  <p>That's what we have installed:</p>
  
  <pre><code>Python - 2.5.5         App Engine SDK - 1.3.2
  PIL    - 1.1.7         ssl            - 1.15

  <p>How can I fix it? Is it well known problem?</p>
  
  <p><strong>Update:</strong></p>
  
  <p>I really had a problems with time synchronization immediately after installing Windows on the same computer where I have Gentoo installed, but I've fixed that soon by setting RealTimeIsUniversal in registry and setting synchronization with europe.pool.ntp.org in both systems. (BTW my time zone is EEST)</p>
  
  <p>A couple of days after I solved a problem with time synchronization appcfg.py asked me for a password after each line it printed out (that was really weird) and I've used --passin and unix 'yes '.</p>
  
  <p>Now I have this problem with "Must authenticate first." and I've spent a lot of time playing with --passin --insecure --no_cookies options in different combinations on both windows and linux without any success.</p>
