我已经搜索了如何为Java Web应用程序提供基于活动目录/ LDAP的登录名。在这个论坛上也差不多。 100张以上的票，我听不懂，或者没有像我一样的目标。我尝试了几种配置。
使用以下代码，我得到了最好的结果，但是仍然不能完全正常工作。
import java.util.Hashtable;

import javax.naming.NamingEnumeration;
import javax.naming.directory.Attributes;

System.out.println(fullPath);
System.setProperty("sun.security.krb5.debug", "true");

}
final SearchControls ctrl = new SearchControls();
ctrl.setSearchScope(SearchControls.SUBTREE_SCOPE);
ctrl.setReturningAttributes(LdapAuth.requiredAttributes);

Integer i = 0;
do
{

i++;
}
while(!userInfo.hasMore() && i < LdapAuth.ADSearchPaths.length);
if(userInfo.hasMore())
{

System.out.println("adEmail = " + userAttr.get("userPrincipalName").get(0).toString());
System.out.println("adFirstName = " + userAttr.get("givenName").get(0).toString());
System.out.println("adLastName = " + userAttr.get("sn").get(0).toString());
System.out.println("name = " + userAttr.get("cn").get(0).toString());
System.out.println("AdFullName = " + userAttr.get("cn").get(0).toString());
}
userInfo.close();
}
catch(final javax.naming.AuthenticationException e)
{
e.printStackTrace();
}
}
}
作为AD控制器，我使用synology AD程序包。我尝试了简单的身份验证，但这没有用。
我有一个错误：
javax.naming.AuthenticationNotSupportedException: [LDAP: error code 8 - BindSimple: Transport encryption required.]
at com.sun.jndi.ldap.LdapCtx.mapErrorCode(Unknown Source)
...
附加信息。通过客户端控制台上的klist，我为用户获得了两张票。而且我能够通过AD控制器上的ssh从客户端控制台成功登录
更改和设置System.setProperty ...之后。6行和设置而不是简单：
env.put(Context.SECURITY_AUTHENTICATION, "GSSSAPI");
我得到了以下输出，并在控制台上要求我输入Kerberos用户ID。

此输出后，出现以下错误：
java.lang.IllegalArgumentException: Empty nameStrings not allowed
at sun.security.krb5.PrincipalName.validateNameStrings(Unknown Source)
我试图弄清楚如何防止这种情况：也没有成功同时设置
System.setProperty("sun.security.krb5.PrincipalName", user + "@MY.DOMAIN");
仍然没有用。
还有其他信息，我的服务器支持：
{{supportedsaslmechanisms = supportedSASLMechanisms：GSS-SPNEGO，GSSAPI，NTLM}
我认为要使其运行有多个问题。我还不确定的是，是否需要以任何方式配置我的tomcat？
我已经设法通过oauth / azure广告解决了它。它不是LDAP-但是仍然很有趣。看看：https://github.com/xware-gmbh/SeicentoBilling
