Some things about my migration

[strikermdd]

well, i am migrating +1500 accounts from my ldap/dovecot/sendmail old server to Zimbra, i make all migrations of ldap accounts to zimbra, and now i am testing the migration of messages using imapsync, but i see one little thing ... the accounts only be migrated by imapsync if then are logged first !

It´s have some option or trick to avoid this ?

And second it´s about, other part of my migration, the Samba, when i set the users to be a samba account using zimbra-samba zimlets, it´s create their homes folders or i have to create them manually ?

And finnaly the third, i have a updated openfire server running well , it´s possible to integrate the webmessenger of the zimbra to use my OpenFire server instead of the old version of it used by zimbra ?

Thanks for the help.
