Extension:SimpleSAMLphp/zh

The SimpleSAMLphp extension extends the extension to provide authentication using SimpleSAMLphp.

配置
Values must be provided for the following mandatory configuration variables:

In addition, the following optional configuration variables are provided:

定义用户信息提供者
If you want to modify any of the fields,   or   before login, you can configure a custom callback for. The factory method has the following signature:

For simple usecases one can use :

Group mapping
Use case: your SAML IdP reads groups from LDAP or Database and stores this information inside an attribute of the SAML response. You want to use this to map MediaWiki groups to users belonging to some known groups given by your IdP.

Example:


 * Your IdP sends an attribute named "groups" with a list of names like "administrator", "student", "teacher", ... in the SAML response after authentication.
 * All users that have the value "administrator" in the "groups" attribute shall be mapped to the MediaWiki "sysop" group to give them admin rights within your MediaWiki instance.
 * Create a group map in your LocalSettings.php as follows:

You can come up with rather complex mappings that fit your needs. If you have more than one attribute from SAML, just add it to the array with the array of values you like to map.

If a MediaWiki group does not exist, it will be created "on the fly" on first successful mapping of a user.

Group mapping #2
Since version 4.3 one can also configure an alternative group synchronization mechanism. Besides the default "MapGroups" one can use "SyncAllGroups", which takes all groups from the SAML response and assign the user to them.

To do so, add the following to the :

If the IdP returns group names that are not suitable for the wiki, one can set up a callback to modify the group names. E.g. some IdP-Setups may return LDAP-DNs like "CN=Admin,OU=Groups,DC=SomeDomain". One could then specify in :

Processing arbitrary data from the SAML response
The "attribute processors" can also be used to handle arbitrary data from the SAML response. In this case one must first create a new PHP class that implements the  interface. For convenience the base class  can be used, which has a proper factory callback and constructor implemented. An example

It then needs to be instantiated by using the.

已知错误
If you are using MediaWiki 1.27 or later with PluggableAuth 2.0 or later, problems have been observed when SimpleSAMLphp is configured to use phpession for store.type. This may be due to T147161. To fix this, use a different store type in the configuration of the SimpleSAMLphp software by adjusting simplesamlphp/config/config.php (see https://simplesamlphp.org/docs/stable/simplesamlphp-maintenance#section_2_3). For example, for SQLite, use:

'store.type' => 'sql', 'store.sql.dsn' => 'sqlite:/path/where/the/apache/user/can/write/sqlitedatabase.sq3',

For MySQL, use:

'store.type' => 'sql', 'store.sql.dsn' => 'mysql:host=xxx;port=xxx;dbname=xxx', 'store.sql.username' => 'xxx', 'store.sql.password' => 'xxx',
