: how can i fix a ldap error

I have no idea ...

*) OpenLDAP is accessible from external network.
*) You have bind dn/password set in your appliance for authenticated ldap query.

What's the new error message and debug log in your appliance?

Re: how can i fix a ldap error

I'm afraid that I don't understand how your appliance uses LDAP bind/auth, i suggest you ask your vendor to get it working.
