LDAP Authentication using Java
Hier ist ein Stück Javacode mit dem man eine LDAP Authentifizierung realisieren kann:
import javax.naming.*;
import javax.naming.directory.*;
import java.util.Hashtable;
/**
* Demonstrates how to create an initial context to an LDAP server
* using simple authentication.
*/
class Simple {
public static void main(String[] args) {
Hashtable authEnv = new Hashtable(11);
String userName = "johnlennon";
String passWord = "sushi974";
String base = "ou=People,dc=example,dc=com";
String dn = "uid=" + userName + "," + base;
String ldapURL = "ldap://ldap.example.com:389";
authEnv.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
authEnv.put(Context.PROVIDER_URL, ldapURL);
authEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
authEnv.put(Context.SECURITY_PRINCIPAL, dn);
authEnv.put(Context.SECURITY_CREDENTIALS, passWord);
try {
DirContext authContext = new InitialDirContext(authEnv);
System.out.println("Authentication Success!");
} catch (AuthenticationException authEx) {
System.out.println("Authentication failed!");
} catch (NamingException namEx) {
System.out.println("Something went wrong!");
namEx.printStackTrace();
}
}
}
