Apache LDAP/AD разрешает аутентификацию из нежелательных групп безопасности?

Я использую обратный прокси-сервер Apache (v2.4.18) для аутентификации пользователей по Active Directory (AD) моего учреждения для доступа к ряду блестящих веб-приложений (App1, App2 и т. Д.). Чтобы опубликовать новое приложение, мне нужно создать каталог для нового приложения в /srv/shiny-server/, например:

/srv/shiny-server/App1

Затем я иду в файл Apache Conf в /etc/apache2/sites-enabled/000-default.conf и добавьте следующий фрагмент для каждого приложения:

        # controls permission access to https://example.com/App1
        <Location /App1>
            AuthBasicProvider ldap
            AuthType Basic
            AuthName "insert credentials to login"
            AuthLDAPURL ldap://myldap/DC=X1,DC=com,DC=XX?sAMAccountName?sub?(objectClass=User)

            AuthLDAPBindDN "CN=svc_ldap,OU=XX1,OU=XX2,DC=X1,DC=com,DC=XX"
            AuthLDAPBindPassword my.pass

            AuthLDAPGroupAttributeIsDN on
            Require ldap-group CN=SGG_App1,OU=XXX1,OU=XXX2,OU=XXX3,OU=XXX4,DC=X1,DC=com,DC=XX  
            AuthUserFile /dev/null
        </Location>

Когда я унаследовал проект от коллеги, которого больше нет в моей организации, мы использовали три приложения: App1, App2 и App3. Каждый из них может быть доступен пользователям в определенной группе безопасности: SGG_App1, SGG_App2 и SGG_App3. Эти SG существуют в надлежащем месте на сервере LDAP, и пользователи в одной группе не могут получить доступ к приложениям из других групп. All users have access to the index.html in location ' / ' (https://www.example.com).

I recently needed to publish a fourth app (App4) which only users in SGG_App1 should be able to access. I followed the above steps, but even though I set the following in the .conf file, all users can access the new app, even those in other SGs:

Require ldap-group CN=SGG_App1,OU=XXX1,OU=XXX2,OU=XXX3,OU=XXX4,DC=X1,DC=com,DC=XX

It seems as if the new app was inheriting its permissions from somewhere else, as if what I put in the configuration file does not matter. I am evidently not an expert in Apache, but have navigated many tutorials and forums but do not seem to find the answer, so even a push in the right direction would be appreciated.

Just in case I am missing something in the configuration file that could give someone a clue of what I am doing wrong, I copy it below:

Listen *:80

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        # probe site https://example.com/probe required for application gateway to work
