I have to configure Spring security to authenticate user through LDAP. This is the subtree where manager user is: 

ldaps://vldp.floal:636/CN=Administration,CN=fdam,DC=fg,DC=local

and this is where users are:

ldaps://vldp.floal:636/CN=ProxyUsers,CN=fdam,DC=fg,DC=local

So I use this setting:

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception{
     auth.ldapAuthentication()
      .contextSource()
        .url("ldaps://vldp.floal:636/DC=fg,DC=local")
        .managerDn("CN=A0XXX32,CN=Administration,CN=fdam,DC=fg,DC=local")
        .managerPassword(password)
      .and()         
      .userSearchBase("CN=ProxyUsers,CN=fdam")     
      .userSearchFilter("(CN={0})")
      .ldapAuthoritiesPopulator(myAuthPopulator);     
}

The problem is exception thrown when I try to make login through user, i receive this error:

2016-03-25 14:43:14 [http-nio-8086-exec-6] ERROR o.s.s.w.a.UsernamePasswordAuthenticationFilter - An internal error occurred while trying to authenticate the user.

There is a problem with spring parameters because if I use java code to authenticate users it works. I can't figure out where is the problem, can you help me?

I went in debug and this is the output before the error:

PS: If with a ldap browser use CN=F67XXX7A,CN=ProxyUsers,CN=fdam,DC=fg,DC=local it binds.

UPDATE: if I use java without Spring login works, I need to use Spring and figure out how to configure it:

@Override
public void isAuthenticated(String username, String password) throws LdapException{
    if (databaseMatlabClientServices.getByUsersEnabled(username)== null)
        throw new LdapException("User doesn't exist into DART database. Please contact the administrator!");
    String dn="";;
    //First query to retriev DN
    Hashtable<String, Object> ldapEnv = new Hashtable<String, Object>();
    ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    ldapEnv.put(Context.PROVIDER_URL, env.getRequiredProperty(PROPERTY_NAME_LDAP_URL));
//Without authentication        ldapEnv.put(Context.SECURITY_AUTHENTICATION, "none");
    //With authentication to access to LDAP server
    ldapEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
    ldapEnv.put(Context.SECURITY_PRINCIPAL, env.getRequiredProperty(PROPERTY_NAME_LDAP_NAME));
    ldapEnv.put(Context.SECURITY_CREDENTIALS, env.getRequiredProperty(PROPERTY_NAME_LDAP_PASSWORD));
    String[] returnAttribute = {"dn"};
    DirContext ctx = null;
    NamingEnumeration<SearchResult> results = null;
    try {
        ctx = new InitialDirContext(ldapEnv);
        SearchControls controls = new SearchControls();
        controls.setReturningAttributes(returnAttribute);
        controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
// without authentication on local server String filter = "uid=" + username ;
        String filter = "CN=" + username ;
        results = ctx.search(env.getRequiredProperty(PROPERTY_NAME_LDAP_USERSEARCHBASE), filter, controls);
        if (results.hasMore())
            dn = results.nextElement().getNameInNamespace();
        else 
            throw new LdapException("Wrong username. Please retry!");
    } catch (NamingException e) {
        throw new LdapException(e);
    } finally {
        try{
            if (results != null)
                results.close();             
            if (ctx != null) 
                ctx.close();
        }catch(Exception e){
            throw new LdapException(e);
        }
    }

    //Second query to try to access with obtained Dn and given password
    Hashtable<String, Object> authEnv = new Hashtable<String, Object>();
    authEnv.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
    authEnv.put(Context.PROVIDER_URL, env.getRequiredProperty(PROPERTY_NAME_LDAP_URL));
    authEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
    authEnv.put(Context.SECURITY_PRINCIPAL, dn);
    authEnv.put(Context.SECURITY_CREDENTIALS, password);
    DirContext ctx2 = null;
    try {
        ctx2 = new InitialDirContext(authEnv);
    } catch (AuthenticationException authEx) {
        throw new LdapException("Authentication error. Password was wrong");
    } catch(Exception e){
        throw new LdapException(e);
    }finally {
        try{         
            if (ctx2 != null) 
                ctx2.close();
        }catch(Exception e){
            throw new LdapException(e);
        }
    }
}

UPDATE @pczeus code: To set referral=follow I have used this code:

DefaultSpringSecurityContextSource contextSource = new DefaultSpringSecurityContextSource("ldaps://vldp.floal:636/");
contextSource.setUserDn("CN=A0XXX32,CN=Administration,CN=fdam,DC=fg,DC=local");
contextSource.setPassword(password);
contextSource.setReferral("follow"); 
contextSource.afterPropertiesSet();

LdapAuthenticationProviderConfigurer<AuthenticationManagerBuilder> ldapAuthenticationProviderConfigurer = auth.ldapAuthentication();

ldapAuthenticationProviderConfigurer
    .ldapAuthoritiesPopulator(myAuthPopulator)
    .userSearchFilter("(CN={0},CN=ProxyUsers,CN=fdam,DC=fg,DC=local)")
    .userSearchBase("")
    .contextSource(contextSource);

and I receive the classic exception:

2016-04-07 09:34:41 [http-nio-8086-exec-4] ERROR o.s.s.w.a.UsernamePasswordAuthenticationFilter - An internal error occurred while trying to authenticate the user.

if I add .userSearchBase("CN=ProxyUsers,CN=fgadam,DC=fg,DC=local") I receive

where DN is '', why?

In AbstractContextSource (parent of LdapContextSource), the Javadoc for the setBase() method says the following: "Set the base suffix from which all operations should origin. If a base suffix is set, you will not have to (and, indeed, must not) specify the full distinguished names in any operations performed.". Since you specify the full DN for the userDN/filter, hence you must not specify the base.

Try setting the userSearchBase either to an empty String (""), or remove the call all togehter.

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception{
     auth.ldapAuthentication()
         .contextSource()
         .url("ldaps://vldp.floal:636/DC=fg,DC=local")
         .managerDn("CN=A0XXX32,CN=Administration,CN=fdam,DC=fg,DC=local")
         .managerPassword(password)
         .and()         
         .userSearchBase("")     
         .userSearchFilter("CN={0},CN=ProxyUsers,CN=fdam,DC=fg,DC=local")
         .ldapAuthoritiesPopulator(myAuthPopulator);     
}
