A Sample LDAP Application in PHP Page 21

We collect the attributes of the new entry to be added in an associative array:

        $entryToAdd["cn"] = $cn;
        $entryToAdd["sn"] = $sn;
        $entryToAdd["mail"] = $mail;
        $entryToAdd["employeenumber"] = $employeenumber;
        $entryToAdd["ou"] = $ou;
        $entryToAdd["telephonenumber"] = $telephonenumber;
        $entryToAdd["objectclass"] = "person";
        $entryToAdd["objectclass"] = "organizationalPerson";
        $entryToAdd["objectclass"] = "inetOrgPerson";

Here we construct the DN corresponding to the new entry:

        $dnString = "mail=" . $mail . "," . "ou=". $ou . "," . $baseDN;

This is the root DN we shall bind to, before performing the add operation:

        $adminRDN = "cn=Admin," . $baseDN;

We connect to the server and bind as an administrator:

        $linkIdentifier = connectBindServer($adminRDN, $adminpassword);
        if ($linkIdentifier) {

The actual addition is done here:

            if (ldap_add($linkIdentifier, $dnString,
			 $entryToAdd) == true) {
                generateHTMLHeader("The entry was added succesfully");
                returnToMain();
            } else {
                displayErrMsg("Addition to directory failed ! !");
                closeConnection($linkIdentifier);
                returnToMain();
                exit;
            }
        } else {
            displayErrMsg("Connection to LDAP server failed!");
            exit;
        }
    }
}
?>

A typical screen prompting the user to enter the attributes would like below:

We need to be aware of certain caveats with this application that arise from the fact that this is merely illustrative of the PHP LDAP API and not a fully-fledged production application. As mentioned before the use of HTTP sessions is highly recommended to indicate authentication status. Further users created using the add mechanism do not have a password field due to which modification of such entries is not possible through the current mechanism.
