Installing Kallithea on Microsoft Internet Information Services (IIS)

=====================================================================

The following is documented using IIS 7/8 terminology. There should be nothing

preventing you from applying this on IIS 6 well.

.. note::

    For the best security, it is strongly recommended to only host the site over

    a secure connection, e.g. using TLS.

Prerequisites

-------------

Apart from the normal requirements for Kallithea, it is also necessary to get an

ISAPI-WSGI bridge module, e.g. isapi-wsgi.

Installation

to run on the website and neither will Kallithea.

.. note::

    The application pool can be the same as an existing application pool,

    as long as the Kallithea requirements are met by the existing pool.

ISAPI handler

.............

The ISAPI handler can be generated using::

This will generate a ``dispatch.py`` file in the current directory that contains

the necessary components to finalize an installation into IIS. Once this file

has been generated, it is necessary to run the following command due to the way

that ISAPI-WSGI is made::

    python2 dispatch.py install

This accomplishes two things: generating an ISAPI compliant DLL file,

``_dispatch.dll``, and installing a script map handler into IIS for the

The ISAPI handler is registered to all file extensions, so it will automatically

the ISAPI handler, it will start a thread pool managed wrapper around the paster

middleware WSGI handler that Kallithea runs within and each HTTP request to the

site will be processed through this logic henceforth.

Authentication with Kallithea using IIS authentication modules

..............................................................

The recommended way to handle authentication with Kallithea using IIS is to let

IIS handle all the authentication and just pass it to Kallithea.

To move responsibility into IIS from Kallithea, we need to configure Kallithea

to let external systems handle authentication and then let Kallithea create the

user automatically. To do this, access the administration's authentication page

and enable the ``kallithea.lib.auth_modules.auth_container`` plugin. Once it is

added, enable it with the ``REMOTE_USER`` header and check *Clean username*.

Finally, save the changes on this page.

Switch to the administration's permissions page and disable anonymous access,

otherwise Kallithea will not attempt to use the authenticated user name. By

default, Kallithea will populate the list of users lazily as they log in. Either

disable external auth account activation and ensure that you pre-populate the

user database with an external tool, or set it to *Automatic activation of

different options for finding issues exist: IIS' failed request tracking which

is great at finding issues until they exist inside Kallithea, at which point the

ISAPI-WSGI wrapper above uses ``win32traceutil``, which is part of ``pywin32``.

In order to dump output from WSGI using ``win32traceutil`` it is sufficient to

type the following in a console window::

    python2 -m win32traceutil

and any exceptions occurring in the WSGI layer and below (i.e. in the Kallithea

application itself) that are uncaught, will be printed here complete with stack

traces, making it a lot easier to identify issues.

for this, it is recommended to use a crontab entry. Example::

    0  3  *  *  *  /path/to/virtualenv/bin/paster make-index /path/to/kallithea/my.ini

When using incremental mode (the default), Whoosh will check the last

modification date of each file and add it to be reindexed if a newer file is

available. The indexing daemon checks for any removed files and removes them

from index.

If you want to rebuild the index from scratch, you can use the ``-f`` flag as above,

or in the admin panel you can check the "build from scratch" checkbox.

Setting up LDAP support

-----------------------

Kallithea supports LDAP authentication. In order

to use LDAP, you have to install the python-ldap_ package. This package is

available via PyPI, so you can install it by running::

    pip install python-ldap

.. note:: ``python-ldap`` requires some libraries to be installed on

          your system, so before installing it check that you have at
