HandlerResult

[Jeffrey Ramsay]

Hello -

I am trying to build an authentication handler in cas 6.2 using the stub code from the example and cannot get past the following error message.

Does anyone know if this is no longer valid? or where I can find the module where this class is defined?

error: cannot find symbol
import org.apereo.cas.authentication.HandlerResult;
                                    ^
  symbol:   class HandlerResult
  location: package org.apereo.cas.authentication

Thanks,

-Jeff

Hi there.

Which stub code example?

You’d want to make sure you implement the correct SPI for AuthenticationHandler, which is this: https://github.com/apereo/cas/blob/6.2.x/api/cas-server-core-api-authentication/src/main/java/org/apereo/cas/authentication/AuthenticationHandler.java

Best,

D.

Hello,

I was following the code listed here.

https://apereo.github.io/cas/6.2.x/installation/Configuring-Custom-Authentication.html

Also, I added the following to build.gradle:

    implementation "org.apereo.cas:cas-server-core-api-authentication:${casServerVersion}"
    implementation "org.apereo.cas:cas-server-core-authentication-api:${casServerVersion}"

    implementation "org.apereo.cas:cas-server-support-generic:${casServerVersion}"
    implementation "org.apereo.cas:cas-server-support-actions:${casServerVersion}"  
    implementation "org.apereo.cas:cas-server-core-authentication:${casServerVersion}"
    implementation "org.apereo.cas:cas-server-core-authentication-attributes:${casServerVersion}"
    implementation "org.apereo.cas:cas-server-core-services-authentication:${casServerVersion}"
    implementation "org.apereo.cas:cas-server-core-configuration:${casServerVersion}"
    implementation "org.apereo.cas:cas-server-core-configuration-api:${casServerVersion}"

And the code I'm testing.

package com.example.cas;

import org.apereo.cas.authentication.handler.support.AbstractUsernamePasswordAuthenticationHandler;
import org.apereo.cas.authentication.credential.UsernamePasswordCredential;
import org.apereo.cas.authentication.principal.PrincipalFactory;
import org.apereo.cas.authentication.PreventedException;
import org.apereo.cas.services.ServicesManager;
import org.apereo.cas.authentication.Credential;
import java.security.GeneralSecurityException;

import org.apereo.cas.authentication.principal.Principal;

public class MyAuthenticationHandler extends AbstractUsernamePasswordAuthenticationHandler {

    public MyAuthenticationHandler(String name, ServicesManager servicesManager, PrincipalFactory principalFactory, Integer order) {
        super(name, servicesManager, principalFactory, order);
    }

    @Override
    protected HandlerResult authenticateUsernamePasswordInternal(

                                                                 final UsernamePasswordCredential credential,
                                                                 final String originalPassword) {
        return createHandlerResult(credential, this.principalFactory.createPrincipal(username), null);
    }
}

Unfortunately, the documentation is not up to date. The API has changed. As you could see there is no HandlerResult type anymore: https://github.com/apereo/cas/blob/6.2.x/core/cas-server-core-authentication-api/src/main/java/org/apereo/cas/authentication/handler/support/AbstractUsernamePasswordAuthenticationHandler.java#L120

It’s called AuthenticationHandlerExecutionResult

See if you could adopt your implementation to the latest API

Best,

D.
