Theoretically, you can leave your users in Active Directory. There is an
Active Directory LDAP backend for Kolab 1 which works more or less out of the
box. The code is still present in Kolab 2, but it doesn't work anymore. We
are currently fixing the AD backend to work again with Kolab 2. When this is
finished, you will be able to store and manage your Kolab users in AD. The
user authentication against the AD uses SASL. This is part of the stock Cyrus
IMAP server and it only needs to be recompiled to include the necessary
The second part is the mailbox data migration. I don't know any reliable way
to retreive the messages from the Exchange server into the IMAP server
directly without knowing the users' passwords. Secondly, if you need to
migrate other data than email messages (calendar, contact), you have to
create a PST file manually from each mailbox and re-import the PST file
through the client (Outlook) later.
