Cyrus setup for eGroupWare

[admin at webshop-software.ch]

Dear list readers,

I tried to find any documentation on setting up Cyrus on Ubuntu 11.10
server so that Cyrus can be managed using eGroupWare. This page -
http://community.egroupware.org/index.php?page_name=wiki&lang=&wikipage=Dependencies
- says that if the Cyrus is configured with Postfix and LDAP, when the
eGroupWare will be able to manage email accounts. But I could not find any
documentation on setting up Cyrus with Postfix and LDAP on Ubuntu 11.10.
Please help me to configure it.

Regards,
Sasha
