Use-cases
Authentication
Scenario
...
Example JSF code:
| Code Block | ||||
|---|---|---|---|---|
| ||||
Username: <h:inputText value="#{credentials.username}"/>
Password: <h:inputSecret id="password" value="#{credentials.password}"/>
<h:commandButton value="LOGIN" action="#{identity.login}"/>
|
...
| Code Block |
|---|
public class SimpleAuthenticator extends BaseAuthenticator implements Authenticator {
@Inject Credentials credentials;
@Override
public void authenticate() {
if ("demo".equals(credentials.getUsername()) &&
credentials.getCredential() instanceof PasswordCredential &&
"demo".equals(((PasswordCredential) credentials.getCredential()).getValue())) {
setStatus(AuthenticationStatus.SUCCESS);
setUser(new SimpleUser("demo"));
} else {
setStatus(AuthenticationStatus.FAILURE);
}
}
}
|
Scenario
It should be possible to provide an optional password service to create a password-hash based on the given password which will be stored instead of the real password.
Maybe there should be different default implementations (provided via qualifiers).
...
| Code Block |
|---|
Group itsec = identityManager.createGroup(“itsec”, “/organization/engineering/security”);
itsec.addRole(“manager”, “johnDoe”);
Group hr = identityManager.createGroup(“hr”, “/organization”);
hr.addRole(“supervisor”, “aliceDoe”);
hr.addRole(“headhunter”, “chrisDoe”);
aliceDoe.hasRole(“headhunter”);
List<User> headHunters = identityManager.createUserQuery().setRole(“headhunter”).sort(true).setRange(Range.of(0,50).execute();
|
Scenario
Application needs to expose capabilities to associate authenticated user with specific roles in application context.
