Question

请帮我解决kerberos + Java问题。我有一个简单的Java程序，可以使用Kerberos对Windows Active Directory进行身份验证。以下java代码工作正常，没有任何问题，并打印为true -

public class KerberosAuthenticator {
    public static void main(String[] args) {
        String jaasConfigFilePath = "/myDir/jaas.conf";

        System.setProperty("java.security.auth.login.config", jaasConfigFilePath);

        System.setProperty("java.security.krb5.realm", "ENG.TEST.COM");
        System.setProperty("java.security.krb5.kdc","winsvr2003r2.eng.test.com");

        boolean success = auth.KerberosAuthenticator.authenticate("testprincipal", "testpass");

        System.out.println(success);
    }
}

当我指定krb5.conf文件的路径而不是手动指定领域和kdc时，它会错误地说“Null领域名称（601） - 未指定默认领域”。以下是代码 -

public class KerberosAuthenticator {
    public static void main(String[] args) {
        String jaasConfigFilePath = "/myDir/jaas.conf";

        System.setProperty("java.security.auth.login.config", jaasConfigFilePath);

        String krb5ConfigFilePath = "/etc/krb5/krb5.conf";
        System.setProperty("java.security.krb5.conf", krb5ConfigFilePath);

        boolean success = auth.KerberosAuthenticator.authenticate("testprincipal", "testpass");

        System.out.println(success);
    }
}

krb5.conf的内容如下 -

[libdefault]
 default_realm = ENG.TEST.COM

[realms]
 ENG.TEST.COM = {
  kdc = winsvr2003r2.eng.test.com
  kpasswd_server = winsvr2003r2.eng.test.com
  admin_server = winsvr2003r2.eng.test.com
  kpasswd_protocol = SET_CHANGE
 }

[domain_realm]
 .eng.test.com = ENG.TEST.COM
 eng.test.com = ENG.TEST.COM
[logging]
 default = FILE:/var/krb5/kdc.log
 kdc = FILE:/var/krb5/kdc.log
 kdc_rotate = {
  period = 1d
  versions = 10
 }

[appdefaults]
 kinit = {
 renewable = true
 forwardable = true
 }

你的krb5.conf错了。它是 [libdefaults] ，而不是[libdefault]。

Java和Kerberos身份验证krb5.conf与System.setProperty的对比
