Apache 2.4：要求（例如全部被拒绝）指令未得到遵守

我在 Ubuntu 20.04 上运行 Apache 2.4.41 并且无法在我的 VirtualHost 上获得任何 Require 指令。作为一个最低限度的工作示例，我的 VHost 文件：

<VirtualHost *:80>
        ServerName my.domain.com
        DocumentRoot "/var/www/html/admin"

        <Directory /var/www/html/admin>
               Require all denied
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

旨在阻止所有访问，但日志显示：

[authz_core:debug] [pid 340724] mod_authz_core.c(735): [client ***.***.***.***:59008] AH01625: authorization result of <RequireAny>: granted (directive limited to other methods)

我在 Apache 配置树的其他地方看不到任何对 Require 行为的覆盖。例如，/etc/apache2/apache.conf包含：

<Directory />
        Options FollowSymLinks
        AllowOverride None
        Require all denied
</Directory>

<Directory /usr/share>
        AllowOverride None
        Require all granted
</Directory>

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
</Directory>

我加载的模块是：

 reqtimeout_module (shared)
 rewrite_module (shared)
 setenvif_module (shared)

apachectl -t并apachectl -S给出标准输出。

有人对我接下来应该去哪里有任何想法吗？

（提醒：Apache 2.4 不是 Apache 2.2 所以希望使用当前的术语）
