php - LDAP 安全组 Symfony 2

Question

我努力让 LDAP 自定义身份验证在我的 Symfony2 项目上工作。我首先尝试使用 Fr3dLdapBundle 和其他软件，但它无法正常工作，而且它不支持安全组。

我终于可以使用这两个链接了:- https://groups.google.com/forum/#!topic/symfony2/RUyl15zaH8A- http://symfony.com/doc/current/cookbook/security/custom_authentication_provider.html

但是现在我必须检查某人何时登录，例如他是否在安全组“AdminMyWebsite”中。如果他是，我必须将他的角色设置为 ROLE_ADMIN。但我不知道该怎么做。

谁能帮我解决这个问题？

我解决了我的问题。我在 ldap_bind 之后添加了一个 ldap_search 来检查用户是否是安全组的成员

$ds = ldap_connect($this->server, $this->port);
        if ($ds) {
            try {
                if (ldap_bind($ds, $this->domaine . '\\' . $username, $password)){
                    $user = $this->m->getRepository('EspaceApprentiUserBundle:ApprenticeUser')->findOneBy(array('username' => $username));   
                    $filter = "(&(objectCategory=person)(samAccountName=" . $username . "))";
                    $result = ldap_search($ds, $this->dn, $filter);
                    $entries = ldap_get_entries($ds, $result);
                    if (in_array($this->administrator,$entries[0]['memberof']))
                    { 
                        $user->setRoles(array('ROLE_ADMIN'));
                        $this->m->persist($user);
                        $this->m->flush();
                    } else {
                        $user->setRoles(array('ROLE_USER'));
                        $this->m->persist($user);
                        $this->m->flush();
                    }       
                    return true;
                } else {
                    return false;
                }
            } catch (ContextErrorException $e) {
                $this->logger->error(' -- LdapProvider -> ldapBind() Unable to bind to server: Invalid credentials -- ' . $e->getMessage());
            }
        } else {
            $this->logger->info(' -- LdapProvider -> ldapBind() Unable to connect to LAPP Server -- ' . $this->server);
        }
