Authentication error 49 52e with jndi in a java application- invalid token

Question

I'd like to be ask an LDAP server if the provided username and password are correct in a Java application.

I ended up using jndi with this function (it is a test function I am using to explore LDAP that returns the exception message):

public static String checkCredentials(String securityPrincipal,
                               String password,
                               String ldapUrl,
                               String securityAuthentication) 
{
    String userVerify = "";
    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, ldapUrl);
    env.put(Context.SECURITY_AUTHENTICATION, securityAuthentication);
    env.put(Context.SECURITY_PRINCIPAL, securityPrincipal);
    env.put(Context.SECURITY_CREDENTIALS, password);

    try {
        DirContext authContext = new InitialDirContext(env);
        userVerify = testDescription + " - Success";
        authContext.close();
    } catch (AuthenticationException authEx) {
        userVerify = "AuthenticationException: " + authEx.getMessage();//"Authentication failed!";
    } catch (NamingException namEx) {
        userVerify = "NamingException: " + namEx.getMessage();//"Something went wrong!";
    } 
    return userVerify;
}

As I call checkCredentials by passing the correct ldapUrl (that in my case it's ldap://192.168.48.60:389) i always get as result (the function returns a String):

AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C0903A8, comment: AcceptSecurityContext error, data 52e, v1db1]

This page says that it is an authentication error (49) and "username is valid but password/credential is invalid" (52e).

I tried all of these for securityPrincipal:

john

john@mycompany

CN=john,conn

CN=john,OU=internal users,DC=mycompany

password and secuirityAuthentication seem ignored.

I tried to install LDAP admin from http://www.ldapadmin.org/ and also from it I get:

LDAP error! Invalid credentials: 80090308: LdapErr: DSID-0C0903A8, comment: AcceptSecurityContext error, data 52e, v1db1.

Invalid token passed to the function.

Somehow this tells me something more "invalid token".

Any pointers? I am stuck.

Passing "none" instead of "simple" in securityAuthentication made the job.

At least there are no exceptions, even if UserVerifyT returns success even if the passowrd is wrong, i will handle this as i did in the past by retrieving the mail of the user, if mail is returned password is ok.
