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
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
513 'Realm'. A Catalyst application using the authentication framework must have
514 at least one realm, and may have several.
516 To implement authentication in a Catalyst application you need to add this
517 module, and specify at least one realm in the configuration.
519 Authentication data can also be stored in a session, if the application
520 is using the L<Catalyst::Plugin::Session> module.
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.
527 =head2 The Authentication/Authorization Process
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.
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
538 Then the user tells you who they are, and backs this claim with some piece of
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>.
545 By this time you know exactly who the user is - the user's identity is
546 B<authenticated>. This is where this module's job stops, and your application
547 or other plugins step in.
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
552 currently logged in user is indeed an administrator before performing the
553 actions in an administrative part of your application. These decisions may be
554 made within your application code using just the information available after
555 authentication, or it may be facilitated by a number of plugins.
557 =head2 The Components In This Framework
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
563 verifier and a User storage (Store) backend. As of version 0.10003, realms are
564 now objects that you can create and customize.
566 An application can have any number of Realms, each of which operates
567 independent of the others. Each realm has a name, which is used to identify it
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
570 used when no realm name is specified. More information about configuring
571 realms is available in the configuration section.
573 =head3 Credential Verifiers
575 When user input is transferred to the L<Catalyst> application
576 (typically via form inputs) the application may pass this information
577 into the authentication system through the C<< $c->authenticate() >>
578 method. From there, it is passed to the appropriate Credential
581 These plugins check the data, and ensure that it really proves the user is who
584 Credential verifiers compatible with versions of this module 0.10x and
585 upwards should be in the namespace
586 C<Catalyst::Authentication::Credential>.
588 =head3 Storage Backends
590 The authentication data also identifies a user, and the Storage backend modules
591 use this data to locate and return a standardized object-oriented
592 representation of a user.
594 When a user is retrieved from a store it is not necessarily authenticated.
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.
598 Storage backends compatible with versions of this module 0.10x and
599 upwards should be in the namespace
600 C<Catalyst::Authentication::Store>.
602 =head3 The Core Plugin
604 This plugin on its own is the glue, providing realm configuration, session
605 integration, and other goodness for the other plugins.
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
611 browser sessions that is more persistent per user.
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
618 Let's say we were storing users in a simple Perl hash. Users are
619 verified by supplying a password which is matched within the hash.
621 This means that our application will begin like this:
629 __PACKAGE__->config->{'Plugin::Authentication'} =
634 password_field => 'password',
635 password_type => 'clear'
641 password => "s00p3r",
643 roles => [qw/edit delete/],
646 password => "s3cr3t",
647 roles => [qw/comment/],
654 This tells the authentication plugin what realms are available, which
655 credential and store modules are used, and the configuration of each. With
656 this code loaded, we can now attempt to authenticate users.
658 To show an example of this, let's create an authentication controller:
660 package MyApp::Controller::Auth;
663 my ( $self, $c ) = @_;
665 if ( my $user = $c->req->params->{user}
666 and my $password = $c->req->params->{password} )
668 if ( $c->authenticate( { username => $user,
669 password => $password } ) ) {
670 $c->res->body( "hello " . $c->user->get("name") );
680 This code should be self-explanatory. If all the necessary fields are supplied,
681 call the C<authenticate> method on the context object. If it succeeds the
684 The credential verifier will attempt to retrieve the user whose
685 details match the authentication information provided to
686 C<< $c->authenticate() >>. Once it fetches the user the password is
687 checked and if it matches the user will be B<authenticated> and
688 C<< $c->user >> will contain the user object retrieved from the store.
690 In the above case, the default realm is checked, but we could just as easily
691 check an alternate realm. If this were an admin login, for example, we could
692 authenticate on the admin realm by simply changing the C<< $c->authenticate() >>
695 if ( $c->authenticate( { username => $user,
696 password => $password }, 'admin' ) ) {
697 $c->res->body( "hello " . $c->user->get("name") );
701 Now suppose we want to restrict the ability to edit to a user with an
702 'editor' value of yes.
704 The restricted action might look like this:
707 my ( $self, $c ) = @_;
709 $c->detach("unauthorized")
710 unless $c->user_exists
711 and $c->user->get('editor') eq 'yes';
713 # do something restricted here
716 (Note that if you have multiple realms, you can use
717 C<< $c->user_in_realm('realmname') >> in place of
718 C<< $c->user_exists(); >> This will essentially perform the same
719 verification as user_exists, with the added requirement that if there
720 is a user, it must have come from the realm specified.)
722 The above example is somewhat similar to role based access control.
723 L<Catalyst::Authentication::Store::Minimal> treats the roles field as
724 an array of role names. Let's leverage this. Add the role authorization
733 my ( $self, $c ) = @_;
735 $c->detach("unauthorized") unless $c->check_user_roles("edit");
737 # do something restricted here
740 This is somewhat simpler and will work if you change your store, too, since the
741 role interface is consistent.
743 Let's say your app grows, and you now have 10,000 users. It's no longer
744 efficient to maintain a hash of users, so you move this data to a database.
745 You can accomplish this simply by installing the L<DBIx::Class|Catalyst::Authentication::Store::DBIx::Class> Store and
746 changing your config:
748 __PACKAGE__->config->{'Plugin::Authentication'} =
750 default_realm => 'members',
754 password_field => 'password',
755 password_type => 'clear'
758 class => 'DBIx::Class',
759 user_class => 'MyApp::Users',
760 role_column => 'roles'
765 The authentication system works behind the scenes to load your data from the
766 new source. The rest of your application is completely unchanged.
772 __PACKAGE__->config->{'Plugin::Authentication'} =
774 default_realm => 'members',
779 password_field => 'password',
780 password_type => 'clear'
783 class => 'DBIx::Class',
784 user_class => 'MyApp::Users',
785 role_column => 'roles'
791 password_field => 'password',
792 password_type => 'clear'
795 class => '+MyApp::Authentication::Store::NetAuth',
796 authserver => '192.168.10.17'
805 Whether or not to store the user's logged in state in the session, if the
806 application is also using L<Catalyst::Plugin::Session>. This
807 value is set to true per default.
811 This defines which realm should be used as when no realm is provided to methods
812 that require a realm such as authenticate or find_user.
816 The Plugin::Authentication config hash contains the series of realm
817 configurations you want to use for your app. The only rule here is
818 that there must be at least one. A realm consists of a name, which is used
819 to reference the realm, a credential and a store. You may also put your
820 realm configurations within a subelement called 'realms' if you desire to
821 separate them from the remainder of your configuration. Note that if you use
822 a 'realms' subelement, you must put ALL of your realms within it.
824 You can also specify a realm class to instantiate instead of the default
825 L<Catalyst::Authentication::Realm> class using the 'class' element within the
828 Each realm config contains two hashes, one called 'credential' and one called
829 'store', each of which provide configuration details to the respective modules.
830 The contents of these hashes is specific to the module being used, with the
831 exception of the 'class' element, which tells the core Authentication module the
832 classname to instantiate.
834 The 'class' element follows the standard Catalyst mechanism of class
835 specification. If a class is prefixed with a +, it is assumed to be a complete
836 class name. Otherwise it is considered to be a portion of the class name. For
837 credentials, the classname 'B<Password>', for example, is expanded to
838 Catalyst::Authentication::Credential::B<Password>. For stores, the
839 classname 'B<storename>' is expanded to:
840 Catalyst::Authentication::Store::B<storename>.
846 =head2 $c->authenticate( $userinfo [, $realm ])
848 Attempts to authenticate the user using the information in the $userinfo hash
849 reference using the realm $realm. $realm may be omitted, in which case the
850 default realm is checked.
854 Returns the currently logged in user, or undef if there is none.
856 =head2 $c->user_exists( )
858 Returns true if a user is logged in right now. The difference between
859 user_exists and user is that user_exists will return true if a user is logged
860 in, even if it has not been yet retrieved from the storage backend. If you only
861 need to know if the user is logged in, depending on the storage mechanism this
862 can be much more efficient.
864 =head2 $c->user_in_realm( $realm )
866 Works like user_exists, except that it only returns true if a user is both
867 logged in right now and was retrieved from the realm provided.
871 Logs the user out. Deletes the currently logged in user from C<< $c->user >> and the session.
873 =head2 $c->find_user( $userinfo, $realm )
875 Fetch a particular users details, matching the provided user info, from the realm
878 =head2 persist_user()
880 Under normal circumstances the user data is only saved to the session during
881 initial authentication. This call causes the auth system to save the
882 currently authenticated user's data across requests. Useful if you have
883 changed the user data and want to ensure that future requests reflect the
884 most current data. Assumes that at the time of this call, $c->user
885 contains the most current data.
887 =head2 find_realm_for_persisted_user()
889 Private method, do not call from user code!
891 =head1 INTERNAL METHODS
893 These methods are for Catalyst::Plugin::Authentication B<INTERNAL USE> only.
894 Please do not use them in your own code, whether application or credential /
895 store modules. If you do, you will very likely get the nasty shock of having
896 to fix / rewrite your code when things change. They are documented here only
899 =head2 $c->set_authenticated( $user, $realmname )
901 Marks a user as authenticated. This is called from within the authenticate
902 routine when a credential returns a user. $realmname defaults to 'default'
904 =head2 $c->auth_restore_user( $user, $realmname )
906 Used to restore a user from the session. In most cases this is called without
907 arguments to restore the user via the session. Can be called with arguments
908 when restoring a user from some other method. Currently not used in this way.
910 =head2 $c->auth_realms( )
912 Returns a hashref containing realmname -> realm instance pairs. Realm
913 instances contain an instantiated store and credential object as the 'store'
914 and 'credential' elements, respectively
916 =head2 $c->get_auth_realm( $realmname )
918 Retrieves the realm instance for the realmname provided.
920 =head2 $c->update_user_in_session
922 This was a short-lived method to update user information - you should use persist_user instead.
926 This list might not be up to date. Below are modules known to work with the updated
927 API of 0.10 and are therefore compatible with realms.

956 =head1 DON'T SEE ALSO
958 This module along with its sub plugins deprecate a great number of other
959 modules. These include L<Catalyst::Plugin::Authentication::Simple>,
960 L<Catalyst::Plugin::Authentication::CDBI>.
962 At the time of writing these plugins have not yet been replaced or updated, but
963 should be eventually: L<Catalyst::Plugin::Authentication::OpenID>,
964 L<Catalyst::Plugin::Authentication::CDBI::Basic>,
965 L<Catalyst::Plugin::Authentication::Basic::Remote>.
967 =head1 INCOMPATABILITIES
969 The realms-based configuration and functionality of the 0.10 update
970 of L<Catalyst::Plugin::Authentication> required a change in the API used by
971 credentials and stores. It has a compatibility mode which allows use of
972 modules that have not yet been updated. This, however, completely mimics the
973 older api and disables the new realm-based features. In other words you cannot
974 mix the older credential and store modules with realms, or realm-based
975 configs. The changes required to update modules are relatively minor and are
976 covered in L<Catalyst::Plugin::Authentication::Internals>. We hope that most
977 modules will move to the compatible list above very quickly.
979 =head1 COMPATIBILITY ROUTINES
981 In version 0.10 of L<Catalyst::Plugin::Authentication>, the API
982 changed. For app developers, this change is fairly minor, but for
983 Credential and Store authors, the changes are significant.
985 Please see the documentation in version 0.09 of
986 Catalyst::Plugin::Authentication for a better understanding of how the old API
989 The items below are still present in the plugin, though using them is
990 deprecated. They remain only as a transition tool, for those sites which can
991 not yet be upgraded to use the new system due to local customizations or use
992 of Credential / Store modules that have not yet been updated to work with the
995 These routines should not be used in any application using realms
996 functionality or any of the methods described above. These are for reference
1001 This method is used to initiate authentication and user retrieval. Technically
1002 this is part of the old Password credential module and it still resides in the
1003 L<Password|Catalyst::Plugin::Authentication::Credential::Password> class. It is
1004 included here for reference only.
1006 =head2 $c->default_auth_store( )
1008 Return the store whose name is 'default'.
1010 This is set to C<< $c->config->{'Plugin::Authentication'}{store} >> if that value exists,
1011 or by using a Store plugin:
1013 # load the Minimal authentication store.
1014 use Catalyst qw/Authentication Authentication::Store::Minimal/;
1016 Sets the default store to
1017 L<Catalyst::Plugin::Authentication::Store::Minimal>.
1019 =head2 $c->get_auth_store( $name )
1021 Return the store whose name is $name.
1023 =head2 $c->get_auth_store_name( $store )
1025 Return the name of the store $store.
1027 =head2 $c->auth_stores( )
1029 A hash keyed by name, with the stores registered in the app.
1031 =head2 $c->register_auth_stores( %stores_by_name )
1033 Register stores into the application.
1035 =head2 $c->auth_store_names( )
