Working setup with PHP 7.4 & 8.2 breaks with AuthType Basic

Thanks for the clear and easy-to-follow instructions on how to set up several PHP environments. All went fine, until I needed to add AuthType Basic to the virtual host. I wonder if you could help. Here’s the Apache2 conf:

<VirtualHost *:80>

        DocumentRoot /www/mytest/www-root
        <Directory />
                Options FollowSymLinks
                AllowOverride None

        <Directory /www/mytest/www-root/>
                Options Includes FollowSymLinks MultiViews
                Require all granted
                AllowOverride All

                <Limit GET POST OPTIONS PROPFIND>
                        Require all granted
                        Require all denied

        <Directory /www/mytest/www-root/>
          AuthName "MyTest Intranet"
          AuthType Basic
          Require expr %{REQUEST_URI} =~ m#^/.*#

          AuthBasicProvider dbd
          AuthDBDUserPWQuery "SELECT auth_passwd from authentication where auth_username = %s"
          Require dbd-group mytest_admin
          AuthzDBDQuery "SELECT groups FROM authentication WHERE auth_username = %s"

        <FilesMatch \.php$>
             # From the Apache version 2.4.10 and above, use the SetHandler to run PHP as a fastCGI process server
             SetHandler "proxy:unix:/run/php/php7.4-fpm.sock|fcgi://localhost"

        ErrorLog /var/log/apache2/www/

        # Possible values include: debug, info, notice, warn, error, crit,
        # alert, emerg.
        LogLevel debug

        CustomLog /var/log/apache2/www/ combined
        ServerSignature Off


If I remove the FilesMatch part, authentication works.

Accessing the site with Apache2 debug verbosity produces this:

As said, commenting the FilesMatch part, auth works and opens the page with log:

Any help would be highly appreciated.

The problem you’re facing seems to be related to the interaction between the AuthType Basic directive and the FilesMatch directive for PHP-FPM. Apache’s mod_proxy_fcgi doesn’t handle authentication headers properly. Hence, the PHP script being executed doesn’t have the necessary environment variables set to handle authentication.

One way to work around this is to use mod_rewrite in order to bypass the problem.

  1. Comment out or remove the <FilesMatch> section you currently have.

  2. Add the following block to the <Directory /www/mytest/www-root/> section in your Apache configuration:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} \.php$
RewriteRule (.*\.php)$ fcgi://{DOCUMENT_ROOT}/$1 [P,L]

Replace 9000 with the port PHP-FPM is listening on. If PHP-FPM is listening on a Unix socket, use the path to the socket file instead of

Remember, for this to work, the mod_rewrite module must be enabled. You can enable it with the command sudo a2enmod rewrite.

After making these changes, remember to restart Apache for the changes to take effect. This can typically be done with a command like sudo systemctl restart apache2.

This might solve the issue you’re facing.
