Specific folder access rules for specific users with .htaccess

Question

With the settings below, both user-1 and user-2 can access to site-1 and site-2 after login. However, I want to change access rights as listed below:

• user-1 can access only site-1 ( http://test.local/site-1 )
• user-2 can access only site-2 ( http://test.local/site-2 )

How can I do it?

Site structure

test
   site-1
      index.php
   site-2
      index.php
   index.php
   .htaccess
   .htpasswd

.htaccess

AuthType Basic
AuthName "Protected Test Site"
AuthUserFile /var/www/html/local/test/.htpasswd
Require valid-user

.htpasswd

user-1:$apr1$CraA.0n7$JRqS7GyggMKNYcTP65rAW/
user-2:$apr1$NbKoZeyJ$P33C/1ceg1XGfLaPsWBgW1

test.local.conf

<VirtualHost *:80>
        ServerName test.local

        DocumentRoot /var/www/html/local/test

        <Directory /var/www/html/local/test>
                AllowOverride AuthConfig
                Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
                Order allow,deny
                Allow from all
        </Directory>
</VirtualHost>

Answer 1

Either change:

Require valid-user

to:

Require user user-1

alternatively create yourself two group files, and change the line to something along the following lines:

Require group siteOneUsers

see: http://httpd.apache.org/docs/2.2/mod/core.html#require

Answer 2

Along with what I did above in OP, I solved the problem with creating additional .htaccess files right inside site-1 and site-2 so the contents are:

site-1/.htaccess

AuthUserFile /var/www/html/local/test/.htpasswd
Require user user-1

site-2/.htaccess

AuthUserFile /var/www/html/local/test/.htpasswd
Require user user-2
