__construct()

__construct

(

)

Constructor

the constructor is private, you should use StudipAuthAbstract::GetInstance($plugin_name) to get a reference to a plugin object. Make sure the constructor in the base class is called when deriving your own plugin class, it assigns the settings from local.inc as members of the plugin each key of the $STUDIP_AUTH_CONFIG_<plugin name> array will become a member of the object

@access private

Reimplemented in StudipAuthLdap, StudipAuthLdapReadAndBind, and StudipAuthStandard.

Member Function Documentation

authenticateUser()

authenticateUser	(		$username,
			$password
	)

authentication method

this method authenticates the passed username, it is used by StudipAuthAbstract::CheckAuthentication() if authentication succeeds it calls StudipAuthAbstract::doDataMapping() to map data fields if the authenticated user logs in for the first time it calls StudipAuthAbstract::doNewUserInit() to initialize the new user @access private

Parameters

string	the username to check
string	the password to check

Returns

string if authentication succeeds the Stud.IP user , else false

Here is the call graph for this function:

CheckAuthentication()

static CheckAuthentication (   $username,   $password  )

static

static method to check authentication in all plugins

if authentication fails in one plugin, the error message is stored and the next plugin is used if authentication succeeds, the uid element in the returned array will contain the Stud.IP user id

@access public

Parameters

string	the username to check
string	the password to check

Returns

array structure: array('uid'=>'string <Stud.IP user id>','error'=>'string <error message>','is_new_user'=>'bool')

Here is the call graph for this function:

Here is the caller graph for this function:

CheckField()

static CheckField (   $field_name,   $plugin_name  )

static

static method to check for a mapped field

this method checks in the plugin with the passed name, if the passed Stud.IP DB field is mapped to an external data source

@access public

Parameters

string	the name of the db field must be in form ' <field name>'
string	the name of the plugin to check

Returns

bool true if the field is mapped, else false

Here is the caller graph for this function:

CheckUsername()

static CheckUsername (   $username )

static

static method to check if passed username is used in external data sources

all plugins are checked, the error messages are stored and returned

@access public

Parameters

string

the username

Returns

array

Here is the caller graph for this function:

doDataMapping()

doDataMapping

(

$user

)

this method handles the data mapping

for each entry in $this->user_data_mapping the according callback will be invoked the return value of the callback method is then written to the db field, which is specified in the key of the array

@access private

Parameters

User	the user object

Returns

bool

Here is the caller graph for this function:

doNewUserInit()

doNewUserInit

(

$user

)

initialize a new user

this method is invoked for one time, if a new user logs in ($this->is_new_user is true) place special treatment of new users here

@access private

Parameters

User	the user object

Returns

bool

Here is the caller graph for this function:

getInstance()

static getInstance (   $plugin_name = false )

static

static method to instantiate and retrieve a reference to an object (singleton)

use always this method to instantiate a plugin object, it will ensure that only one object of each plugin will exist @access public

Parameters

string

name of plugin, if omitted an array with all plugin objects will be returned

Returns

mixed either a reference to the plugin with the passed name, or an array with references to all plugins

getStudipUser()

getStudipUser

(

$username

)

method to retrieve the Stud.IP user id to a given username
