一、安装Keycloak

1. 运行Keycloak服务端

• KeyCloak Container
• KeyCloak Container文档
• KeyCloak 修改端口

docker run --detach \
  --publish 8880:8080 \
  --env KEYCLOAK_ADMIN=admin \
  --env KEYCLOAK_ADMIN_PASSWORD=admin \
  --env KC_HOSTNAME_PORT=8880 \
  --ip 172.18.0.99 \
  --hostname idp.light.local \
  --add-host sp.light.local:10.106.136.62 \
  --network dev \
  --restart=no \
  --name keycloak \
  quay.io/keycloak/keycloak:24.0 start-dev

docker exec -it -u root keycloak /bin/bash

# 查看域名解析
cat /etc/hosts
# idp的ip为容器虚拟ip，用于自身识别
# sp的ip为物理机的ip，用于访问sp
172.18.0.99     idp.light.local
10.106.136.62   sp.light.local

• Dashboard
  • admin / admin

2. 创建一个Oidc客户端，测试Oidc登录

curl --include --location 'http://idp.light.local:8880/realms/Test/protocol/openid-connect/token' \
  --header 'Content-Type: application/x-www-form-urlencoded' \
  --data-urlencode 'username=light' \
  --data-urlencode 'password=light' \
  --data-urlencode 'grant_type=password' \
  --data-urlencode 'client_id=oidc_client' \
  --data-urlencode 'client_secret=BnFwExLLBNtYPIq4E1aQbsvHKohOPKwg' \
  --data-urlencode 'scope=openid'

3. 配置本地Hosts

# idp和sp都在本地，直接使用 本地地址即可
127.0.0.1       idp.light.local
127.0.0.1       sp.light.local

4. 生成证书

openssl req -newkey rsa:2048 -nodes -keyout sp-private.key -x509 -days 365 -out sp-certificate.crt

二、配置Keycloak

1. 创建 Realm

1. 访问管理员控制台，进行管理员账号登陆，点击上图的Administration Console即可进入下面的页面

2. 进入页面后我们看到的是Master的Realm界面，我们需要创建自己的Realm

3. 创建Realm，填写Realm的名称

• Clients: 客户端管理
• Users: 用户管理
• Realm Setting: 查看SAML OIDC配置项

2. 创建 Clients

1. 创建客户端 Clients

• Client type: SAML
• Client ID *: saml_client

2. 配置Service Provider的信息

参数名	参数值	描述
Root URL	http://sp.light.local:18080	应用首页，前后端分离的填前端地址
Home URL	/	首页地址
Valid redirect URIs	http://sp.light.local:18080/login/saml2/sso/keycloak	白名单URL，设置回调URL即可
Valid post logout redirect URIs	http://sp.light.local:18080/logout/saml2/slo	注销登录回调页
IDP-Initiated SSO URL name
IDP Initiated SSO Relay State
Master SAML Processing URL	http://sp.light.local:18080/login/saml2/sso/keycloak	回调URL，必填

3. General settings

4. Access settings

5. SAML capabilities

6. Signature and Encryption

• Sign documents : Off 不需要校验文档内容
• Sign assertions: Off 校验 assertions 即可
• Signature algorithm : RSA_SHA256
• SAML signature key name : KEY_ID
• Canonicalization method : EXCLUSIVE_WITH_COMMENTS

7. Login settings & Logout settings

8. 生成客户端的证书并导入到Keycloak

openssl req -newkey rsa:2048 -nodes -keyout sp-private.key -x509 -days 365 -out sp-certificate.crt

切换到客户端的Keys页面，点击 Import Key 导入 sp-certificate.crt 文件

9. 也可以使用Keycloak生成的jks作为秘钥配置到Spring Boot应用中

在keys界面导出一个keycloak.jks的文件，SpringBoot和keycloak交互时需要根据这个去生成请求参数

这里设置的属性都需要配置到Spring Boot中，分别是keyEntryId keyPassword keystorePassword，此处设置均为keycloak

3. 创建 Users

1. 创建用户 Users，账号密码: light / light

4. 查看 Realm 的 SAML2 的元数据 metadata.xml 文件

1. 进入 Realm Settings 在 General 页签中

2. 点击 Endpoints - SAML 2.0 Identity Provider Metadata 访问元数据页面 http://idp.light.local:8880/realms/Test/protocol/saml/descriptor

3. 讲 X509Certificate 的值导出来，作为idp的证书文件 keycloak.crt

5. 最后

1. 配置完成后将得到两个文件 keycloak.jks 和 keycloak.crt，存下后面备用

2. 如果 Service Provider 使用本地生成的 sp-private.key 和 sp-certificate.crt ，则不需要使用 keycloak.jks 文件，但是需要将 sp-certificate.crt 导入到Client中

3. 如果 Service Provider 使用 keycloak.jks 作为私钥和证书，则需要将 keycloak.jks 配置到应用中

4. 服务端证书文件 keycloak.crt 是可选的，一般通过服务端的元数据端点可以直接获取到

三、配置Okta

1. 注册一个自己的域okta账号 okta账户创建

1. 选择 Workforce Identity Cloud - Okta Developer Edition Service
2. 使用github登录
3. https://dev-70304605-admin.okta.com/admin/getting-started

2. 登录刚刚创建的okta-admin域，创建一个Application

1. 点击创建应用 Create App Integration

2. 选择SAML 并点击next

3. 填写必要参数填写参数

• Single Sign On URL: http://sp.light.local:8080/saml2/authenticate/okta
• Audience Restriction: http://sp.light.local:8080/saml2/service-provider-metadata/okta

注意：Single sign on URL表示登录成功后回调的地址，一般为后端的某个接口地址，后续会有用到

4. 选择创建内部应用程序、应用创建完毕

5. 打开应用，查看SAML2登录证书、提取onelogin必要参数，后续java配置需要用到

https://dev-70304605.okta.com/app/exkg3seq7hh0uUigL5d7/sso/saml/metadata

3. 通过上一步可以打开一个saml的配置页面，提取图中相关参数

4. 配置Logout

1. 生成证书

openssl req -newkey rsa:2048 -nodes -keyout rp-private.key -x509 -days 365 -out rp-certificate.crt

2. 导入证书，并填入logout地址

• Single Logout URL: http://sp.light.local:8080/logout/saml2/slo
• SP Issuer : http://sp.light.local:8080/saml2/service-provider-metadata/okta

四、配置AD FS

五、Spring应用编码
