我正在尝试使用带有NTLM的Windows凭据为ActiveDirectory创建上下文(客户端和服务器都是Windows)。
这是我的代码:
public void func() {
try {
URL configURL = getClass().getResource("jaas_ntlm_configuration.txt");
System.setProperty("java.security.auth.login.config", configURL.toString());
// If the application is run on NT rather than Unix, use this name
String loginAppName = "MyConfig";
// Create login context
LoginContext lc = new LoginContext(loginAppName, new SampleCallbackHandler());
// Retrieve the information on the logged-in user
lc.login();
// Get the authenticated subject
Subject subject = lc.getSubject();
System.out.println(subject.toString());
Subject.doAs(subject, new JndiAction(new String[] { "" }));
}
catch (LoginException e) {
e.printStackTrace();
}
}
class JndiAction implements java.security.PrivilegedAction {
private String[] args;
public JndiAction(String[] origArgs) {
this.args = (String[])origArgs.clone();
}
public Object run() {
performJndiOperation(args);
return null;
}
private static void performJndiOperation(String[] args) {
// Set up environment for creating initial context
Hashtable env = new Hashtable(11);
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
// Must use fully qualified hostname
env.put(Context.PROVIDER_URL, "ldap://server:389");
// Request the use of the "GSSAPI" SASL mechanism
// Authenticate by using already established Kerberos credentials
env.put(Context.SECURITY_AUTHENTICATION, "GSSAPI");
try {
/* Create initial context */
// DirContext ctx = new InitialDirContext(env);
// Create the initial context
DirContext ctx = new InitialLdapContext(env, null);
// Close the context when we're done
ctx.close();
} catch (NamingException e) {
e.printStackTrace();
}
}
}
我的jaas_ntlm_configuration.txt文件包含:
MyConfig { com.sun.security.auth.module.Krb5LoginModule required
useTicketCache=true
doNotPrompt=false;
};
当我尝试启动上下文时,出现以下异常:
javax.naming.AuthenticationException: GSSAPI [Root exception is javax.security.sasl.SaslException: Final handshake failed [Caused by GSSException: Token had invalid integrity check (Mechanism level: Corrupt checksum in Wrap token)]]

有人可以帮我解决这个问题吗?
最佳答案
您实际上正在使用Kerberos身份验证。
如果这是您的意思,那么我可以告诉您如何成功进行操作:
- add somewhere a file called krb5.conf with inside :
[libdefaults]
default_realm = YOUR_REALM
default_tkt_enctypes = arcfour-hmac-md5
default_tgs_enctypes = arcfour-hmac-md5
permitted_enctypes = arcfour-hmac-md5
dns_lookup_kdc = true
dns_lookup_realm = false
[realms]
YOUR_REALM = {
kdc = KERBEROS_SERVER
default_domain = YOUR_REALM
}
System.setProperty(“java.security.krb5.conf”,PATH_TO_KRB5CONF_FILE);
System.setProperty(“sun.security.krb5.principal”,PRINCIPAL_NAME_WITHOUT_DOMAIN);
如果您不知道Kerberos服务器,则无法从命令行启动klist,并采用使用LDAP协议的服务(LDAP / server @ domain->服务器)。
如果仍然无法正常工作,请尝试添加
System.setProperty("sun.security.krb5.debug", "true");
并发布输出。
