NAME

       Plack::Middleware::Auth::Basic - Simple basic authentication middleware

SYNOPSIS

         use Plack::Builder;
         my $app = sub { ... };

         builder {
             enable "Auth::Basic", authenticator => \&authen_cb;
             $app;
         };

         sub authen_cb {
             my($username, $password, $env) = @_;
             return $username eq 'admin' && $password eq 's3cr3t';
         }

DESCRIPTION

       Plack::Middleware::Auth::Basic is a basic authentication handler for Plack.

CONFIGURATION

       authenticator
           A callback function that takes username, password and PSGI environment supplied and returns whether
           the authentication succeeds. Required.

           Authenticator can also be an object that responds to "authenticate" method that takes username and
           password and returns boolean, so backends for Authen::Simple is perfect to use:

             use Authen::Simple::LDAP;
             enable "Auth::Basic", authenticator => Authen::Simple::LDAP->new(...);

       realm
           Realm name to display in the basic authentication dialog. Defaults to restricted area.

LIMITATIONS

       This middleware expects that the application has a full access to the headers sent by clients in PSGI
       environment. That is normally the case with standalone Perl PSGI web servers such as Starman or
       HTTP::Server::Simple::PSGI.

       However, in a web server configuration where you can't achieve this (i.e. using your application via
       Apache's mod_cgi), this middleware does not work since your application can't know the value of
       "Authorization:" header.

       If you use Apache as a web server and CGI to run your PSGI application, you can either a) compile Apache
       with "-DSECURITY_HOLE_PASS_AUTHORIZATION" option, or b) use mod_rewrite to pass the Authorization header
       to the application with the rewrite rule like following.

         RewriteEngine on
         RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
