/**
|
||||
* This example shows several things:
|
||||
* - How a setup interface should look like.
|
||||
* - How to use a mysql table for authentication
|
||||
* - How to store associations in mysql table, instead of php sessions.
|
||||
* - How to store realm authorizations.
|
||||
* - How to send AX/SREG parameters.
|
||||
* For the example to work, you need to create the necessary tables:
|
||||
CREATE TABLE Users (
|
||||
id INT NOT NULL auto_increment PRIMARY KEY,
|
||||
login VARCHAR(32) NOT NULL,
|
||||
password CHAR(40) NOT NULL,
|
||||
firstName VARCHAR(32) NOT NULL,
|
||||
lastName VARCHAR(32) NOT NULL
|
||||
);
|
||||
|
||||
CREATE TABLE AllowedSites (
|
||||
user INT NOT NULL,
|
||||
realm TEXT NOT NULL,
|
||||
attributes TEXT NOT NULL,
|
||||
INDEX(user)
|
||||
);
|
||||
|
||||
CREATE TABLE Associations (
|
||||
id INT NOT NULL PRIMARY KEY,
|
||||
data TEXT NOT NULL
|
||||
);
|
||||
*
|
||||
* This is only an example. Don't use it in your code as-is.
|
||||
* It has several security flaws, which you shouldn't copy (like storing plaintext login and password in forms).
|
||||
*
|
||||
* This setup could be very easily flooded with many associations,
|
||||
* since non-private ones aren't automatically deleted.
|
||||
* You could prevent this by storing a date of association and removing old ones,
|
||||
* or by setting $this->dh = false;
|
||||
* However, the latter one would disable stateful mode, unless connecting via HTTPS.
