I'm not sure if this is the best solution, but I could achieve something similar with those steps:(1) You should extend AbstractAuthenticationComponent:
public class MyUserAuthenticationImpl extends AbstractAuthenticationComponent {
(…)
@Override
protected void authenticateImpl(String userName, char[] password) {
if (!checkUserAndPasswordOnDatabase(userName, password))
throw new AuthenticationException("Invalid credentials.");
// Successfully authenticated…
clearCurrentSecurityContext();
setCurrentUser(userName);
}
private boolean checkUserAndPasswordOnDatabase(String username, char[] password) {
// TODO: Implement your SQL query here…
}
}
(2) Register the bean in "alfresco/subsystems/Authentication/myUserAuthentication/myUserAuthentication-context.xml":
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>
<beans>
<bean id="authenticationComponent" class="MyUserAuthenticationImpl"
parent="authenticationComponentBase">
<property name="nodeService">
<ref bean="nodeService" />
</property>
<property name="personService">
<ref bean="personService" />
</property>
<property name="transactionService">
<ref bean="transactionService" />
</property>
</bean>
<bean id="localAuthenticationService"
class="org.alfresco.repo.security.authentication.AuthenticationServiceImpl">
<property name="ticketComponent">
<ref bean="ticketComponent" />
</property>
<property name="authenticationComponent">
<ref bean="authenticationComponent" />
</property>
<property name="sysAdminParams">
<ref bean="sysAdminParams" />
</property>
</bean>
</beans>
(3) Edit your alfresco-global.properties and define:
authentication.chain=myUserAuthentication1:myUserAuthentication
…where myUserAuthentcation is the same name of that XML path.
