LDAP: error code 49 - Simple Bind Failed: NT_STATUS_LOGON_FAILURE

I am trying to authenticate the user but it throws Exception.May be there is problem in configuration.

public class LdapApplication {
private static final String INITIAL_CONTEXT_FACTORY = "com.sun.jndi.ldap.LdapCtxFactory";
private static final String SECURITY_AUTHENTICATION ="simple";
private static final String NAMED_CONTEXT = "CN=Users";
private static final String SAM_ACCOUNT_NAME = "sAMAccountName=";

public static void main(String[] args) {

    Hashtable env = new Hashtable();

    env.put(Context.INITIAL_CONTEXT_FACTORY,INITIAL_CONTEXT_FACTORY);
    env.put(Context.PROVIDER_URL, "ldap://ip:portNo/dc=organisation,dc=in");
    env.put(Context.SECURITY_AUTHENTICATION, SECURITY_AUTHENTICATION);
    env.put(Context.SECURITY_PRINCIPAL, "cn=userName,cn=Users");
    env.put(Context.SECURITY_CREDENTIALS, "password" );
    DirContext context = null;

    NamingEnumeration namingEnumeration = null;
    try {
        context = new InitialDirContext(env);

        namingEnumeration = context.search(NAMED_CONTEXT, SAM_ACCOUNT_NAME+ userName, null);
        while (namingEnumeration.hasMore()) {
            SearchResult searchResult = (SearchResult) namingEnumeration.next();
            Attributes attributes = searchResult.getAttributes();

            System.out.println(" Person Common Name = " + attributes.get("cn"));
          System.out.println(" Person Display Name = " + attributes.get("displayName"));

            }catch(Exception e){
                System.out.println(e.getMessage());
                e.printStackTrace();

            }
        }
    } catch (Throwable e) {
        e.printStackTrace();
    } finally {
        if (namingEnumeration != null) {
            try {
                namingEnumeration.close();
            } catch (Exception e) {
            }
        }
        if (context != null) {
            try {
                context.close();
            } catch (Exception e) {
            }
        }
    }

}

}

but if i mention Context.SECURITY_PRINCIPAL as "organisation\\userName" instead of "cn=userName,cn=Users" it works perfectly fine. Kindly suggest a possible solution because my requirement is to give SECURITY_PRINCIPAL something using cn or dc.

We were having the same issue in our code and we fixed it by adding the domain name before the user name. Instead of entering user:password, enter domain\user:password.

Hope this helps.

To do an LDAP bind you will need to use one of the a Unique return for one of the Ambiguous Name Resolution entries. Normally, one would use the Fully Distinguished name.

We have a JNDI Example showing how this could be done.

You are using a relative distinguished name which will not work.

Change your code to use 

env.put(Context.SECURITY_PRINCIPAL, "cn=userName,cn=Users,dc=organisation,dc=in");

and also change your search context to:

private static final String NAMED_CONTEXT = "CN=Users,dc=organisation,dc=in";

Always use full distinguished names with LDAP.
