64 This plugin implements the Catalyst::Authentication v.10 API. Read that
65 documentation first if you are upgrading from a previous version of this
68 This plugin uses "Net::LDAP" to let your application authenticate
69 against an LDAP directory. It has a pretty high degree of flexibility,
70 given the wide variation of LDAP directories and schemas from one system
73 It authenticates users in two steps:
75 1) A search of the directory is performed, looking for a user object
76 that matches the username you pass. This is done with the bind
77 credentials supplied in the "binddn" and "bindpw" configuration options.
79 2) If that object is found, we then re-bind to the directory as that
80 object. Assuming this is successful, the user is Authenticated.
84 Set Configuration to be loaded via Config.yml in YourApp.pm
86 use YAML qw(LoadFile);
87 use Path::Class 'file';
91 file(__PACKAGE__->config->{home}, 'Config.yml')
95 Settings in Config.yml (adapt these to whatever configuration format you
98 # Config for Store::LDAP
105 password_field: password
106 password_type: self_check
109 ldap_server: ldap.yourcompany.com
117 user_basedn: ou=people,dc=yourcompany,dc=com
118 user_filter: (&(objectClass=posixAccount)(uid=%s))
124 role_basedn: ou=groups,ou=OxObjects,dc=yourcompany,dc=com
125 role_filter: (&(objectClass=posixGroup)(memberUid=%s))
132 NOTE: The settings above reflect the default values for OpenLDAP. If you
133 are using Active Directory instead, Matija Grabnar suggests that the
134 following tweeks to the example configuration will work:
136 user_basedn: ou=Domain Users,ou=Accounts,dc=mycompany,dc=com
137 user_field: samaccountname
138 user_filter: (sAMAccountName=%s)
141 He also notes: "I found the case in the value of user_field to be
142 significant: it didn't seem to work when I had the mixed case value
146 This should be the hostname of your LDAP server.
149 This should be a hashref containing options to pass to Net::LDAP->new().
150 See Net::LDAP for the full list.
153 This should be the DN of the object you wish to bind to the directory as
154 during the first phase of authentication. (The user lookup phase)
156 If you supply the value "anonymous" to this option, we will bind
157 anonymously to the directory. This is the default.
160 This is the password for the initial bind.
163 If this is set to 1, we will convert the LDAP connection to use SSL.
166 This is a hashref, which contains the arguments to the Net::LDAP
167 start_tls method. See Net::LDAP for the complete list of options.
170 This is the basedn for the initial user lookup. Usually points to the
171 top of your "users" branch; ie "ou=people,dc=yourcompany,dc=com".
174 This is the LDAP Search filter used during user lookup. The special
175 string '%s' will be replaced with the username you pass to $c->login. By
176 default it is set to '(uid=%s)'. Other possibly useful filters:
178 (&(objectClass=posixAccount)(uid=%s))
179 (&(objectClass=User)(cn=%s))
182 This specifies the scope of the search for the initial user lookup.
183 Valid values are "base", "one", and "sub". Defaults to "sub".
186 This is the attribute of the returned LDAP object we will use for their
187 "username". This defaults to "uid". If you had user_filter set to:
189 (&(objectClass=User)(cn=%s))
191 You would probably set this to "cn". You can also set it to an array, to
192 allow more than one login field. The first field will be returned as
193 identifier for the user.
196 This takes a hashref. It will append it's values to the call to
197 Net::LDAP's "search" method during the initial user lookup. See
198 Net::LDAP for valid options.
200 Be careful not to specify:
206 As they are already taken care of by other configuration options.
209 This is a Perl CODE ref that can be used to filter out multiple results
210 from your LDAP query. In theory, your LDAP query should only return one
211 result and find_user() will throw an exception if it encounters more
212 than one result. However, if you have, for whatever reason, a legitimate
213 reason for returning multiple search results from your LDAP query, use
214 "user_results_filter" to filter out the LDAP entries you do not want
215 considered. Your CODE ref should expect a single argument, a
216 Net::LDAP::Search object, and it should return exactly one value, a
217 Net::LDAP::Entry object.
221 user_results_filter => sub {
222 my $search_obj = shift;
223 foreach my $entry ($search_obj->entries) {
224 return $entry if my_match_logic( $entry );
226 return undef; # i.e., no match
230 Whether or not to enable role lookups. It defaults to true; set it to 0
231 if you want to always avoid role lookups.
234 This should be the basedn where the LDAP Objects representing your roles
238 This should be the LDAP Search filter to use during the role lookup. It
239 defaults to '(memberUid=%s)'. The %s in this filter is replaced with the
240 value of the "role_value" configuration option.
242 So, if you had a role_value of "cn", then this would be populated with
243 the cn of the User's LDAP object. The special case is a role_value of
244 "dn", which will be replaced with the User's DN.
247 This specifies the scope of the search for the user's role lookup. Valid
248 values are "base", "one", and "sub". Defaults to "sub".
251 Should be set to the Attribute of the Role Object's returned during Role
252 lookup you want to use as the "name" of the role. Defaults to "CN".
255 This is the attribute of the User object we want to use in our
256 role_filter. If this is set to "dn", we will use the User Objects DN.
259 This takes a hashref. It will append it's values to the call to
260 Net::LDAP's "search" method during the user's role lookup. See Net::LDAP
263 Be careful not to specify:
269 As they are already taken care of by other configuration options.
272 By default this setting is false, and the role search will be performed
273 by binding to the directory with the details in the *binddn* and
274 *bindpw* fields. If this is set to false, then the role search will
275 instead be performed when bound as the user you authenticated as.
278 Can take one of the following values, defaults to "username":
281 Only store the username in the session and lookup the user and its
282 roles on every request. That was how the module worked until version
283 1.015 and is also the default for backwards compatibility.
286 Store the user object and its roles in the session and never look it
287 up in the store after login.
289 NOTE: It's recommended to limit the user attributes fetched from
290 LDAP using user_search_options / attrs to not exhaust the session
294 The name of the class of LDAP entries returned. This class should exist
295 and is expected to be a subclass of Net::LDAP::Entry
298 The name of the class of user object returned. By default, this is
299 Catalyst::Authentication::Store::LDAP::User.
303 This method will populate "default_auth_store" in
304 Catalyst::Plugin::Authentication with this object.
