Exclude specific cakephp controller from http basic auth - apache

Question

I'm trying to exclude a path (URI) from being blocked by basic http auth.
The path is /rest (http://example.com/rest) and represents a controller of a cakephp 3 application. It is NOT a real file, but rather a path rewritten by a rewite-condition and handeled by index.php in the webroot dir.
Here's the rewrite rules:
/var/www/.htaccess:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^$ webroot/ [L]
RewriteRule (.*) webroot/$1 [L]
</IfModule>
/var/www/webroot/.htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
I'm running apache 2.4 and tried different configurations:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/webroot
<Directory /var/www>
Options FollowSymLinks
AllowOverride All
</Directory>
<Location "/">
AuthType Basic
AuthName "Keawe Development"
AuthUserFile /host/.htpasswd
Require valid-user
Require expr %{REQUEST_URI} =~ m#/rest/.*#
Require expr %{REQUEST_URI} =~ m#/index.php/rest/.*#
</Location>
ErrorLog ${APACHE_LOG_DIR}/error.log

... from HTTP Basic Auth Exclude Single File
However, none of them seem to work. I always get error 401 using wget or an auth request from a browser.
The problem seems to be, that the path /rest passes the condition but then is rewritten to index.php, which is under control of basic auth (and has to be).
Any clues?

Finally figured it out when I stumbelled upon this answer ( https://stackoverflow.com/a/14010456/1285585 ) to a related question.
Here is my solution:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/webroot
<Directory /var/www>
Options FollowSymLinks
AllowOverride All
</Directory>
<Location "/">
# Default to Basic Auth protection for any stie
AuthType Basic
AuthName "Keawe Development"
AuthUserFile /host/.htpasswd
Require valid-user
# If the request goes to a rest page: bypass basic auth
SetEnvIf Request_URI ^/rest/ noauth=1
Allow from env=REDIRECT_noauth
Allow from env=noauth
Order Deny,Allow
Satisfy any
Deny from all
</Location>
ErrorLog ${APACHE_LOG_DIR}/error.log
