フォレスト アーキテクチャで LDAP を使用しています (すべてのサーバーと私のサーバーは Windows です)。NTLM 認証を使用して AD にバインドしています。
LDAP サーバーに対して操作を実行する Java コードがあります。
コードは、Tomcat サーブレットとしてラップされます。
JAVA コードを直接実行する場合 (LDAP 認証コードをアプリケーションとして実行するだけ)、バインドはローカル ドメイン (ローカル ドメイン = Windows にログインし、このドメインのユーザーでこのプロセスを実行) と外部ドメインの両方に対して機能します。 .
JAVA コードをサーブレットとして実行すると、バインドが機能し、あるドメインのユーザーを認証しますが、別のドメインのユーザーを認証しようとすると機能しません (Tomcat を再起動した場合にのみ機能します) ）。
私は例外を取得しています：
GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Message stream modified (41))]]
これは同じコードで、同じ構成と同じ krb5 ファイルを使用していることに言及します。
編集： 詳細：
これは私のコードです:
public void func(String realm, String kdc) {
try {
URL configURL = getClass().getResource("jaas_ntlm_configuration.txt");
System.setProperty("java.security.auth.login.config", configURL.toString());
System.setProperty("java.security.krb5.realm", realm);
System.setProperty("java.security.krb5.kdc",kdc);
// 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 the initial context
DirContext ctx = new InitialLdapContext(env, null);
// Close the context when we're done
ctx.close();
} catch (NamingException e) {
e.printStackTrace();
}
}
}
そして、私の jaas_ntlm_configuration.txt ファイルには以下が含まれています。
MyConfig { com.sun.security.auth.module.Krb5LoginModule required
useTicketCache=true
doNotPrompt=false;
};

func("SUB*.DOMAIN.COM", "DDC.SUB*.DOMAIN.COM") を常に同じサブドメインで呼び出すと動作しますが、あるサブドメインで呼び出してから別のサブドメインで呼び出すと、 2番目は失敗します。
