I can't create top-level folders

[Francesc Guasch]

Hi. I just migrated to cyrus-2.2. I wan't to add a shared
folder so I need to create a top-level folder.

I login as an admin user to cyradm but I can't create it. I checked
the permissions, and they look fine. All the partitions are owned by
the cyrus user.

I see nothing in cyrus.log nor syslog or auth.log.

Any help would be appreciated. Thank you very much.
