[horde] Virtual host configuration

[Francine.Bolduc at ti.csaffluents.qc.ca]

Hi, 

I have been asked, first time ever, to work on Horde and to install the 
new version of Horde 4 and IMP 5. I have been working hard for weeks to 
understand that system, and can now send et receive emails et access the 
mail directory of our School Board. Unfortunetaly, I can't solve the 
problem of accessing Horde from two domain names : 

www.educsadev.org (for personel) 
www.elecsadev.org (for students) 

In httpd.conf, I have created 2 virtual hosts : 

<VirtualHost *:80> 
DocumentRoot /var/www/html/ 
ServerName www.elecsadev.org 
ServerAlias elecsadev.org 
ErrorLog logs/elecsadev-error_log 
CustomLog logs/elecsadev-access_log common 
DirectoryIndex index.html index.html.var index.php horde/imp/index.php 
Alias /Microsoft-Server-ActiveSync /var/www/html/horde/rpc.php 
</VirtualHost> 

<VirtualHost *:80> 
DocumentRoot /var/www/html/ 
ServerName www.educsadev.org 
ServerAlias educsadev.org 
ErrorLog logs/educsadev-error_log 
CustomLog logs/educsadev-access_log common 
DirectoryIndex index.html index.html.var index.php horde/imp/index.php 
Alias /Microsoft-Server-ActiveSync /var/www/html/horde/rpc.php 
</VirtualHost> 

In the configuration , I have put $conf[vhosts] at true and created 2 
configuation files in /horde/config/ : 

conf-educsadev.org.php 
conf-elecsadev.org.php 

But now, I don't know what to do from here. 
How Horde uses those files ? 
How can I create preferences for each ? 

Thanks
Francine
