Thanks for your answer, but I think that I don't explained my problem very
clearly. Lets take this simple situation. I have two hosts: my client with
apache+mod_python and my ipa server.

This is the apache configuration on client :

---------------------------------------------------------
 <Files "test">
  ## python conf


  PythonPath "['/usr/lib/python2.6/site-packages/webservices']+sys.path"
  SetHandler python-program
  PythonHandler my_script
  PythonDebug on
</Files>
---------------------------------------------------------

and this the code of `my_script`

---------------------------------------------------------
from mod_python import apache

def handler(req):
    req.content_type = "text/plain"
    req.send_http_header()
    from ipalib import api
    # I am on the client host => mode server is False
    # I also tested this with api.bootstrap(context='example',
in_server=False) but it doesn't work too
    api.bootstrap_with_global_options(context='example')
    api.finalize()
    api.Backend.xmlclient.connect()
    res = api.Command.user_show(user_name)
    req.write(str(res))

    return apache.OK
---------------------------------------------------------

when I access to client.domain.org/test on my browser I get this error :

---------------------------------------------------------
MOD_PYTHON ERROR

ProcessId:      12393
Interpreter:    'client.domain.org'

ServerName:     'client.domain.org'

StandardError: API.bootstrap() already called
---------------------------------------------------------

I don't know where API.bootstrap()  was called.
