java连接ldap服务器_java – LDAP：如何使用连接详细信息验证用...
我无法使用LDAP对用户进行身份验证.我有以下细节：
URL=ldap://10.10.10.10:389
LDAP BASE:DC=lab2,DC=ins
LDAP Bind Account: CN=Ldap Bind,OU=Service Accounts,OU=TECH,DC=lab2,DC=ins
LDAP Bind Account Pw: secret
我可以使用上面的详细信息搜索sAMAccountName值,但是如何使用用户名和密码验证用户？
如果您按照我之前的问题进行操作,那么您将了解到,我已成功连接到LDAP服务器但无法对其进行身份验证.
用户进行身份验证：
user: someusername
password: somepwd
我无法使用’somepwd’连接到LDAP服务器,我应该如何使用someusername.我能够将给定用户搜索为sAMAccountName.
最佳答案
这是我在各个地方找到的东西的混搭.如果您不想使用UnboundID SDK,它应该让您沿着正确的路径前进.这不是生产质量,如果您的商店支持,您可能希望在此处添加SSL内容.
