You are passing name and password as uri variable:

public  T postForObject(java.lang.String url,
                                     @Nullable
                                     java.lang.Object request,
                                     java.lang.Class responseType,
                                     java.util.Map uriVariables)

                          throws RestClientException

docs.spring.io

If you had some url like: http://yourhost:8080/dosomethingwithemployee/name/password and you extracted name&password from url itself, then it probably would work.

String url = "http://yourhost:8080/dosomethingwithemployee/{name}/{password}"
restTemplate.postForObject(url, request, Employee.class, map);

However, I think you have been trying to send name and password in request body:

public SomeType getResponse(String login, String password) {
        MultiValueMap headers = new LinkedMultiValueMap<>();
        headers.add("Content-Type", "application/json");
        Employee employee = new Employee();
        employee.setName(login);
        employee.setPassword(password);
        SomeType responseBody = post("http://locahost:8080/dosomethingwithemployee", employee, headers, SomeType.class);
        return responseBody;
    }

    public  T post(String url, Object requestObject, MultiValueMap headers, Class responseType) {
        RestTemplate restTemplate = new RestTemplate();
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
        restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

        HttpEntity request = new HttpEntity(requestObject, headers);
        T responseObject = restTemplate.postForObject(url, request, responseType);

        return responseObject;
    }
