plack::middleware::auth::basic

Plack::Middleware::Auth::Basic(3pm)			User Contributed Perl Documentation		       Plack::Middleware::Auth::Basic(3pm)

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) = @_;
	     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 and password 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]
