public class Authenticate
extends Authentication

Very simply security from within MMBase. You might want to look at Cloud Context Security which offers a much more powerful implementation.

Method Detail

load

protected void load()

This method should be overridden by an extending class. It should further initialize the class. It can optionally retrieve settings from the general security configuration file (available as the 'configResource' member). Security implementations with complicated configuration would typically retrieve a path to their own configuration file only. Implementation is empty here.

Specified by:

load in class Configurable

getRank

protected Rank getRank(String userName)

Gets rank from user

Parameters:

userName - account name of user

Returns:

Rank of the user

Since:

MMBase-1.8

login

public UserContext login(String moduleName,
                         Map loginInfo,
                         Object[] parameters)
                  throws SecurityException

This method will verify the login, and give a UserContext back if the login procedure was successful.

Specified by:

login in class Authentication

Parameters:

moduleName - A String that further specifies the login method (one implementation could handle more then one methods) A typical value might be 'username/password'. Possible values are returned by Authentication.getTypes(). This is also called 'authentication', or '(authentication) type' in several contextes.

loginInfo - A Map containing the credentials or other objects which might be used to obtain them (e.g. request/response objects). It might also be 'null', in which case your implementation normally should return the 'anonymous' user (or null, if no such user can be defined). This Map can (or must) be supplied by Authentication.createParameters(java.lang.String) (using the setter-methods and the Parameters.toMap(java.util.Map) method of the resulting Parameters object).

parameters - A list of optional parameters, may also (and will often) be null.

Returns:

null if no valid credentials were supplied, a (perhaps new) UserContext if login succeeded.

Throws:

SecurityException - When something strange happened, or authentication was unsuccessful.

isValid

public boolean isValid(UserContext usercontext)
                throws SecurityException

The method returns whether the UserContext has become invalid for some reason (change in security config?)

Parameters:

usercontext - The UserContext of which we want to know the rights

Returns:

true when valid, otherwise false

Throws:

SecurityException - When something strange happened
