I know it's late but it might be helpful for others who refer to this page to look for the solution.
You can follow this code: 
    private static HttpResponse authenticateByUsernamePassword(String useName, String password) {
        String uri = Url.getOrgDomainUrl().toExternalForm() + '/services/Soap/u/44.0';
        String body =
            '<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"><Header/><Body><login xmlns="urn:partner.soap.sforce.com"><username>' +
            useName +
            '</username><password>' +
            password +
            '</password></login></Body></Envelope>';
        Http h = new Http();
        HttpRequest hRqst = new HttpRequest();
        hRqst.setEndpoint(uri);
        hRqst.setMethod('POST');
        hRqst.setHeader('SOAPAction', 'VALUE');
        hRqst.setHeader('Accept', 'text/xml');
        hRqst.setHeader('Content-type', 'text/xml');
        hRqst.setHeader('charset', 'UTF-8');
        hRqst.setBody(body);
        return h.send(hRqst);
    }

    private static string getSessionId(string username, string password) {
        HttpResponse response = authenticateByUsernamePassword(username, password);
        if (response.getStatusCode() == 200) {
            Dom.XmlNode resultElmt = response.getBodyDocument()
                .getRootElement()
                .getChildElement('Body', 'http://schemas.xmlsoap.org/soap/envelope/')
                .getChildElement('loginResponse', 'urn:partner.soap.sforce.com')
                .getChildElement('result', 'urn:partner.soap.sforce.com');
            return resultElmt.getChildElement('sessionId', 'urn:partner.soap.sforce.com').getText();
        }
        return null;
    }
