Wiki source code of User Authentication

Version 75.1 by Thomas Mortagne on 2014/09/27
Show last authors
1 XWiki supports several different authentication mechanisms for authenticating users:
2
3 {{toc/}}
4
5 {{info}}
6 XWiki currently allows only one method of authentication to be enabled at a time. This will probably be improved in the future.
7 {{/info}}
8
9 Also note that XWiki requires cookies to be enable in order to track your session and to keep you logged in between pages.
10
11 = Form Authentication =
12
13 Form authentication is the default way to get authenticated within a Wiki. It requires a user and a password.
14
15 = Basic Authentication =
16
17 XWiki supports [[basic access authentication>>http://en.wikipedia.org/wiki/Basic_access_authentication]], a method designed to allow a web browser or other client programs to provide credentials - in the form of a user name and password - when making a request. You can get authenticated against an XWiki server with the basic authentication protocol using the following URL scheme:
18
19 {{code}}
20 http://username:password@mywiki.xwiki.com/xwiki/bin/view/Main/WebHome?basicauth=1
21 {{/code}}
22
23 {{warning}}
24 Be careful that if you use the ##HTTP## protocol your password will be sent in clear over the network and is thus very unsafe. When using basic authentication you should make sure your wiki is configured to use ##HTTPS##.
25 {{/warning}}
26
27 = Container Authentication =
28
29 Delegates authentication to the Servlet Container. If it fails it falls back to the standard XWiki authentication.
30
31 To configure XWiki to use it, specify:
32
33 {{code}}
34 xwiki.authentication.authclass=com.xpn.xwiki.user.impl.xwiki.AppServerTrustedAuthServiceImpl
35 {{/code}}
36
37 = Social Login =
38
39 See the [[Social Login Application>>extensions:Extension.Social Login Application]].
40
41 = LDAP Authentication =
42
43 If you are going to use the [[LDAP Admin Extension>>http://extensions.xwiki.org/xwiki/bin/view/Extension/LDAP+Application#HPrerequisites26InstallationInstructions]], which makes it easier to configure LDAP, then you only need to uncomment xwiki.authentication.authclass property and //nothing// else. Unlike editing xwiki.cfg, which requires you to redeploy xWiki app, LDAP Extension allows you to make changes without restarting.
44
45 == Generic LDAP configuration ==
46
47 In order to enable the LDAP support you have to change the authentication method in //WEB-INF/xwiki.cfg// as follows:
48
49 {{code language="properties"}}
50 #-# LDAP authentication service
51 # xwiki.authentication.authclass=com.xpn.xwiki.user.impl.LDAP.XWikiLDAPAuthServiceImpl
52
53 #-# Turn LDAP authentication on - otherwise only XWiki authentication
54 #-# - 0: disable
55 #-# - 1: enable
56 #-# The default is 1
57 # xwiki.authentication.ldap=1
58 {{/code}}
59
60 You can setup the LDAP configuration in the **xwiki.cfg** file by filling the following properties:
61
62 {{code language="properties"}}
63 #-# LDAP Server (Active Directory, eDirectory, OpenLDAP, etc.)
64 xwiki.authentication.ldap.server=127.0.0.1

68 #-# {0} is replaced with the user name, {1} with the password
69 xwiki.authentication.ldap.bind_DN=cn={0},department=USER,department=INFORMATIK,department=1230,o=MP
70 xwiki.authentication.ldap.bind_pass={1}
71
72 #-# The Base DN used in LDAP searches
73 xwiki.authentication.ldap.base_DN=
74
75 #-# LDAP query to search the user in the LDAP database (in case a static admin user is provided in

188
189 {{info}}
190 You can also setup the LDAP configuration in the XWiki.XWikiPreferences page by going to the object editor. Simply replace **xwiki.authentication.ldap.** with **ldap_**. For example ##xwiki.authentication.ldap.base_DN## becomes ##ldap_base_DN##.
191 {{/info}}
192
193 For testing purposes, you may wish to omit the "ldap.fields_mapping" field, to test the authentication first, and then add it later to get the mappings right.
194
195 Here are some LDAP clients for checking your configuration:
196
197 Java based and Open Source:
198
199 * [[Apache Directory Studio>>http://directory.apache.org/studio/]]
200 * [[JXplorer>>http://jxplorer.org/]]
201
202 Windows only:
203
204 * [[Softerra LDAP Browser>>http://www.ldapbrowser.com/info_softerra-ldap-browser.htm]]
205
206 == Detailed use cases ==
207
208 See the [[LDAP configuration uses cases>>LDAPAuthenticationUseCases]] for some detailed use cases.
209
210 == Enable LDAP debug log ==
211
212 See [[AdminGuide.Logging]].
213
214 The specific packages to track for LDAP are ##com.xpn.xwiki.plugin.ldap## and ##com.xpn.xwiki.user.impl.LDAP##.
215
216 Starting with XWiki 4.2 we added a new [[Logging UI>>extensions:Extension.Logging Application]] from the Administration section, which allows logging to be enabled at runtime, directly from the UI, without the need to restart the wiki.
217
218 In XWiki 3.4 you need to add the following in ##WEB-INF/classes/logback.xml##:
219
220 {{code}}
221 <!-- LDAP debugging -->
222 <logger name="com.xpn.xwiki.plugin.ldap" level="trace"/>
223 <logger name="com.xpn.xwiki.user.impl.LDAP" level="trace"/>
224 {{/code}}
225
226 Before 3.1, add the following to the log4j configuration file:
227
228 {{code}}
229 log4j.logger.com.xpn.xwiki.plugin.ldap=trace
230 log4j.logger.com.xpn.xwiki.user.impl.LDAP=trace
231 {{/code}}
232
233 = Custom Authentication =
234
235 This allows plugging to any existing authentication mechanism such as SiteMinder, etc. To configure a custom authentication do the following:
236
237 1. Implement the {{scm path="xwiki-platform-core/xwiki-platform-oldcore/src/main/java/com/xpn/xwiki/user/api/XWikiAuthService.java"}}XWikiAuthService{{/scm}} interface.
238 1. Edit the //WEB-INF/xwiki.cfg// file and add a //xwiki.authentication.authclass// property pointing to your class. For example:
239
240 {{code language="properties"}}
241 xwiki.authentication.authclass = com.acme.MyCustomAuthenticationService
242 {{/code}}
243
244 You can find various [[authenticators examples>>https://github.com/xwiki-contrib/sandbox/tree/master/authenticators]].
245
246 Here's a [[tutorial on implementing a custom authentication class for authenticating against Oracle's SSO>>http://bodez.wordpress.com/2008/10/15/xwiki-user-authentication-with-oracle-sso/]].
247
248 Note, that you can also implement own right management service by implementing the {{scm path="xwiki-platform-core/xwiki-platform-oldcore/src/main/java/com/xpn/xwiki/user/api/XWikiRightService.java"}}XWikiRightService{{/scm}} interface:
249
250 {{code language="properties"}}
251 xwiki.authentication.rightsclass = com.acme.MyCustomRightsService
252 {{/code}}
253
254 and Group Service by implementing {{scm path="xwiki-platform-core/xwiki-platform-oldcore/src/main/java/com/xpn/xwiki/user/api/XWikiGroupService.java"}}XWikiGroupService{{/scm}}:
255
256 {{code language="properties"}}
257 xwiki.authentication.groupclass = com.acme.MyCustomGroupService
258 {{/code}}
259
260 == Custom Authentication using a Groovy script in a wiki page ==
261
262 Start by specifying you want to use the Groovy Authenticator:
263
264 {{code language="properties"}}
265 xwiki.authentication.authclass = com.xpn.xwiki.user.impl.xwiki.GroovyAuthServiceImpl
266 {{/code}}
267
268 Then add another configuration parameter to specify in which wiki page the authenticator is:
269
270 {{code language="properties"}}
271 xwiki.authentication.groovy.pagename = MySpace.MyPage
272 {{/code}}
273
274 Then put some Groovy code in a wiki page that returns a XWikiAuthService object.
275
276 = Authentication parameters =
277
278 You can set each of these parameters by setting:
279
280 {{code}}
281 xwiki.authentication.~~param_name~~=~~param_value~~
282 {{/code}}
283
284 |=Name|=Optional|=Allowed values|=Default value|=Description
285 |encryptionKey|No(1)|?|n/a|Set the Encryption Key used to create a secret key, the secret key is passed to the Cipher object to be used during encryption and decryption of cookie values.
286 |validationKey|No(2)|?|n/a|Set the Validation Key used to generate hash value; the hash value is stored with the cookie and used to verify that the cookie has not been tampered with.
287 |cookiedomains|Yes|String|Server host name|Which host(s) should your cookies be sent to; use only if you want to share cookies across domains, otherwise should be commented out
288 |cookielife|Yes|Number|14|Number of days cookies take to expire
289 |cookiepath|Yes|String|/|The webapp path that XWiki cookies should be sent to; if you have anything else running on your web server, this should be set to ///xwiki//
290 |default_page|Yes|String|/bin/view/ Main/WebHome|Page to redirect to if xredirect parameter is not set
291 |encryptionalgorithm|Yes|?|?|Set the Encryption Algorithm used to encrypt and decrypt cookies
292 |encryptionmode|Yes|?|?|Set the Encryption Mode used to encrypt and decrypt cookies
293 |encryptionpadding|Yes|?|?|Set the Encryption Padding used to encrypt and decrypt cookies
294 |errorpage|Yes|String|/bin/loginerror/ XWiki/XWikiLogin|Page to redirect to if there is an error logging in
295 |loginpage|Yes|String|/bin/login/ XWiki/XWikiLogin|Page to redirect to when not logged in
296 |loginsubmitpage|Yes|String|/loginsubmit/ XWiki/XWikiLogin|The URL where the username and password are posted to when logging in.
297 |logoutpage|Yes|String|/bin/logout/ XWiki/XWikiLogout|Page to redirect to after logged out
298 |realmname|Yes|String|XWiki|Sets the realm name
299 |protection|Yes|all, validation, encryption, none|all|Protection level for the "remember me" cookie functionality
300 |unauthorized_code|Yes|Number|401|The HTTP status code to return when the login has failed.
301 |useip|Yes|true / false|true|Specify to use the IP address when encrypting the cookie data; if IP address changes will need to re-login.
302
303 1. Only required if protection = encryption or all (default)
304 1. Only required if protection = validation or all (default)
305
306 = Kerberos SSO Authentication =
307
308 {{warning}}
309 This implementation of SSO is currently under review see: http://jira.xwiki.org/jira/browse/XWIKI-2496 . The class which is described in this segment of documentation, AppServerTrustedKerberosAuthServiceImpl, is not part of the default XWiki distribution!
310 {{/warning}}
311
312 The following is an example of **mod_auth_kerb** for Apache being used to easily implement XWiki authentication of users via HTTP Negotiate on a linux server. This example assumes you already have a working Apache2 HTTPD and Apache Tomcat setup with mod_jk.
313
314 First of all you need to create a principal and keytab for the webserver:
315
316 {{code}}
317 # kadmin
318 kadmin> addprinc -randkey HTTP/wiki.example.com
319 kadmin> ktadd -k /etc/apache2/ssl/wiki.keytab HTTP/wiki.example.com
320 kadmin> quit
321 {{/code}}
322
323 Make sure the keytab has the right permissions and ownership:
324
325 {{code}}
326 chown www-data:www-data /etc/apache2/ssl/wiki.keytab
327 chmod 400 /etc/apache2/ssl/wiki.keytab
328 {{/code}}
329
330 Install **mod_auth_kerb** in your linux installation. On Debian or Ubuntu this would be achieved by running:
331
332 {{code}}
333 aptitude install libapache2-mod-auth-kerb
334 {{/code}}
335
336 Of course the installation procedure varies per Linux distribution.
337
338 If your xwiki installation is mounted in Apache HTTPD under /xwiki, add the following to the virtual host configuration:
339
340 {{code}}
341 <Location /xwiki/>
342 AuthType Kerberos
343 AuthName "Kerberos Login"
344 KrbAuthRealms EXAMPLE.COM
345 Krb5Keytab "/etc/apache2/ssl/wiki.keytab"
346 KrbMethodK5Passwd off
347 KrbMethodNegotiate on
348 KrbSaveCredentials on
349 require valid-user
350 </Location>
351 {{/code}}
352
353 Make sure Apache Tomcat uses the authentication performed by Apache HTTPD with the "tomcatAuthentication" property in the connector description (which is in the **server.xml** file of Apache Tomcat):
354
355 {{code}}
356 <Connector port="8009" address="127.0.0.1" enableLookups="false" tomcatAuthentication="false" redirectPort="8443" protocol="AJP/1.3" />
357 {{/code}}
358
359 Place the **authkerb.jar** jar in the ##WEB-INF/lib## directory of XWiki in Apache Tomcat.
360
361 Have Xwiki use the authentication module by changing the "xwiki.authentication.authclass" property in the ##WEB-INF/lib/xwiki.cfg## file.
362
363 {{code}}
364 xwiki.authentication.authclass=com.xpn.xwiki.user.impl.xwiki.AppServerTrustedKerberosAuthServiceImpl
365 {{/code}}
366
367 If you use Firefox, do not forget to whitelist the xwiki URL for HTTP Negotiate in about:config with the "network.negotiate-auth.trusted-uris" property. Possible values for this property include: //https:~/~/// for all secured connections or **example.com** for all example.com subdomains.
368
369 When I used JBoss SPNEGO (Kerberos in combination with LDAP) I changed the code of the **XWikiLDAPAuthServiceImpl** to be able to detect the sso user. The authenication already happend by using the SPNEGO module (JAAS). After that I'm using the ldap synchronisation feature to make sure that the user is up to date. The combination leads to an automatic login in XWiki and the user rights are controlled in the Active Directory server. I hope you can adopt this code or that you can use it for your own projects.
370
371 The configuration of ldap:
372
373 {{code}}
374 xwiki.authentication.authclass=com.wiki.sso.SSOLdapAuthenicationImpl
375 xwiki.authentication.ldap=1
