433 | =head1 DESCRIPTION |
434 | |
513d8ab6 |
435 | This module lets you use HTTP authentication with |
d99b7693 |
436 | L<Catalyst::Plugin::Authentication>. Both basic and digest authentication |
437 | are currently supported. |
438 | |
439 | When authentication is required, this module sets a status of 401, and |
440 | the body of the response to 'Authorization required.'. To override |
441 | this and set your own content, check for the C<< $c->res->status == |
442 | 401 >> in your C<end> action, and change the body accordingly. |
443 | |

445 | |
446 | =over 4 |
447 | |
448 | =item Nonce |
449 | |
450 | A nonce is a one-time value sent with each digest authentication |
451 | request header. The value must always be unique, so per default the |
452 | last value of the nonce is kept using L<Catalyst::Plugin::Cache>. To |
453 | change this behaviour, override the |
454 | C<store_digest_authorization_nonce> and |
455 | C<get_digest_authorization_nonce> methods as shown below. |

459 | =head1 METHODS |
460 | |
461 | =over 4 |
462 | |
513d8ab6 |
463 | =item new $config, $c, $realm |
d99b7693 |
464 | |
513d8ab6 |
465 | Simple constructor. |
d99b7693 |
466 | |
41091cd6 |
467 | =item init |
468 | |
469 | Validates that $config is ok. |
470 | |
513d8ab6 |
471 | =item authenticate $c, $realm, \%auth_info |
d99b7693 |
472 | |
513d8ab6 |
473 | Tries to authenticate the user, and if that fails calls |
474 | C<authorization_required_response> and detaches the current action call stack. |
d99b7693 |
475 | |
476 | Looks inside C<< $c->request->headers >> and processes the digest and basic |
477 | (badly named) authorization header. |
478 | |
479 | This will only try the methods set in the configuration. First digest, then basic. |
480 | |
bf399285 |
481 | The %auth_info hash can contain a number of keys which control the authentication behaviour: |
482 | |
483 | =over |
484 | |
485 | =item realm |
486 | |
487 | Sets the HTTP authentication realm presented to the client. Note this does not alter the |
488 | Catalyst::Authentication::Realm object used for the authentication. |
489 | |
05512a69 |
490 | =item domain |
bf399285 |
491 | |
05512a69 |
492 | Array reference to domains used to build the authorization headers. |
bf399285 |
493 | |
ea92acf7 |
494 | This list of domains defines the protection space. If a domain URI is an |
495 | absolute path (starts with /), it is relative to the root URL of the server being accessed. |
496 | An absolute URI in this list may refer to a different server than the one being accessed. |
497 | |
498 | The client will use this list to determine the set of URIs for which the same authentication |
499 | information may be sent. |
500 | |
501 | If this is omitted or its value is empty, the client will assume that the |
502 | protection space consists of all URIs on the responding server. |
503 | |
504 | Therefore, if your application is not hosted at the root of this domain, and you want to |
505 | prevent the authentication credentials for this application being sent to any other applications. |
506 | then you should use the I<use_uri_for> configuration option, and pass a domain of I</>. |
507 | |

d99b7693 |
509 | |
513d8ab6 |
510 | =item authenticate_basic $c, $realm, \%auth_info |
d99b7693 |
511 | |
bf399285 |
512 | Performs HTTP basic authentication. |
490754a8 |
513 | |
513d8ab6 |
514 | =item authenticate_digest $c, $realm, \%auth_info |
d99b7693 |
515 | |
bf399285 |
516 | Performs HTTP digest authentication. Note that the password_type B<must> by I<clear> for |
c5a1fa88 |
517 | digest authentication to succeed, and you must have L<Catalyst::Plugin::Session> in |
518 | your application as digest authentication needs to store persistent data. |
519 | |
520 | Note - if you do not want to store your user passwords as clear text, then it is possible |
521 | to store instead the MD5 digest in hex of the string '$username:$realm:$password' |
d99b7693 |
522 | |
ea92acf7 |
523 | Takes an additional parameter of I<algorithm>, the possible values of which are 'MD5' (the default) |
524 | and 'MD5-sess'. For more information about 'MD5-sess', see section 3.2.2.2 in RFC 2617. |
525 | |
513d8ab6 |
526 | =item authorization_required_response $c, $realm, \%auth_info |
d99b7693 |
527 | |
528 | Sets C<< $c->response >> to the correct status code, and adds the correct |
529 | header to demand authentication data from the user agent. |
530 | |
513d8ab6 |
531 | Typically used by C<authenticate>, but may be invoked manually. |
d99b7693 |
532 | |
513d8ab6 |
533 | %opts can contain C<domain> and C<algorithm>, which are used to build |
d99b7693 |
534 | %the digest header. |
535 | |
513d8ab6 |
536 | =item store_digest_authorization_nonce $c, $key, $nonce |
d99b7693 |
537 | |
513d8ab6 |
538 | =item get_digest_authorization_nonce $c, $key |
d99b7693 |
539 | |
540 | Set or get the C<$nonce> object used by the digest auth mode. |
541 | |
542 | You may override these methods. By default they will call C<get> and C<set> on |
543 | C<< $c->cache >>. |
544 | |
d99b7693 |
545 | =back |
546 | |
547 | =head1 CONFIGURATION |
548 | |
513d8ab6 |
549 | All configuration is stored in C<< YourApp->config(authentication => { yourrealm => { credential => { class => 'HTTP', %config } } } >>. |
d99b7693 |
550 | |
551 | This should be a hash, and it can contain the following entries: |
552 | |
05512a69 |
553 | =over |
d99b7693 |
554 | |
d99b7693 |
555 | =item type |
556 | |
557 | Can be either C<any> (the default), C<basic> or C<digest>. |
558 | |
513d8ab6 |
559 | This controls C<authorization_required_response> and C<authenticate>, but |
d99b7693 |
560 | not the "manual" methods. |
561 | |
562 | =item authorization_required_message |
563 | |
513d8ab6 |
564 | Set this to a string to override the default body content "Authorization required.", or set to undef to suppress body content being generated. |
d99b7693 |
565 | |
05512a69 |
566 | =item password_type |
567 | |
f1f73b53 |
568 | The type of password returned by the user object. Same usage as in |
b56120cd |
569 | L<Catalyst::Authentication::Credential::Password|Catalyst::Authentication::Credential::Password/password_type> |
05512a69 |
570 | |
571 | =item password_field |
572 | |
f1f73b53 |
573 | The name of accessor used to retrieve the value of the password field from the user object. Same usage as in |
05512a69 |
574 | L<Catalyst::Authentication::Credential::Password|Catalyst::Authentication::Credential::Password/password_field> |
575 | |
a50635bf |
576 | =item username_field |
577 | |
578 | The field name that the user's username is mapped into when finding the user from the realm. Defaults to 'username'. |
579 | |
05512a69 |
580 | =item use_uri_for |
581 | |
582 | If this configuration key has a true value, then the domain(s) for the authorization header will be |
ea92acf7 |
583 | run through $c->uri_for(). Use this configuration option if your application is not running at the root |
584 | of your domain, and you want to ensure that authentication credentials from your application are not shared with |
585 | other applications on the same server. |

589 | =head1 RESTRICTIONS |
590 | |
591 | When using digest authentication, this module will only work together |
592 | with authentication stores whose User objects have a C<password> |
593 | method that returns the plain-text password. It will not work together |
594 | with L<Catalyst::Authentication::Store::Htpasswd>, or |
513d8ab6 |
595 | L<Catalyst::Authentication::Store::DBIC> stores whose |
d99b7693 |
596 | C<password> methods return a hashed or salted version of the password. |
