Confirmed, this is working in my home server now, but with a glich:
when /login is accessed, status 404 is returned to the client and the
returned HTML says "Environment not found". The user will be
authenticated anyway, because the header with the session cookie is
sent in the response. You can remove the "/login" from the URL
afterwards and Trac will see you as authenticated. 

You may see this behaviour at
(try to login as guest).

The traceback looks like the following:

Traceback (most recent call last):
   File "/usr/lib/python2.5/site-packages/trac/web/", line 19,in
     import cgi
   SystemError: Parent module '_wsgi__trac_?' not loaded ,

The config file section for Trac looks contains:

  env PYTHON_EGG_CACHE=/var/tmp/nginx/python-eggs;

  http {
    # some not-wsgi, not trac-related directives here...

    server {
      listen 80;
      wsgi_python_optimize 1;
      include wsgi_vars;
      wsgi_var trac.env_parent_dir /home/trac;
      wsgi_enable_subinterpreters off;

      location /trac {
      location ~ /trac/[^/]+/login {
        auth_basic "Trac";
        auth_basic_user_file /home/trac/passwd;
      location /trac/chrome/common {
        alias /usr/lib/python2.5/site-packages/trac/htdocs;

Any ideas?
