Web access authentication setup

1. Create user passwd file: "htpasswd -c /etc/httpd/userfile username"; if "-c" flag is included, existing file will be overwritten, so no need for it when adding extra users.
   
2. Insert directive in httpd.conf file:
• 
  
• AuthName "Restricted Area"
• AuthType Basic
• AuthUserFile /etc/httpd/users
• require valid-user
