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.

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 [email protected] WSGIScriptAliasMatch (?i)^/.+/(autodiscover|config-v1.1)>xml /usr/lib/automx/automx_wsgi.py <Directory "/usr/lib/automx"> Order allow,deny Allow from all

<VirtualHost *:443>
	ServerName example.com:443
	ServerAlias autodiscover.example.com:443
	ServerAdmin [email protected]
	<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!

.. 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 [email protected]

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.
