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]
