488 | authentication framework. |

491 | |

501 | |
502 | =head1 DESCRIPTION |
503 | |
16ef3eb8 |
504 | The authentication plugin provides generic user support for Catalyst apps. It |
505 | is the basis for both authentication (checking the user is who they claim to |
506 | be), and authorization (allowing the user to do what the system authorises |
507 | them to do). |
508 | |
509 | Using authentication is split into two parts. A Store is used to actually |
510 | store the user information, and can store any amount of data related to the |
511 | user. Credentials are used to verify users, using information from the store, |
512 | given data from the frontend. A Credential and a Store are paired to form a |
e8919861 |
513 | 'Realm'. A Catalyst application using the authentication framework must have |
514 | at least one realm, and may have several. |
189b5b0c |
515 | |
6a36933d |
516 | To implement authentication in a Catalyst application you need to add this |
16ef3eb8 |
517 | module, and specify at least one realm in the configuration. |
189b5b0c |
518 | |
e7522758 |
519 | Authentication data can also be stored in a session, if the application |
520 | is using the L<Catalyst::Plugin::Session> module. |
06675d2e |
521 | |
30e90c6f |
522 | B<NOTE> in version 0.10 of this module, the interface to this module changed. |
523 | Please see L</COMPATIBILITY ROUTINES> for more information. |

525 | =head1 INTRODUCTION |
526 | |
527 | =head2 The Authentication/Authorization Process |
528 | |
529 | Web applications typically need to identify a user - to tell the user apart |
530 | from other users. This is usually done in order to display private information |
531 | that is only that user's business, or to limit access to the application so |
532 | that only certain entities can access certain parts. |
533 | |
534 | This process is split up into several steps. First you ask the user to identify |
535 | themselves. At this point you can't be sure that the user is really who they |
536 | claim to be. |
537 | |
6a36933d |
538 | Then the user tells you who they are, and backs this claim with some piece of |
4bb9b01c |
539 | information that only the real user could give you. For example, a password is |
540 | a secret that is known to both the user and you. When the user tells you this |
541 | password you can assume they're in on the secret and can be trusted (ignore |
542 | identity theft for now). Checking the password, or any other proof is called |
543 | B<credential verification>. |
544 | |
545 | By this time you know exactly who the user is - the user's identity is |
16ef3eb8 |
546 | B<authenticated>. This is where this module's job stops, and your application |
547 | or other plugins step in. |
548 | |
549 | The next logical step is B<authorization>, the process of deciding what a user |
550 | is (or isn't) allowed to do. For example, say your users are split into two |
551 | main groups - regular users and administrators. You want to verify that the |
4bb9b01c |
552 | currently logged in user is indeed an administrator before performing the |
c5fbff80 |
553 | actions in an administrative part of your application. These decisions may be |
16ef3eb8 |
554 | made within your application code using just the information available after |
555 | authentication, or it may be facilitated by a number of plugins. |
4bb9b01c |
556 | |
557 | =head2 The Components In This Framework |
558 | |
62f27384 |
559 | =head3 Realms |
560 | |
561 | Configuration of the Catalyst::Plugin::Authentication framework is done in |
562 | terms of realms. In simplest terms, a realm is a pairing of a Credential |
5afc0dde |
563 | verifier and a User storage (Store) backend. As of version 0.10003, realms are |
564 | now objects that you can create and customize. |
62f27384 |
565 | |
566 | An application can have any number of Realms, each of which operates |
34088132 |
567 | independent of the others. Each realm has a name, which is used to identify it |
62f27384 |
568 | as the target of an authentication request. This name can be anything, such as |
569 | 'users' or 'members'. One realm must be defined as the default_realm, which is |
16ef3eb8 |
570 | used when no realm name is specified. More information about configuring |
571 | realms is available in the configuration section. |
62f27384 |
572 | |
4bb9b01c |
573 | =head3 Credential Verifiers |
574 | |
4e86cf54 |
575 | When user input is transferred to the L<Catalyst> application |
576 | (typically via form inputs) the application may pass this information |
e979170b |
577 | into the authentication system through the C<< $c->authenticate() >> |
4e86cf54 |
578 | method. From there, it is passed to the appropriate Credential |
579 | verifier. |
4bb9b01c |
580 | |
581 | These plugins check the data, and ensure that it really proves the user is who |
582 | they claim to be. |
583 | |
4e86cf54 |
584 | Credential verifiers compatible with versions of this module 0.10x and |
585 | upwards should be in the namespace |
586 | C<Catalyst::Authentication::Credential>. |
587 | |
4bb9b01c |
588 | =head3 Storage Backends |
589 | |
45c7644b |
590 | The authentication data also identifies a user, and the Storage backend modules |
62f27384 |
591 | use this data to locate and return a standardized object-oriented |
592 | representation of a user. |
4bb9b01c |
593 | |
594 | When a user is retrieved from a store it is not necessarily authenticated. |
62f27384 |
595 | Credential verifiers accept a set of authentication data and use this |
596 | information to retrieve the user from the store they are paired with. |
4bb9b01c |
597 | |
34088132 |
598 | Storage backends compatible with versions of this module 0.10x and |
4e86cf54 |
599 | upwards should be in the namespace |
600 | C<Catalyst::Authentication::Store>. |
601 | |
4bb9b01c |
602 | =head3 The Core Plugin |
603 | |
62f27384 |
604 | This plugin on its own is the glue, providing realm configuration, session |
4bb9b01c |
605 | integration, and other goodness for the other plugins. |
606 | |
607 | =head3 Other Plugins |
608 | |
609 | More layers of plugins can be stacked on top of the authentication code. For |
610 | example, L<Catalyst::Plugin::Session::PerUser> provides an abstraction of |
4e86cf54 |
611 | browser sessions that is more persistent per user. |
4bb9b01c |
612 | L<Catalyst::Plugin::Authorization::Roles> provides an accepted way to separate |
613 | and group users into categories, and then check which categories the current |
614 | user belongs to. |
615 | |
5e91c057 |
616 | =head1 EXAMPLE |
617 | |
34088132 |
618 | Let's say we were storing users in a simple Perl hash. Users are |
16ef3eb8 |
619 | verified by supplying a password which is matched within the hash. |
5e91c057 |
620 | |
621 | This means that our application will begin like this: |
622 | |
623 | package MyApp; |
624 | |
625 | use Catalyst qw/ |
626 | Authentication |
5e91c057 |
627 | /; |
628 | |
c83ea211 |
629 | __PACKAGE__->config( 'Plugin::Authentication' => |
c5fbff80 |
630 | { |
bf4d93a4 |
631 | default => { |
632 | credential => { |
633 | class => 'Password', |
634 | password_field => 'password', |
635 | password_type => 'clear' |
636 | }, |
637 | store => { |
638 | class => 'Minimal', |
639 | users => { |
640 | bob => { |
641 | password => "s00p3r", |
642 | editor => 'yes', |
643 | roles => [qw/edit delete/], |
644 | }, |
645 | william => { |
646 | password => "s3cr3t", |
647 | roles => [qw/comment/], |
648 | } |
649 | } |
650 | } |
651 | } |
c83ea211 |
652 | } |
653 | ); |
5e91c057 |
654 | |
16ef3eb8 |
655 | This tells the authentication plugin what realms are available, which |
656 | credential and store modules are used, and the configuration of each. With |
657 | this code loaded, we can now attempt to authenticate users. |
5e91c057 |
658 | |
62f27384 |
659 | To show an example of this, let's create an authentication controller: |
5e91c057 |
660 | |
661 | package MyApp::Controller::Auth; |
662 | |
663 | sub login : Local { |
664 | my ( $self, $c ) = @_; |
665 | |
4e143b06 |
666 | if ( my $user = $c->req->params->{user} |
34088132 |
667 | and my $password = $c->req->params->{password} ) |
5e91c057 |
668 | { |
62f27384 |
669 | if ( $c->authenticate( { username => $user, |
670 | password => $password } ) ) { |
671 | $c->res->body( "hello " . $c->user->get("name") ); |
5e91c057 |
672 | } else { |
673 | # login incorrect |
674 | } |
675 | } |
676 | else { |
677 | # invalid form input |
678 | } |
679 | } |
680 | |
4e86cf54 |
681 | This code should be self-explanatory. If all the necessary fields are supplied, |
682 | call the C<authenticate> method on the context object. If it succeeds the |
c5fbff80 |
683 | user is logged in. |
5e91c057 |
684 | |
4e86cf54 |
685 | The credential verifier will attempt to retrieve the user whose |
686 | details match the authentication information provided to |
e979170b |
687 | C<< $c->authenticate() >>. Once it fetches the user the password is |
4e86cf54 |
688 | checked and if it matches the user will be B<authenticated> and |
e979170b |
689 | C<< $c->user >> will contain the user object retrieved from the store. |
5e91c057 |
690 | |
62f27384 |
691 | In the above case, the default realm is checked, but we could just as easily |
692 | check an alternate realm. If this were an admin login, for example, we could |
e979170b |
693 | authenticate on the admin realm by simply changing the C<< $c->authenticate() >> |
62f27384 |
694 | call: |
5e91c057 |
695 | |
62f27384 |
696 | if ( $c->authenticate( { username => $user, |
4e86cf54 |
697 | password => $password }, 'admin' ) ) { |
62f27384 |
698 | $c->res->body( "hello " . $c->user->get("name") ); |
699 | } ... |
5e91c057 |
700 | |
5e91c057 |
701 | |
c5fbff80 |
702 | Now suppose we want to restrict the ability to edit to a user with an |
703 | 'editor' value of yes. |
5e91c057 |
704 | |
62f27384 |
705 | The restricted action might look like this: |
5e91c057 |
706 | |
62f27384 |
707 | sub edit : Local { |
5e91c057 |
708 | my ( $self, $c ) = @_; |
709 | |
710 | $c->detach("unauthorized") |
711 | unless $c->user_exists |
c5fbff80 |
712 | and $c->user->get('editor') eq 'yes'; |
5e91c057 |
713 | |
714 | # do something restricted here |
715 | } |
716 | |
4e86cf54 |
717 | (Note that if you have multiple realms, you can use |
e979170b |
718 | C<< $c->user_in_realm('realmname') >> in place of |
719 | C<< $c->user_exists(); >> This will essentially perform the same |
4e86cf54 |
720 | verification as user_exists, with the added requirement that if there |
721 | is a user, it must have come from the realm specified.) |
c5fbff80 |
722 | |
723 | The above example is somewhat similar to role based access control. |
5c5af345 |
724 | L<Catalyst::Authentication::Store::Minimal> treats the roles field as |
62f27384 |
725 | an array of role names. Let's leverage this. Add the role authorization |
726 | plugin: |
5e91c057 |
727 | |
728 | use Catalyst qw/ |
729 | ... |
730 | Authorization::Roles |
731 | /; |
732 | |
62f27384 |
733 | sub edit : Local { |
5e91c057 |
734 | my ( $self, $c ) = @_; |
735 | |
128321cc |
736 | $c->detach("unauthorized") unless $c->check_user_roles("edit"); |
5e91c057 |
737 | |
738 | # do something restricted here |
739 | } |
740 | |
741 | This is somewhat simpler and will work if you change your store, too, since the |
742 | role interface is consistent. |
743 | |
34088132 |
744 | Let's say your app grows, and you now have 10,000 users. It's no longer |
0cc778ab |
745 | efficient to maintain a hash of users, so you move this data to a database. |
4e86cf54 |
746 | You can accomplish this simply by installing the L<DBIx::Class|Catalyst::Authentication::Store::DBIx::Class> Store and |
0cc778ab |
747 | changing your config: |
5e91c057 |
748 | |
c83ea211 |
749 | __PACKAGE__->config( 'Plugin::Authentication'} => |
0cc778ab |
750 | { |
751 | default_realm => 'members', |
0cc778ab |
752 | members => { |
753 | credential => { |
c5fbff80 |
754 | class => 'Password', |
755 | password_field => 'password', |
756 | password_type => 'clear' |
0cc778ab |
757 | }, |
758 | store => { |
759 | class => 'DBIx::Class', |
760 | user_class => 'MyApp::Users', |
761 | role_column => 'roles' |
762 | } |
0cc778ab |
763 | } |
c83ea211 |
764 | } |
765 | ); |
bf4d93a4 |
766 | |
767 | The authentication system works behind the scenes to load your data from the |
768 | new source. The rest of your application is completely unchanged. |

820 | anything in the session to prevent an unecessary session from being created. |

822 | =item default_realm |
fe4cf44a |
823 | |
0cc778ab |
824 | This defines which realm should be used as when no realm is provided to methods |
825 | that require a realm such as authenticate or find_user. |

828 | |

829 | The Plugin::Authentication config hash contains the series of realm |
830 | configurations you want to use for your app. The only rule here is |
831 | that there must be at least one. A realm consists of a name, which is used |
832 | to reference the realm, a credential and a store. You may also put your |
833 | realm configurations within a subelement called 'realms' if you desire to |
834 | separate them from the remainder of your configuration. Note that if you use |
835 | a 'realms' subelement, you must put ALL of your realms within it. |

836 | |
7c3d201d |
837 | You can also specify a realm class to instantiate instead of the default |
838 | L<Catalyst::Authentication::Realm> class using the 'class' element within the |
839 | realm config. |
5afc0dde |
840 | |
0cc778ab |
841 | Each realm config contains two hashes, one called 'credential' and one called |
842 | 'store', each of which provide configuration details to the respective modules. |
843 | The contents of these hashes is specific to the module being used, with the |
844 | exception of the 'class' element, which tells the core Authentication module the |
e8919861 |
845 | classname to instantiate. |
4fbe2e14 |
846 | |
0cc778ab |
847 | The 'class' element follows the standard Catalyst mechanism of class |
848 | specification. If a class is prefixed with a +, it is assumed to be a complete |
849 | class name. Otherwise it is considered to be a portion of the class name. For |
e8919861 |
850 | credentials, the classname 'B<Password>', for example, is expanded to |
5c5af345 |
851 | Catalyst::Authentication::Credential::B<Password>. For stores, the |
e8919861 |
852 | classname 'B<storename>' is expanded to: |
5c5af345 |
853 | Catalyst::Authentication::Store::B<storename>. |

857 | =head1 METHODS |
858 | |
34088132 |
859 | =head2 $c->authenticate( $userinfo [, $realm ]) |
e8919861 |
860 | |
861 | Attempts to authenticate the user using the information in the $userinfo hash |
862 | reference using the realm $realm. $realm may be omitted, in which case the |
863 | default realm is checked. |
864 | |
4e86cf54 |
865 | =head2 $c->user( ) |
e8919861 |
866 | |
34088132 |
867 | Returns the currently logged in user, or undef if there is none. |
e8919861 |
868 | |
4e86cf54 |
869 | =head2 $c->user_exists( ) |
e8919861 |
870 | |
871 | Returns true if a user is logged in right now. The difference between |
872 | user_exists and user is that user_exists will return true if a user is logged |
45c7644b |
873 | in, even if it has not been yet retrieved from the storage backend. If you only |
e8919861 |
874 | need to know if the user is logged in, depending on the storage mechanism this |
875 | can be much more efficient. |
876 | |
4e86cf54 |
877 | =head2 $c->user_in_realm( $realm ) |
45c7644b |
878 | |
879 | Works like user_exists, except that it only returns true if a user is both |
c5fbff80 |
880 | logged in right now and was retrieved from the realm provided. |
45c7644b |
881 | |
4e86cf54 |
882 | =head2 $c->logout( ) |
e8919861 |
883 | |
e979170b |
884 | Logs the user out. Deletes the currently logged in user from C<< $c->user >> and the session. |
e8919861 |
885 | |
4e86cf54 |
886 | =head2 $c->find_user( $userinfo, $realm ) |
e8919861 |
887 | |
888 | Fetch a particular users details, matching the provided user info, from the realm |
889 | specified in $realm. |
890 | |
8a7bd676 |
891 | =head2 persist_user() |
892 | |
893 | Under normal circumstances the user data is only saved to the session during |
894 | initial authentication. This call causes the auth system to save the |
34088132 |
895 | currently authenticated user's data across requests. Useful if you have |
8a7bd676 |
896 | changed the user data and want to ensure that future requests reflect the |
897 | most current data. Assumes that at the time of this call, $c->user |
898 | contains the most current data. |
899 | |
95114c34 |
900 | =head2 find_realm_for_persisted_user() |
901 | |
902 | Private method, do not call from user code! |
903 | |
06675d2e |
904 | =head1 INTERNAL METHODS |
905 | |
e8919861 |
906 | These methods are for Catalyst::Plugin::Authentication B<INTERNAL USE> only. |
907 | Please do not use them in your own code, whether application or credential / |
908 | store modules. If you do, you will very likely get the nasty shock of having |
909 | to fix / rewrite your code when things change. They are documented here only |
910 | for reference. |
06675d2e |
911 | |
4e86cf54 |
912 | =head2 $c->set_authenticated( $user, $realmname ) |
06675d2e |
913 | |
e8919861 |
914 | Marks a user as authenticated. This is called from within the authenticate |
915 | routine when a credential returns a user. $realmname defaults to 'default' |
06675d2e |
916 | |
4e86cf54 |
917 | =head2 $c->auth_restore_user( $user, $realmname ) |
e300c5b6 |
918 | |
e8919861 |
919 | Used to restore a user from the session. In most cases this is called without |
920 | arguments to restore the user via the session. Can be called with arguments |
921 | when restoring a user from some other method. Currently not used in this way. |
e300c5b6 |
922 | |
4e86cf54 |
923 | =head2 $c->auth_realms( ) |
06675d2e |
924 | |
e8919861 |
925 | Returns a hashref containing realmname -> realm instance pairs. Realm |
926 | instances contain an instantiated store and credential object as the 'store' |
927 | and 'credential' elements, respectively |
06675d2e |
928 | |
4e86cf54 |
929 | =head2 $c->get_auth_realm( $realmname ) |
06675d2e |
930 | |
e8919861 |
931 | Retrieves the realm instance for the realmname provided. |
06675d2e |
932 | |
96671824 |
933 | =head2 $c->update_user_in_session |
934 | |
34088132 |
935 | This was a short-lived method to update user information - you should use persist_user instead. |

1010 | This module along with its sub plugins deprecate a great number of other |
1011 | modules. These include L<Catalyst::Plugin::Authentication::Simple>, |
1012 | L<Catalyst::Plugin::Authentication::CDBI>. |

1014 | =head1 INCOMPATABILITIES |
1015 | |
34088132 |
1016 | The realms-based configuration and functionality of the 0.10 update |
649de93b |
1017 | of L<Catalyst::Plugin::Authentication> required a change in the API used by |
1018 | credentials and stores. It has a compatibility mode which allows use of |
1019 | modules that have not yet been updated. This, however, completely mimics the |
34088132 |
1020 | older api and disables the new realm-based features. In other words you cannot |
1021 | mix the older credential and store modules with realms, or realm-based |
649de93b |
1022 | configs. The changes required to update modules are relatively minor and are |
1023 | covered in L<Catalyst::Plugin::Authentication::Internals>. We hope that most |
1024 | modules will move to the compatible list above very quickly. |
0cc778ab |
1025 | |
ff87fb62 |
1026 | =head1 COMPATIBILITY CONFIGURATION |
1027 | |
1028 | Until version 0.10008 of this module, you needed to put all the |
1029 | realms inside a "realms" key in the configuration. |
1030 | |
1031 | # example |
c83ea211 |
1032 | __PACKAGE__->config( 'Plugin::Authentication'} => |
ff87fb62 |
1033 | { |
1034 | default_realm => 'members', |
1035 | realms => { |
1036 | members => { |
1037 | ... |
1038 | }, |
1039 | }, |
c83ea211 |
1040 | } |
1041 | ); |
ff87fb62 |
1042 | |
c83ea211 |
1043 | If you use the old, deprecated C<< __PACKAGE__->config( 'authentication' ) >> |
ff87fb62 |
1044 | configuration key, then the realms key is still required. |
1045 | |
0cc778ab |
1046 | =head1 COMPATIBILITY ROUTINES |
1047 | |
e8919861 |
1048 | In version 0.10 of L<Catalyst::Plugin::Authentication>, the API |
1049 | changed. For app developers, this change is fairly minor, but for |
1050 | Credential and Store authors, the changes are significant. |
1051 | |
1052 | Please see the documentation in version 0.09 of |
30e90c6f |
1053 | Catalyst::Plugin::Authentication for a better understanding of how the old API |
e8919861 |
1054 | functioned. |
1055 | |
1056 | The items below are still present in the plugin, though using them is |
1057 | deprecated. They remain only as a transition tool, for those sites which can |
30e90c6f |
1058 | not yet be upgraded to use the new system due to local customizations or use |
1059 | of Credential / Store modules that have not yet been updated to work with the |
45c7644b |
1060 | new API. |
e8919861 |
1061 | |
1062 | These routines should not be used in any application using realms |
1063 | functionality or any of the methods described above. These are for reference |
1064 | purposes only. |
0cc778ab |
1065 | |
4e86cf54 |
1066 | =head2 $c->login( ) |
e8919861 |
1067 | |
1068 | This method is used to initiate authentication and user retrieval. Technically |
649de93b |
1069 | this is part of the old Password credential module and it still resides in the |
1070 | L<Password|Catalyst::Plugin::Authentication::Credential::Password> class. It is |
1071 | included here for reference only. |
e8919861 |
1072 | |
4e86cf54 |
1073 | =head2 $c->default_auth_store( ) |
0cc778ab |
1074 | |
1075 | Return the store whose name is 'default'. |
1076 | |
c83ea211 |
1077 | This is set to C<< $c->config( 'Plugin::Authentication' => { store => # Store} ) >> if that value exists, |
0cc778ab |
1078 | or by using a Store plugin: |
1079 | |
30e90c6f |
1080 | # load the Minimal authentication store. |
0cc778ab |
1081 | use Catalyst qw/Authentication Authentication::Store::Minimal/; |
1082 | |
1083 | Sets the default store to |
45c7644b |
1084 | L<Catalyst::Plugin::Authentication::Store::Minimal>. |
0cc778ab |
1085 | |
4e86cf54 |
1086 | =head2 $c->get_auth_store( $name ) |
0cc778ab |
1087 | |
1088 | Return the store whose name is $name. |
1089 | |
4e86cf54 |
1090 | =head2 $c->get_auth_store_name( $store ) |
0cc778ab |
1091 | |
1092 | Return the name of the store $store. |
1093 | |
4e86cf54 |
1094 | =head2 $c->auth_stores( ) |
0cc778ab |
1095 | |
1096 | A hash keyed by name, with the stores registered in the app. |
1097 | |
4e86cf54 |
1098 | =head2 $c->register_auth_stores( %stores_by_name ) |
0cc778ab |
1099 | |
1100 | Register stores into the application. |
