Answer 1

You cannot retrieve provider instance and then do something like Membership.ValidateUser(username, password).

You need to create a reference to the Authentication Web service, perform login operation (C# example below - you have to do something similar in Python):

string siteUrl = "http://example.com/sites/hr";
AuthenticationService.Authentication client = new AuthenticationService.Authentication();

client.AllowAutoRedirect = true;
client.CookieContainer = new CookieContainer();
client.Url = siteUrl + "_vti_bin/Authentication.asmx";

AuthenticationService.LoginResult loginResult = client.Login(username, password);
if (loginResult.ErrorCode == AuthenticationService.LoginErrorCode.NoError)
{
    string cookie = client.CookieContainer.GetCookieHeader(new Uri(siteUrl));
}

and use obtained cookie.
