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]
