INSTALL

This document contains step by step instructions to install automx.

automx Download

If you haven't done so yet download automx from its website:

$ wget http://automx.org/download/latest.tar.gz

Unpack the tar archive and change into the newly created directory:

$ tar xzf latest.tar.gz
$ cd automx-VERSION

Software Requirements

automx is a Python application. You must install a few extra modules to handle
frontend and backend communication as well to deal with XML data.

frontend
    Install mod_wsgi for the Apache web server and the python-wsgi module.
backend (optional)
    If you plan to use either LDAP or SQL as backends to retrieve configuration
    options from install ldap for LDAP and python-sqlalchemy for SQL. Further
    you also need to install the SQL backend driver that communicates with your
    database. For MySQL this might be mysqldb.
XML handling
    Install the python-packages dateutil, ipaddr, lxml and memcache. Otherwise
    automx will not be able to handle the XML data it needs to deal with.
plist (mobileconfig) handling
    Mobileconfig profiles may be signed with your webservers cert and key. You
    need to install M2Crypto, which does the S/MIME-signing.

Once you've satisfied the requirements, you can start to install automx.

Installing automx

automx is a wsgi script depending on some automx-specific libraries. It reads
its configuration from a single configuration file. The program, the libraries
and the configuration file need to be installed at different locations.

Installing the program

Create a directory for the automx program and copy it to that location:

$ mkdir -p /usr/local/lib/automx
$ cp automx-VERSION/src/automx_wsgi.py /usr/local/lib/automx/

Installing the test program

Copy the automx-test program to a location that is in your $PATH:

$ cp automx-VERSION/src/automx-test /usr/local/bin/automx-test

Installing automx-specific libraries

Python loads packages from various locations depending on your distribution and
python version. To correctly determine the used paths please type the following
commands:

$ python
>>> import sys
>>> sys.path
>>> (CTRL+D)

You'll get a list of used paths. Please remember the first shown path entry
(for example '/usr/lib/python2.7') - this is the best location for placing the
automx-directory:

$ cp -r automx-VERSION/src/automx /usr/lib/pythonVERSION

Installing man Pages

Try using the manpath command to find out where man pages are stored on your
computer:

$ manpath /usr/local/man:/usr/local/share/man:/usr/share/man

Copy the man pages to that location:

$ cp -a automx-VERSION/doc/man/ /usr/local/share/man

Installing the configuration file

Place the sample automx.conf file into /etc:

$ cp automx-VERSION/src/conf/automx.conf /etc/

Follow automx.conf(5) Adopt this configuration file to your needs. You may find
detailed information in the man page automx.conf(5).

Tip

Set debug=yes in the section automx while you setup, configure and test automx.
It will help you detect problems more easily. This will log the request GET/
POST and the response to the error.log file(s).

DNS Configuration

Mail clients seeking mail account autoconfiguration will either request an IP
address for autoconfig.example.com (Mozilla schema) or autodiscover.example.com
(Microsoft schema). Provide settings in your DNS that directs them to the
server running the automx service:

autoconfig.example.com.              IN    A     192.168.2.1
autodiscover.example.com.            IN    A     192.168.2.1

Note

If you install automx on an existing host, which has it's own domain-name, then
it is also possible to use above entries as nicknames:

somehost.example.com. IN A 192.168.2.1
    autoconfig IN CNAME somehost autodiscover IN CNAME somehost

Web Server Configuration

Finally configure the web server. It will accept configuration requests from
mail clients, pass the information to automx and in turn will respond with
account profiles once automx has figured out the details.

First enable the wsgi module. Follow your OS documentation to find out how it
needs to be done. (e.g. 'a2enmod wsgi' for Apache on Debian)

automx is able to provision mail clients following the Mozilla autoconfig
schema as well as mail clients following the Microsoft autodiscover schema.
Both schemas have different requirements regarding hostname, port and level of
security when a request is sent to the configuration server:

Microsoft
    Mail clients following the Microsoft autodiscover schema require a https
    connection. The web server must identify itself as autodiscover.example.com
    on port 443 and it must use a valid server certificate that is trusted by
    the mail client requesting configuration.
Mozilla
    Mail clients following the Mozilla autoconfig schema can use either a http
    or a https connection. The web server must identify itself as
    autoconfig.example.com on port 80 or 443. If it connects on 443 a valid
    server certificate that is trusted by the mail client requesting
    configuration has to be used.

To provision Apple iOS devices or Mac OS X Mail, you need to place the file
automx.html somewhere in your document root of your webserver. After that you
can use your iOS device and open the Safari browser calling this website. After
entering the form data, you will receive a mobileconfig file and the device
switches to the settings assistent. On Mac OS X, you also can call this
document and save it to disk. After opening it, the profile manager opens and
the steps are similar to iOS. For signed profiles see the man page automx.conf
(5).

Here is a simple example that configures an autoconfig and an autodiscover
service (both use the same automx script). You need to copy & paste this lines
into your existing website configuration files (for Debian take a look in /etc/
apache2/sites-enabled/...):

<VirtualHost *:80>
        ServerName example.com
        ServerAlias autoconfig.example.com
        ServerAdmin webmaster@example.com
        <IfModule mod_wsgi.c>
                WSGIScriptAliasMatch \
                        (?i)^/.+/(autodiscover|config-v1.1)>xml \
                        /usr/lib/automx/automx_wsgi.py
                <Directory "/usr/lib/automx">
                        Order allow,deny
                        Allow from all
                </Directory>
        </IfModule>
</VirtualHost>

<VirtualHost *:443>
        ServerName example.com:443
        ServerAlias autodiscover.example.com:443
        ServerAdmin webmaster@example.com
        <IfModule mod_wsgi.c>
                WSGIScriptAliasMatch \
                        (?i)^/.+/(autodiscover|config-v1.1)>xml \
                        /usr/lib/automx/automx_wsgi.py
                WSGIScriptAlias \
                        /mobileconfig \
                        /usr/lib/automx/automx_wsgi.py
                <Directory "/usr/lib/automx">
                        Order allow,deny
                        Allow from all
                </Directory>
        </IfModule>
</VirtualHost>

Note

If you haven't done so, you also need to configure and enable SSL in your
apache-configuration. At least that means enabling the default SSL-site,
install (self signed) certificates and activating the ssl-support (e.g.
'a2enmod ssl' for Apache on debian). Don't forget to restart your web-server
afterwards! You need also to ajust the paths to automx_wsgi.py in the example
above.

Note

For Nginx see the example configuration file nginx-automx.conf. You can place
this file into /etc/nginx/conf.d (this depends on your distribution) and adopt
it to your needs.

Note

ISPs

In an advanced environment with thousands of domains, you can redirect mail
clients via DNS entries to your ISP automx provisioning server for Microsoft
clients and a web server instance with a wild card ServerName to serve the
Mozilla schema.

Add this to your DNS-configuation:

*.example.com. A 192.168.2.1

and this to your virtualhost-definition in your webserver-configuration:

ServerAlias *.example.com

automx comes with a little utility that helps testing proper operation. The
next section explains how to use it.

Testing And Debugging automx

The automx-test utility sends configuration requests for Microsoft and Mozilla
clients to the web server:

$ automx-test user@example.com

The domainpart in the address determines the list of hostnames that will be
queried. In this example autoconfig.example.com and autodiscover.example.com
will be contacted.

You should see the web server header. The script will say Success or Failed.

If things go wrong, the error.log is your friend. It will indicate
configuration issues, if python modules are missing, if your database can not
be queried or anything else that might go wrong. If you also enabled debug in /
etc/automx.conf, you will find further information in your automx.log file.
Please turn on debug, if you want to send us a bug report. PLEASE NOTICE!
Mobileconfig will display a users password in cleartext! So please remove that
from bug reports first!

Note

If you split error logs by port, e.g. port 80 and 443, you need to check both.
Autoconfig requests will mostly show up in the port 80 error.log, whereas
autodiscover will only show up in your 443 error.log.
