Password Protected directories goes to 404 Error Page on a Drupal site

[Alec:D]

After protecting directory from Cpanel >> Security >> Password Protect Directories

password protected Directory were showing 404 page not found error page by Drupal. Drupal sometimes goes crazy and produces weird problems.

Resolution :
Add the following code in .htaccess file which located under protected directory.

[root@sever~]# cat .htaccess

AuthName "Restricted Area"
AuthType Basic
AuthUserFile /home/user/public_html/cgi-bin/testdir/.htpasswd
AuthGroupFile /dev/null
require valid-user

ErrorDocument 401 401.html

Restarted the httpd service it required.

Problem should be solved now.

Done...
