cyradm --user username at domain.name  servername

 with the password entered correctly I can check the apparent ACL, and get 
lrswipcda.  The c would imply that I can create subfolders happily.  But when 
I try it I get:

cm inbox.test
createmailbox: Permission denied

I can receive and delete emails happily, fetchmail is working great, but this 
seems to be my last stumbling block to migrating my imap to the kolab server.

The logs don't show anything when I try this.

Any ideas?
