I'm following the instruction on Acquia's site https://docs.acquia.com/articles/using-simplesamlphp-acquia-cloud-site about configuring SimpleSAMLphp and it just seems the documentation is not very precise. In their documentation it says to run the following command to install SimpleSAMLphp library.

cd docroot; ln -s ../simplesamlphp/www simplesaml

And to install the Install the simplesamlphp_auth Drupal module, they linked to the simpleSAMLphp Authentication page, https://www.drupal.org/project/simplesamlphp_auth. And in the SimpleSAMLphp Installation, it's linked to the SimpleSAMLphp Installation and Configuration page, https://simplesamlphp.org/docs/stable/simplesamlphp-install. However, the instruction in this page looks just like what I've done in the second step of Acquia's documentation. Instead of extract the simplesamlphp-1.x.y alongside the docroot, it suggest to extract it inside the var folder.

Now, once I've gone through the instruction on Acquia's documentation and tried to access the simplesaml, https://mywebsite.dd:8443/simplesaml/, I got the following error:

Forbidden You don't have permission to access /simplesaml/ on this server.

So I found this thread, Getting a 403 forbidden error for simplesaml after Apache upgrade, that talks about the error which looks like step 6 in the SimpleSAMLphp Installation and Configuration instruction. So I went to the /Applications/DevDesktop/apache/conf/extra/httpd-vhosts.conf and configured the following:

<VirtualHost *:8083>
     ServerAdmin userName@mywebsite.com
     DocumentRoot "/Users/userName/sites/drupalsites/docroot"
     ServerName drupalsites.local
     ServerAlias drupalsites.local
     ErrorLog "logs/drupalsites-error_log"
     CustomLog "logs/drupalsites-access_log" common
     <Directory "/Users/userName/sites/drupalsites/docroot">
         Options Indexes FollowSymLinks Includes ExecCGI
         AllowOverride All
         Require all granted
     </Directory>

     Alias /simplesaml simplesamlphp/www

    <Directory "/Users/userName/sites/drupalsites/simplesamlphp/www">
         Require all granted
     </Directory>

 </VirtualHost>

However, I'm still getting the same error.

Forbidden

You don't have permission to access /simplesaml/ on this server.

So, the questions are, did I go about installing SimpleSAMLphp the wrong way? Second, if not, where did I go wrong? Third, how do I resolve this error and back on track again? I have also found this documentation, https://www.chapterthree.com/blog/how-to-configure-simplesamlphp-for-drupal-8-on-acquia, that talks about setting up SimpleSAMLphp on Aquia's plaform but it's not very consistent with other documentations I've listed above. So, I'm not sure which I should follow. Any suggestion is much appreciated.

try adding this to your docroot/.htaccess 

RewriteCond %{REQUEST_URI} !^/simplesaml

To be more precise with @realgt answer :

  # Copy and adapt this rule to directly execute PHP files in contributed or
  # custom modules or to run another PHP application in the same directory.
  RewriteCond %{REQUEST_URI} !/core/modules/statistics/statistics.php$
+ # Allow access to simplesaml paths
+ RewriteCond %{REQUEST_URI} !^/simplesaml
  # Deny access to any other PHP files that do not match the rules above.
  RewriteRule "^.+/.*\.php$" - [F]
