6 Catalyst::Authentication::Store::LDAP::User
7 - A User object representing an LDAP object.
11 You should be creating these objects through L<Catalyst::Authentication::Store::LDAP::Backend>'s "get_user" method, or just letting $c->authenticate do
15 my ( $self, $c ) = @_;
17 id => $c->req->param(username),
18 password => $c->req->param(password)
20 $c->log->debug($c->user->username . "is really neat!");
23 If you access just $c->user in a scalar context, it will return the current
28 This wraps up an LDAP object and presents a simplified interface to it's
29 contents. It uses some AUTOLOAD magic to pass method calls it doesn't
30 understand through as simple read only accessors for the LDAP entries
33 It gets grumpy if you ask for an attribute via the AUTOLOAD mechanism
34 that it doesn't know about. Avoid that with using "has_attribute",
35 discussed in more detail below.
37 You can skip all that and just go straight to the L<Net::LDAP::Entry>
38 object through the "ldap_entry" method:
40 my $entry = $c->user->ldap_entry;
42 It also has support for Roles.
46 package Catalyst::Authentication::Store::LDAP::User;
47 use base qw( Catalyst::Authentication::User Class::Accessor::Fast );
51 use Scalar::Util qw/refaddr/;
53 our $VERSION = '1.014';
55 BEGIN { __PACKAGE__->mk_accessors(qw/user store/) }
57 use overload '""' => sub { shift->stringify }, fallback => 1;
59 my %_ldap_connection_passwords; # Store inside-out so that they don't show up
64 =head2 new($store, $user, $c)
66 Takes a L<Catalyst::Authentication::Store::LDAP::Backend> object
67 as $store, and the data structure returned by that class's "get_user"
68 method as $user. The final argument is an instance of your application,
69 which is passed along for those wanting to subclass User and perhaps use
70 models for fetching data.
72 Returns a L<Catalyst::Authentication::Store::LDAP::User> object.
77 my ( $class, $store, $user, $c ) = @_;
81 bless { store => $store, user => $user, }, $class;
86 Returns the results of the "stringify" method.
92 return $self->stringify;
97 Uses the "user_field" configuration option to determine what the "username"
98 of this object is, and returns it.
100 If you use the special value "dn" for user_field, it will return the DN
101 of the L<Net::LDAP::Entry> object.
107 my $userfield = $self->store->user_field;
108 $userfield = $$userfield[0] if ref $userfield eq 'ARRAY';
109 if ( $userfield eq "dn" ) {
110 my ($string) = $self->user->ldap_entry->dn;
114 my $val = $self->$userfield;
115 return ref($val) eq 'ARRAY' ? $val->[0] : $val;
119 =head2 supported_features
121 Returns hashref of features that this Authentication::User subclass supports.
125 sub supported_features {
127 password => { self_check => 1, },
129 roles => { self_check => 0, },
133 =head2 check_password($password)
135 Bind's to the directory as the DN of the internal L<Net::LDAP::Entry> object,
136 using the bind password supplied in $password. Returns 1 on a successful
142 my ( $self, $password ) = @_;
144 = $self->store->ldap_bind( undef, $self->ldap_entry->dn, $password,
146 if ( defined($ldap) ) {
147 # Stash a closure which can be used to retrieve the connection in the users context later.
148 $_ldap_connection_passwords{refaddr($self)} = $password;
158 Returns the results of L<Catalyst::Authentication::Store::LDAP::Backend>'s "lookup_roles" method, an array of roles that are valid for this user.
164 $self->{_roles} ||= [$self->store->lookup_roles($self)];
165 return @{$self->{_roles}};
170 Returns the User object, stringified.
176 return $self->stringify;
181 Returns the raw ldap_entry.
187 return $self->user->{'ldap_entry'};
190 =head2 attributes($type)
192 Returns an array of attributes present for this user. If $type is "ashash",
193 it will return a hash with the attribute names as keys. (And the values of
194 those attributes as, well, the values of the hash)
199 my ( $self, $type ) = @_;
200 if ( $type eq "ashash" ) {
201 return $self->user->{'attributes'};
204 return keys( %{ $self->user->{'attributes'} } );
210 Returns the values for an attribute, or undef if that attribute is not present.
211 The safest way to get at an attribute.
216 my ( $self, $attribute ) = @_;
217 if ( !defined($attribute) ) {
218 Catalyst::Exception->throw(
219 "You must provide an attribute to has_attribute!");
221 if ( $attribute eq "dn" ) {
222 return $self->ldap_entry->dn;
224 elsif ( $attribute eq "username" ) {
225 return $self->user->{'attributes'}->{$self->store->user_field};
227 elsif ( exists( $self->user->{'attributes'}->{$attribute} ) ) {
228 return $self->user->{'attributes'}->{$attribute};
237 A simple wrapper around has_attribute() to satisfy the Catalyst::Authentication::User API.
241 sub get { return shift->has_attribute(@_) }
245 Satisfies the Catalyst::Authentication::User API and returns the contents of the user()
250 sub get_object { return shift->user }
252 =head2 ldap_connection
254 Re-binds to the auth store with the credentials of the user you logged in
255 as, and returns a L<Net::LDAP> object which you can use to do further queries.
259 sub ldap_connection {
261 $self->store->ldap_bind( undef, $self->ldap_entry->dn,
262 $_ldap_connection_passwords{refaddr($self)} );
265 =head2 AUTOLOADed methods
267 We automatically map the attributes of the underlying L<Net::LDAP::Entry>
268 object to read-only accessor methods. So, if you have an entry that looks
271 dn: cn=adam,ou=users,dc=yourcompany,dc=com
274 homeDirectory: /home/adam
278 mail: adam@yourcompany.com
282 objectClass: inetOrgPerson
283 objectClass: organizationalPerson
286 objectClass: posixAccount
290 $c->user->homedirectory
292 And you'll get the value of the "homeDirectory" attribute. Note that
293 all the AUTOLOADed methods are automatically lower-cased.
295 =head2 Special Keywords
297 The highly useful and common method "username" will map to the configured
298 value of user_field (uid by default.)
300 $c->user->username == $c->user->uid
306 # Don't leak passwords..
307 delete $_ldap_connection_passwords{refaddr($self)};
311 my ($self, $method) = @_;
313 return $self->SUPER::can($method) || do {
314 return unless $self->has_attribute($method);
315 return sub { $_[0]->has_attribute($method) };
322 ( my $method ) = ( our $AUTOLOAD =~ /([^:]+)$/ );
324 if ( $method eq "DESTROY" ) {
328 if ( my $attribute = $self->has_attribute($method) ) {
332 Catalyst::Exception->throw(
333 "No attribute $method for User " . $self->stringify );
