$alias = array()

[line 193]

All fields with their alias

Access: public

Type:

array

[ Top ]

$containerName = null

[line 153]

The name associated with this auth container. The name is used when adding users from this container to the reference table in the permission container. This way it is possible to see from which auth container the user data is coming from.

Access: public

Type:

string

[ Top ]

$currentLogin = 0

[line 77]

Timestamp of current login (last to be written)

Access: public

Type:

int

[ Top ]

$encryptionModes = array(
        'MD5'   => 'MD5',
        'PLAIN' => 'PLAIN',

        'SHA1'  => 'SHA1'
    )

[line 106]

Possible encryption modes.

Access: public

Type:

array

[ Top ]

$expireTime = 0

[line 87]

Auth maximum lifetime in seconds

If this variable is set to 0, auth never expires

A list of handle fields that are used to find a user.

Access: public

Type:

array

[ Top ]

$idleTime = 0

[line 98]

Maximum time of idleness in seconds

Idletime gets refreshed each time, init() is called. If this variable is set to 0, idle time is never checked.

Method Detail

LiveUser_Auth_Common (Constructor) [line 203]

void LiveUser_Auth_Common(
)

Class constructor. Feel free to override in backend subclasses.

Var: configuration options
Access: protected

[ Top ]

decryptPW [line 304]

string decryptPW(
string
$encryptedPW)

Decrypts a password so that it can be compared with the user input.

Uses the algorithm defined in the passwordEncryptionMode property.

Return: the decrypted password
Access: public

Parameters:

string $encryptedPW — the encrypted password

[ Top ]

disconnect [line 483]

bool disconnect(
)

properly disconnect from resources

Return: true on success or false on failure
Access: public

Overridden in child classes as:

LiveUser_Auth_XML::disconnect(): Properly disconnect from resources

LiveUser_Auth_PDO::disconnect(): properly disconnect from database

LiveUser_Auth_MDB2::disconnect(): properly disconnect from database

LiveUser_Auth_MDB::disconnect(): Properly disconnect from database

LiveUser_Auth_DB::disconnect(): Properly disconnect from database

[ Top ]

encryptPW [line 318]

string encryptPW(
string
$plainPW)

Encrypts a password for storage in a backend container.

Uses the algorithm defined in the passwordEncryptionMode property.

Return: the encrypted password
Access: public

Parameters:

string $plainPW — encryption type

[ Top ]

externalValuesMatch [line 459]

bool externalValuesMatch(
)

Check if the stored external values match the current external values

Return: true on success or false on failure
Access: public

[ Top ]

freeze [line 263]

array freeze(
)

store all properties in an array

Access: public

[ Top ]

getProperty [line 420]

mixed getProperty(
string
$what)

Function returns the inquired value if it exists in the class.

Return: null, a scalar or an array.
Access: public

Parameters:

string $what — name of the property to be returned.

[ Top ]

init [line 217]

bool init(
array
$conf, string
$containerName)

Load the storage container

Return: true on success or false on failure
Access: public

Overridden in child classes as:

LiveUser_Auth_XML::init(): Load the storage container

LiveUser_Auth_PDO::init(): Load the storage container

LiveUser_Auth_MDB2::init(): Load the storage container

LiveUser_Auth_Session::init(): Load the storage container

LiveUser_Auth_MDB::init(): Load the storage container

LiveUser_Auth_DB::init(): Load the storage container

LiveUser_Auth_PEARAuth::init(): Load the storage container

Parameters:

array	`$conf`	—	array containing the configuration.
string	`$containerName`	—	name of the container that should be used

[ Top ]

login [line 334]

bool login(
string
$handle, string
$passwd, [bool|int
$auth_user_id = false])

Tries to make a login with the given handle and password.

A user can't login if he's not active.

Return: null when user is inactive, true on success or false on failure
Access: public

Parameters:

string	`$handle`	—	user handle
string	`$passwd`	—	user password
bool\|int	`$auth_user_id`	—	if the user data should be read using the auth user id

[ Top ]

readUserData [line 404]

bool readUserData(
[string
$handle = ''], [string
$passwd = ''], [bool|int
$auth_user_id = false])

Reads user data from the given data source If only $handle is given, it will read the data from the first user with that handle and return true on success.

If $handle and $passwd are given, it will try to find the first user with both handle and password matching and return true on success (this allows multiple users having the same handle but different passwords - yep, some people want this). if only an auth_user_id is passed it will try to read the data based on the id If no match is found, false is being returned.

Again, this does nothing in the base class. The described functionality must be implemented in a subclass overriding this method.

Return: true on success or false on failure
Access: public

Overridden in child classes as:

LiveUser_Auth_XML::readUserData(): Reads user data from the given data source If only $handle is given, it will read the data from the first user with that handle and return true on success.

LiveUser_Auth_PDO::readUserData(): Reads user data from the given data source If only $handle is given, it will read the data from the first user with that handle and return true on success.

LiveUser_Auth_MDB2::readUserData(): Reads user data from the given data source If only $handle is given, it will read the data from the first user with that handle and return true on success.

LiveUser_Auth_Session::readUserData(): Reads user data from the given data source Compares $passwd with a string inside the $_SESSION array

LiveUser_Auth_MDB::readUserData(): Reads user data from the given data source If only $handle is given, it will read the data from the first user with that handle and return true on success.

LiveUser_Auth_DB::readUserData(): Reads user data from the given data source If only $handle is given, it will read the data from the first user with that handle and return true on success.

LiveUser_Auth_PEARAuth::readUserData(): Reads user data from the given data source Starts and verifies the PEAR::Auth login process

Parameters:

string	`$handle`	—	user handle
string	`$passwd`	—	user password
bool\|int	`$auth_user_id`	—	if the user data should be read using the auth user id

setExternalValues [line 438]

void setExternalValues(
)

Access: public

[ Top ]

unfreeze [line 286]

bool unfreeze(
array
$propertyValues)

Reinitializes properties

Access: public

Parameters:

array $propertyValues —
