Autocreate not working (?)

[Denis BUCHER]

Hello,

We are trying to migrate from Suse+Cyrus+postfix to Debian+Suse+postfix
but we have a problem. When a user logs in for the first time, the Inbox
is not created automatically... Does someone knows if we have to add
something to cyrus config or why it doesn't work ?

For your information, installed cyrus is cyrus-imapd-2.2
 2.2.13-14+lenny3.

It was working perfectly under SuSE Linux (SLES)

Thanks a lot for any help...

Denis
