Cant send email via python using gmail - smtplib.SMTPException: SMTP AUTH extension not supported by server

I just want to send an email in python with an attachment

import smtplib, os
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders

def send_mail(send_from, send_to, subject, text, files=[], server="localhost"):
    assert type(send_to)==list
    assert type(files)==list


    msg = MIMEMultipart()
    msg['From'] = send_from
    msg['To'] = COMMASPACE.join(send_to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject

    msg.attach( MIMEText(text) )

    for f in files:

        part = MIMEBase('application', "octet-stream")
        part.set_payload( open(f,"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(f))
        msg.attach(part)

    smtp = smtplib.SMTP('smtp.gmail.com:587')
    smtp.login('fu@gmail.com','fu')
    smtp.sendmail(send_from, send_to, msg.as_string())
    smtp.close()


ATTACHMENTS = ['/tmp/2013-11-04-test.csv']
send_from=['fu@gmail.com']
send_to=['fu@gmail.com']
subject='adfadfadf'
text = 'adfadfadf'
send_mail(send_from, send_to, subject, text, files=ATTACHMENTS)

How do I auth? I have to provide a username and password. How?
