Create a second domain, create users in there and then go int your
DB (phpMyAdmin) copy all the stuff from the new domain and replace it
with your existing one and the installed accounts. After that, change
the passwords via web-cyradm to the existing ones.
And don't forget: Create Backups before!!!
