82 | =head1 DESCRIPTION |
83 | |
84 | This plugin implements the L<Catalyst::Authentication> v.10 API. Read that documentation first if |
85 | you are upgrading from a previous version of this plugin. |
86 | |
87 | This plugin uses C<Net::LDAP> to let your application authenticate against |
88 | an LDAP directory. It has a pretty high degree of flexibility, given the |
89 | wide variation of LDAP directories and schemas from one system to another. |
90 | |
91 | It authenticates users in two steps: |
92 | |
93 | 1) A search of the directory is performed, looking for a user object that |
94 | matches the username you pass. This is done with the bind credentials |
95 | supplied in the "binddn" and "bindpw" configuration options. |
96 | |
97 | 2) If that object is found, we then re-bind to the directory as that object. |
98 | Assuming this is successful, the user is Authenticated. |
99 | |
100 | =head1 CONFIGURATION OPTIONS |
101 | |
102 | =head2 Configuring with YAML |
103 | |
104 | Set Configuration to be loaded via Config.yml in YourApp.pm |
105 | |
106 | use YAML qw(LoadFile); |
107 | use Path::Class 'file'; |
108 | |
109 | __PACKAGE__->config( |
110 | LoadFile( |
111 | file(__PACKAGE__->config->{home}, 'Config.yml') |
112 | ) |
113 | ); |
114 | |
115 | Settings in Config.yml (adapt these to whatever configuration format you use): |
116 | |
117 | # Config for Store::LDAP |
118 | authentication: |
119 | default_realm: ldap |
120 | realms: |
121 | ldap: |
122 | credential: |
123 | class: Password |
124 | password_field: password |
125 | password_type: self_check |
126 | store: |
127 | class: LDAP |
128 | ldap_server: ldap.yourcompany.com |
129 | ldap_server_options: |
130 | timeout: 30 |
131 | binddn: anonymous |
132 | bindpw: dontcarehow |
133 | start_tls: 1 |
134 | start_tls_options: |
135 | verify: none |
136 | user_basedn: ou=people,dc=yourcompany,dc=com |
137 | user_filter: (&(objectClass=posixAccount)(uid=%s)) |
138 | user_scope: one |
139 | user_field: uid |
140 | user_search_options: |
141 | deref: always |
142 | use_roles: 1 |
143 | role_basedn: ou=groups,ou=OxObjects,dc=yourcompany,dc=com |
144 | role_filter: (&(objectClass=posixGroup)(memberUid=%s)) |
145 | role_scope: one |
146 | role_field: uid |
147 | role_value: dn |
148 | role_search_options: |
149 | deref: always |
150 | |
151 | |
152 | B<NOTE:> The settings above reflect the default values for OpenLDAP. If you |
153 | are using Active Directory instead, Matija Grabnar suggests that the following |
154 | tweeks to the example configuration will work: |
155 | |
156 | user_basedn: ou=Domain Users,ou=Accounts,dc=mycompany,dc=com |
157 | user_field: samaccountname |
158 | user_filter: (sAMAccountName=%s) |
159 | |
160 | He also notes: "I found the case in the value of user_field to be significant: |
161 | it didn't seem to work when I had the mixed case value there." |
162 | |
163 | =head2 ldap_server |
164 | |
165 | This should be the hostname of your LDAP server. |
166 | |
167 | =head2 ldap_server_options |
168 | |
169 | This should be a hashref containing options to pass to L<Net::LDAP>->new(). |
170 | See L<Net::LDAP> for the full list. |
171 | |
172 | =head2 binddn |
173 | |
174 | This should be the DN of the object you wish to bind to the directory as |
175 | during the first phase of authentication. (The user lookup phase) |
176 | |
177 | If you supply the value "anonymous" to this option, we will bind anonymously |
178 | to the directory. This is the default. |
179 | |
180 | =head2 bindpw |
181 | |
182 | This is the password for the initial bind. |
183 | |
184 | =head2 start_tls |
185 | |
186 | If this is set to 1, we will convert the LDAP connection to use SSL. |
187 | |
188 | =head2 start_tls_options |
189 | |
190 | This is a hashref, which contains the arguments to the L<Net::LDAP> start_tls |
191 | method. See L<Net::LDAP> for the complete list of options. |
192 | |
193 | =head2 user_basedn |
194 | |
195 | This is the basedn for the initial user lookup. Usually points to the |
196 | top of your "users" branch; ie "ou=people,dc=yourcompany,dc=com". |
197 | |
198 | =head2 user_filter |
199 | |
200 | This is the LDAP Search filter used during user lookup. The special string |
201 | '%s' will be replaced with the username you pass to $c->login. By default |
202 | it is set to '(uid=%s)'. Other possibly useful filters: |
203 | |
204 | (&(objectClass=posixAccount)(uid=%s)) |
205 | (&(objectClass=User)(cn=%s)) |
206 | |
207 | =head2 user_scope |
208 | |
209 | This specifies the scope of the search for the initial user lookup. Valid |
210 | values are "base", "one", and "sub". Defaults to "sub". |
211 | |
212 | =head2 user_field |
213 | |
214 | This is the attribute of the returned LDAP object we will use for their |
215 | "username". This defaults to "uid". If you had user_filter set to: |
216 | |
217 | (&(objectClass=User)(cn=%s)) |
218 | |
219 | You would probably set this to "cn". You can also set it to an array, |
220 | to allow more than one login field. The first field will be returned |
221 | as identifier for the user. |
222 | |
223 | =head2 user_search_options |
224 | |
225 | This takes a hashref. It will append it's values to the call to |
226 | L<Net::LDAP>'s "search" method during the initial user lookup. See |
227 | L<Net::LDAP> for valid options. |
228 | |
229 | Be careful not to specify: |
230 | |
231 | filter |
232 | scope |
233 | base |
234 | |
235 | As they are already taken care of by other configuration options. |
236 | |
1647b33a |
237 | =head2 user_results_filter |
238 | |
239 | This is a Perl CODE ref that can be used to filter out multiple results |
240 | from your LDAP query. In theory, your LDAP query should only return one result |
241 | and find_user() will throw an exception if it encounters more than one result. |
242 | However, if you have, for whatever reason, a legitimate reason for returning |
243 | multiple search results from your LDAP query, use C<user_results_filter> to filter |
244 | out the LDAP entries you do not want considered. Your CODE ref should expect |
245 | a single argument, a Net::LDAP::Search object, and it should return exactly one |
246 | value, a Net::LDAP::Entry object. |
247 | |
248 | Example: |
249 | |
250 | user_results_filter => sub { |
251 | my $search_obj = shift; |
252 | foreach my $entry ($search_obj->entries) { |
253 | return $entry if my_match_logic( $entry ); |
254 | } |
255 | return undef; # i.e., no match |
256 | } |
257 | |
f66d606b |
258 | =head2 use_roles |
259 | |
260 | Whether or not to enable role lookups. It defaults to true; set it to 0 if |
261 | you want to always avoid role lookups. |
262 | |
263 | =head2 role_basedn |
264 | |
265 | This should be the basedn where the LDAP Objects representing your roles are. |
266 | |
267 | =head2 role_filter |
268 | |
269 | This should be the LDAP Search filter to use during the role lookup. It |
270 | defaults to '(memberUid=%s)'. The %s in this filter is replaced with the value |
271 | of the "role_value" configuration option. |
272 | |
273 | So, if you had a role_value of "cn", then this would be populated with the cn |
274 | of the User's LDAP object. The special case is a role_value of "dn", which |
275 | will be replaced with the User's DN. |
276 | |
277 | =head2 role_scope |
278 | |
279 | This specifies the scope of the search for the user's role lookup. Valid |
280 | values are "base", "one", and "sub". Defaults to "sub". |
281 | |
282 | =head2 role_field |
283 | |
284 | Should be set to the Attribute of the Role Object's returned during Role lookup you want to use as the "name" of the role. Defaults to "CN". |
285 | |
286 | =head2 role_value |
287 | |
288 | This is the attribute of the User object we want to use in our role_filter. |
289 | If this is set to "dn", we will use the User Objects DN. |
290 | |
291 | =head2 role_search_options |
292 | |
293 | This takes a hashref. It will append it's values to the call to |
294 | L<Net::LDAP>'s "search" method during the user's role lookup. See |
295 | L<Net::LDAP> for valid options. |
296 | |
297 | Be careful not to specify: |
298 | |
299 | filter |
300 | scope |
301 | base |
302 | |
303 | As they are already taken care of by other configuration options. |
304 | |
405489b5 |
305 | =head2 role_search_as_user |
306 | |
307 | By default this setting is false, and the role search will be performed |
308 | by binding to the directory with the details in the I<binddn> and I<bindpw> |
309 | fields. If this is set to false, then the role search will instead be |
310 | performed when bound as the user you authenticated as. |
311 | |
312 | =head2 entry_class |
313 | |
314 | The name of the class of LDAP entries returned. This class should |
315 | exist and is expected to be a subclass of Net::LDAP::Entry |
316 | |
317 | =head2 user_class |
318 | |
319 | The name of the class of user object returned. By default, this is |
320 | L<Catalyst::Authentication::Store::LDAP::User>. |
321 | |
