Class AbstractChainingAuthenticationComponent

java.lang.Object

org.alfresco.repo.security.authentication.AbstractAuthenticationComponent

org.alfresco.repo.security.authentication.AbstractChainingAuthenticationComponent

All Implemented Interfaces:

AuthenticationComponent, AuthenticationContext

Direct Known Subclasses:

ChainingAuthenticationComponentImpl, SubsystemChainingAuthenticationComponent

public abstract class AbstractChainingAuthenticationComponent
extends AbstractAuthenticationComponent

A base class for chaining authentication components. Where appropriate, methods will 'chain' across multiple AuthenticationComponent instances, as returned by AbstractChainingAuthenticationComponent.getUsableAuthenticationComponents().

Methods

Modifier and Type	Method and Description
protected void	authenticateImpl(java.lang.String userName, char[] password) Chain authentication with user name and password - tries all in order until one works, or fails.
protected abstract AuthenticationComponent	getAuthenticationComponent(java.lang.String name) Get the authentication component with the specified name
java.util.Set	getDefaultAdministratorUserNames() Gets a set of user names who for this particular authentication system should be considered administrators by default.
java.util.Set	getDefaultGuestUserNames() Gets a set of user names who for this particular authentication system should be considered guests by default.
protected abstract java.util.Collection	getUsableAuthenticationComponents() Gets the authentication components across which methods will chain.
protected boolean	implementationAllowsGuestLogin() If any implementation supports guest then guest is allowed.
net.sf.acegisecurity.Authentication	setCurrentUser(java.lang.String userName) Set the current user - try all implementations - as some may check the user exists.
net.sf.acegisecurity.Authentication	setCurrentUser(java.lang.String userName, AuthenticationComponent.UserNameValidationMode validationMode) Explicitly set the current user to be authenticated.
void	testAuthenticate(java.lang.String authenticatorName, java.lang.String userName, char[] password) Test authenticate with a specific authenticator and user name and password.

Constructor Detail

AbstractChainingAuthenticationComponent

public AbstractChainingAuthenticationComponent()

Instantiates a new abstract chaining authentication component.

Method Detail

getAuthenticationComponent

protected abstract AuthenticationComponent getAuthenticationComponent(java.lang.String name)

Get the authentication component with the specified name

Parameters:

name -

Returns:

the authentication component or null if it does not exist

getUsableAuthenticationComponents

protected abstract java.util.Collection getUsableAuthenticationComponents()

Gets the authentication components across which methods will chain.

Returns:

the usable authentication components

authenticateImpl

protected void authenticateImpl(java.lang.String userName,
                    char[] password)

Chain authentication with user name and password - tries all in order until one works, or fails.

Overrides:

authenticateImpl in class AbstractAuthenticationComponent

Parameters:

userName - the user name

password - the password

Throws:

AuthenticationException

testAuthenticate

public void testAuthenticate(java.lang.String authenticatorName,
                    java.lang.String userName,
                    char[] password)

Test authenticate with a specific authenticator and user name and password.

Parameters:

authenticatorName - the name of the authenticator to use

userName - the user name

password - the password

Throws:

AuthenticationException - including diagnostic information about the failure

implementationAllowsGuestLogin

protected boolean implementationAllowsGuestLogin()

If any implementation supports guest then guest is allowed.

Specified by:

implementationAllowsGuestLogin in class AbstractAuthenticationComponent

Returns:

true, if implementation allows guest login

setCurrentUser

public net.sf.acegisecurity.Authentication setCurrentUser(java.lang.String userName,
                                                 AuthenticationComponent.UserNameValidationMode validationMode)

Description copied from interface: AuthenticationComponent

Explicitly set the current user to be authenticated. Specify if the userName is to be checked and fixed

Specified by:

setCurrentUser in interface AuthenticationComponent

Overrides:

setCurrentUser in class AbstractAuthenticationComponent

setCurrentUser

public net.sf.acegisecurity.Authentication setCurrentUser(java.lang.String userName)

Set the current user - try all implementations - as some may check the user exists.

Specified by:

setCurrentUser in interface AuthenticationComponent

Overrides:

setCurrentUser in class AbstractAuthenticationComponent

Parameters:

userName - the user name

Returns:

the authentication

getDefaultAdministratorUserNames

public java.util.Set getDefaultAdministratorUserNames()

Gets a set of user names who for this particular authentication system should be considered administrators by default. If the security framework is case sensitive these values should be case sensitive user names. If the security framework is not case sensitive these values should be the lower-case user names.

Specified by:

getDefaultAdministratorUserNames in interface AuthenticationComponent

Overrides:

getDefaultAdministratorUserNames in class AbstractAuthenticationComponent

Returns:

a set of user names

getDefaultGuestUserNames

public java.util.Set getDefaultGuestUserNames()

Gets a set of user names who for this particular authentication system should be considered guests by default. If the security framework is case sensitive these values should be case sensitive user names. If the security framework is not case sensitive these values should be the lower-case user names.

Specified by:

getDefaultGuestUserNames in interface AuthenticationComponent

Overrides:

getDefaultGuestUserNames in class AbstractAuthenticationComponent

Returns:

a set of user names
