C++ / Boost:: Propery_Tree - Is it possible to take ini config value with dot in name

Question

Here is my code:

My Config.h:

#include <string>
#include <boost/property_tree/ini_parser.hpp>

namespace pt = boost::property_tree;

class Config {
public:
    Config(std::string conf);

    template<typename T>
    T GetConfigValue(std::string configKey, T value = 0){
        pt::ptree tree;
        pt::read_ini(_configFile, tree);
        return tree.get<T>(configKey, value);
    }

private:
    std::string _configFile;
};

Here is how I call it:

#include "Logger.h"
#include "Config.h"
int main() {
    Config * config = new Config("/WorldServer.conf.dist");
    std::string def = "Nothing there.";
    Logger::Log(config->GetConfigValue("WorldServer.MaxPingTime", def));
}

Here is the content of WorldServer.conf.dist:

[WorldServer]
MaxPingTime = 30
MySQL.User = "root"

When I execute

Logger::Log(config->GetConfigValue("WorldServer.MaxPingTime", def));

I see 30 as result which is correct, however when I execute:

Logger::Log(config->GetConfigValue("WorldServer.MySQL.User", def));

i see as result Nothing there.

As far as I understand the . in the MySQL.User is causing the issue.

My question is can I somehow make it work with dot using boost property tree to parse the ini config?
