LDAP_add with PHP: operation error

I am using LDAP (this is actually my first project) and I can’t find a google answer that can help me ... Therefore my problem: I am trying to add a contact with php to the active directory on a Windows 2003 server. I can connect to the server, and I have no problem with ldap_bind. But when I run the program, I always get an error message:

Warning: ldap_add () [function.ldap-add]: Add: Operational error in (Blabla) in bla string

and ldap_error also says only “Operation Error”, which is rather vague, so I don’t even know if there is a problem with the server or with my code. I saw some threads with similar problems when the servers did not allow anonymous access, but I even contact the administrator account and still does not work.

My code looks something like this:

$ldapcon=ldap_connect("servername");

if($ldapcon) {
    $bind=ldap_bind($ldapcon,"Admin@domain.com", "somePassword");
    if($bind) {         
        //  create data...
        $info=array();
        $info["cn"][0]          = "Hans Mustermann";
        $info["sn"][0]          = "Mustermann";
        $info["givenName"][0]   = "Hans";
        $info["mail"][0]        = "MustermannH@firma.de";
        $info["objectclass"][0] = "top";
        $info["objectclass"][1] = "person";
        $info["objectclass"][2] = "organizationalPerson";
        $info["objectclass"][3] = "contact";
        $info["ou"][0]          = "Users";
        $info["ou"][1]          = "contact";

        // add Data...
        $r=ldap_add($ldapcon, "cn=Hans Mustermann, sn=Mustermann", $info)
            or die(ldap_error($ldapcon)); //error: operations error
    }
}

Is there any information? Is the code incorrect? Do I need some changes to my ad settings? is it a problem with "setting up remote rights" or something else? Am I just too stupid and blind to see the problem, or is this a big thing that is not easy to fix? Do any of you have an idea?

Thanks a lot Chillikarli

Instead of the or die () condition, you can try this

// add Data...
if(!(ldap_add($ldapcon, "cn=Hans Mustermann, sn=Mustermann", $info))) {
     echo "There is a problem to create the account\n";
     echo "Please contact your administrator !\n";
     echo "LDAP Error: ".ldap_error($ldapcon)."\n";
     exit;
}
ldap_unbind($ldapcon);
