What are some common LDAP errors that PHP developers encounter when trying to add entries to an LDAP server?

One common LDAP error that PHP developers encounter when trying to add entries to an LDAP server is the "LDAP error code 32 - No such object." This error typically occurs when the base DN specified in the LDAP query does not exist in the LDAP server. To solve this issue, you need to ensure that the base DN is correct and that it exists in the LDAP server.

// Specify the correct base DN for the LDAP server
$base_dn = "dc=example,dc=com";

// Add the entry to the LDAP server
$ldap_entry = [
    "cn" => "John Doe",
    "sn" => "Doe",
    "mail" => "john.doe@example.com"
];

$ldap_add = ldap_add($ldap_connection, "cn=John Doe," . $base_dn, $ldap_entry);

if (!$ldap_add) {
    $ldap_error = ldap_error($ldap_connection);
    echo "Error adding LDAP entry: " . $ldap_error;
}
