Apache 2.4 reverse proxy setup cannot impose basic authentication - apache

Question

I have apache2.4 set up and when visiting any apache served web sites basic authentication works great.
Now I have one more webserver running from an other service at port 8000 and I wanted to setup apache as a reverse proxy hoping that it can also impose and handle basic authentication there as well...but instead for asking for user and password it just serves the website unprotected.
my setup is:
<VirtualHost *:8000>
ProxyPreserveHost On
ProxyPass / http://192.168.0.101:8000/
ProxyPassReverse / http://192.168.0.101:8000/
<Location />
AuthType Basic
AuthName "Authorization"
AuthUserFile /etc/htpasswd/.htpasswd
require valid-user
</Location>
</VirtualHost>
what am i doing wrong?
Update:
solution found by marked answer:
<VirtualHost *:8000>
ProxyPreserveHost On
<Location />
ProxyPass http://192.168.0.101:8000/
ProxyPassReverse http://192.168.0.101:8000/
AuthType Basic
AuthName "Authorization"
AuthUserFile /etc/htpasswd/.htpasswd
require valid-user
</Location>
</VirtualHost>
Also make sure that apache is configured to listen to that port and also if the proxied server is local it is not running at the same port as listened one

Answer 1

The problem is that Apache doesn't 'link' Proxypass / http://example.com and <Location /> - even though they both try to work with /. This means that Proxypass is handling requests for '/' first, and the Location section is never being used.
You need to move the Proxy config inside the Location, dropping the path, e.g.:
<VirtualHost *:8000>
ProxyPreserveHost On
<Location />
ProxyPass http://192.168.0.101:8000/
ProxyPassReverse http://192.168.0.101:8000/
AuthType Basic
AuthName "Authorization"
AuthUserFile /etc/htpasswd/.htpasswd
require valid-user
</Location>
</VirtualHost>
