59 | DESCRIPTION |
60 | This plugin implements the Catalyst::Authentication v.10 API. Read that |
61 | documentation first if you are upgrading from a previous version of this |
62 | plugin. |
fa35fd6f |
63 | |
a93dbce7 |
64 | This plugin uses "Net::LDAP" to let your application authenticate |
65 | against an LDAP directory. It has a pretty high degree of flexibility, |
66 | given the wide variation of LDAP directories and schemas from one system |
67 | to another. |
fa35fd6f |
68 | |
a93dbce7 |
69 | It authenticates users in two steps: |
fa35fd6f |
70 | |
a93dbce7 |
71 | 1) A search of the directory is performed, looking for a user object |
72 | that matches the username you pass. This is done with the bind |
73 | credentials supplied in the "binddn" and "bindpw" configuration options. |
fa35fd6f |
74 | |
a93dbce7 |
75 | 2) If that object is found, we then re-bind to the directory as that |
76 | object. Assuming this is successful, the user is Authenticated. |

114 | user_filter: (&(objectClass=posixAccount)(uid=%s)) |
115 | user_scope: one |
116 | user_field: uid |
117 | user_search_options: |
118 | deref: always |
119 | use_roles: 1 |
120 | role_basedn: ou=groups,ou=OxObjects,dc=yourcompany,dc=com |
121 | role_filter: (&(objectClass=posixGroup)(memberUid=%s)) |
122 | role_scope: one |
123 | role_field: uid |
124 | role_value: dn |
125 | role_search_options: |
126 | deref: always |
127 | |
128 | NOTE: The settings above reflect the default values for OpenLDAP. If you |
129 | are using Active Directory instead, Matija Grabnar suggests that the |
130 | following tweeks to the example configuration will work: |
131 | |
132 | user_basedn: ou=Domain Users,ou=Accounts,dc=mycompany,dc=com |
133 | user_field: samaccountname |
ff35d7cb |
134 | user_filter: (sAMAccountName=%s) |
a93dbce7 |
135 | |
136 | He also notes: "I found the case in the value of user_field to be |
137 | significant: it didn't seem to work when I had the mixed case value |
138 | there." |
139 | |
140 | ldap_server |
141 | This should be the hostname of your LDAP server. |
142 | |
143 | ldap_server_options |
144 | This should be a hashref containing options to pass to Net::LDAP->new(). |
145 | See Net::LDAP for the full list. |
146 | |
147 | binddn |
148 | This should be the DN of the object you wish to bind to the directory as |
149 | during the first phase of authentication. (The user lookup phase) |
150 | |
151 | If you supply the value "anonymous" to this option, we will bind |
152 | anonymously to the directory. This is the default. |
153 | |
154 | bindpw |
155 | This is the password for the initial bind. |
156 | |
157 | start_tls |
158 | If this is set to 1, we will convert the LDAP connection to use SSL. |
159 | |
160 | start_tls_options |
161 | This is a hashref, which contains the arguments to the Net::LDAP |
162 | start_tls method. See Net::LDAP for the complete list of options. |
163 | |
164 | user_basedn |
165 | This is the basedn for the initial user lookup. Usually points to the |
166 | top of your "users" branch; ie "ou=people,dc=yourcompany,dc=com". |
167 | |
168 | user_filter |
169 | This is the LDAP Search filter used during user lookup. The special |
170 | string '%s' will be replaced with the username you pass to $c->login. By |
171 | default it is set to '(uid=%s)'. Other possibly useful filters: |
172 | |
173 | (&(objectClass=posixAccount)(uid=%s)) |
174 | (&(objectClass=User)(cn=%s)) |
175 | |
176 | user_scope |
177 | This specifies the scope of the search for the initial user lookup. |
178 | Valid values are "base", "one", and "sub". Defaults to "sub". |
179 | |
180 | user_field |
181 | This is the attribute of the returned LDAP object we will use for their |
182 | "username". This defaults to "uid". If you had user_filter set to: |
183 | |
184 | (&(objectClass=User)(cn=%s)) |
185 | |
186 | You would probably set this to "cn". You can also set it to an array, to |
187 | allow more than one login field. The first field will be returned as |
188 | identifier for the user. |
189 | |
190 | user_search_options |
191 | This takes a hashref. It will append it's values to the call to |
192 | Net::LDAP's "search" method during the initial user lookup. See |
193 | Net::LDAP for valid options. |
194 | |
195 | Be careful not to specify: |
196 | |
197 | filter |
198 | scope |
199 | base |
200 | |
201 | As they are already taken care of by other configuration options. |
202 | |
203 | user_results_filter |
204 | This is a Perl CODE ref that can be used to filter out multiple results |
205 | from your LDAP query. In theory, your LDAP query should only return one |
206 | result and find_user() will throw an exception if it encounters more |
207 | than one result. However, if you have, for whatever reason, a legitimate |
208 | reason for returning multiple search results from your LDAP query, use |
209 | "user_results_filter" to filter out the LDAP entries you do not want |
210 | considered. Your CODE ref should expect a single argument, a |
211 | Net::LDAP::Search object, and it should return exactly one value, a |
212 | Net::LDAP::Entry object. |
213 | |
214 | Example: |
215 | |
216 | user_results_filter => sub { |
217 | my $search_obj = shift; |
218 | foreach my $entry ($search_obj->entries) { |
219 | return $entry if my_match_logic( $entry ); |
220 | } |
221 | return undef; # i.e., no match |
222 | } |
ff35d7cb |
223 | |
a93dbce7 |
224 | use_roles |
225 | Whether or not to enable role lookups. It defaults to true; set it to 0 |
226 | if you want to always avoid role lookups. |
227 | |
228 | role_basedn |
229 | This should be the basedn where the LDAP Objects representing your roles |
230 | are. |
231 | |
232 | role_filter |
233 | This should be the LDAP Search filter to use during the role lookup. It |
234 | defaults to '(memberUid=%s)'. The %s in this filter is replaced with the |
235 | value of the "role_value" configuration option. |
236 | |
237 | So, if you had a role_value of "cn", then this would be populated with |
238 | the cn of the User's LDAP object. The special case is a role_value of |
239 | "dn", which will be replaced with the User's DN. |
240 | |
241 | role_scope |
242 | This specifies the scope of the search for the user's role lookup. Valid |
243 | values are "base", "one", and "sub". Defaults to "sub". |
244 | |
245 | role_field |
246 | Should be set to the Attribute of the Role Object's returned during Role |
247 | lookup you want to use as the "name" of the role. Defaults to "CN". |
248 | |
249 | role_value |
250 | This is the attribute of the User object we want to use in our |
251 | role_filter. If this is set to "dn", we will use the User Objects DN. |
252 | |
253 | role_search_options |
254 | This takes a hashref. It will append it's values to the call to |
255 | Net::LDAP's "search" method during the user's role lookup. See Net::LDAP |
256 | for valid options. |
257 | |
258 | Be careful not to specify: |
259 | |
260 | filter |
261 | scope |
262 | base |
263 | |
264 | As they are already taken care of by other configuration options. |
265 | |
266 | role_search_as_user |
267 | By default this setting is false, and the role search will be performed |
268 | by binding to the directory with the details in the *binddn* and |
269 | *bindpw* fields. If this is set to false, then the role search will |
270 | instead be performed when bound as the user you authenticated as. |
271 | |
272 | entry_class |
273 | The name of the class of LDAP entries returned. This class should exist |
274 | and is expected to be a subclass of Net::LDAP::Entry |
275 | |
276 | user_class |
277 | The name of the class of user object returned. By default, this is |
278 | Catalyst::Authentication::Store::LDAP::User. |
279 | |
280 | METHODS |
281 | new |
282 | This method will populate "default_auth_store" in |
283 | Catalyst::Plugin::Authentication with this object. |
