一、背景
亲测可用,之前搜索了很多博客,啥样的都有,就是不介绍报错以及配置用处,根本不懂照抄那些配置是干啥的,稀里糊涂的按照博客搭完也跑不起来,因此记录这个。
项目背景
:公司项目当前采用http协议+shiro+mysql的登录认证方式,而现在想支持ldap协议认证登录然后能够访问自己公司的项目网站。
举例说明
:假设我们公司有自己的门户网站,现在我们收购了一家公司,他们数据库采用ldap存储用户数据,那么为了他们账户能登陆我们公司项目所以需要集成,而不是再把他们的账户重新在mysql再创建一遍,万一人家有1W个账户呢,不累死了且也不现实啊。
需要安装openldap+kerberos,且ldap和kerberos安装在同一台服务器上,当前版本如下:
centos 7.9
openldap 2.4.44
phpldapadmin 1.2.5
服务器IP:10.110.38.162
Kerberos :Kerberos 5 release 1.15.1
另外介绍下我的Spring各个版本:
Spring Security:4.2.3.RELEASE
Spring Version:4.3.9.RELEASE
SpringBoot Version:1.4.7.RELEASE
注意点1:
我之所以选这么旧的版本,是因为我最后要在自己项目集成,我们项目就是上面版本附近的,所以不能选太高版本,这点请注意各版本之间的兼容性问题。
详情可看这篇博客介绍兼容版本:https://zhuanlan.zhihu.com/p/652895555
注意点2
:如果里面的某些配置不知道在哪或者不知道干啥的,可以看我的前面的博客,详细介绍了安装配置等,可以大致了解参数。
目前网上相关文章很少,而且好多博客都是未认证就发布的所以一堆问题,跑不起来,如下是我参考的博客
- Spring Security Kerberos - Reference Documentation
- MIT Kerberos Documentation
- https://www.openldap.org/
- Authentication Protocols: LDAP vs Kerberos vs OAuth2 vs SAML vs RADIUS

场景描述
:我把demo项目打包运行在209服务器,而ldap+kerberos安装在38.162服务器上,进行接口联调。
错误原因
:
主要看这行:CLIENT_NOT_FOUND: ldaptest3@NODE3.COM for krbtgt/NODE3.COM@NODE3.COM, Client not found in Kerberos database
再看这行:javax.security.auth.login.LoginException: Receive timed out
报错显示javax.security.auth.login.LoginException: Receive timed out,总感觉代码没连接kerberos,或者说感觉java代码客户端对面kerberos不认识。
之前我是demo运行在38.162就能认证应该是能识别,当我把demo放在209服务器上就报错了
猜测可能是209服务器的连接不上38.162的88端口,所以应该是网络的问题
举例说明
:
举例说明:56.70服务器运行telnet 命令查看88端口是否可用
[root@localhost temporary]# telnet 10.110.38.162 88
Trying 10.110.38.162...
Connected to 10.110.38.162.
Escape character is '^]'.
209运行telnet 命令查看88端口是否可用
[root@localhost temporary]# telnet 10.110.38.162 88
Trying 10.110.38.162...
telnet: connect to address 10.110.38.162: Connection timed out
[root@localhost temporary]#
解决方案
:你换台服务器跑项目就能调通了。
