[Dovecot] shared namespaces with common prefix prefix

[Frank Cusack]

Can shared/public namespaces' prefixes have a common prefix? :)

namespace public {
  separator = /
  prefix = zz/shared/
  location = maildir:/var/maildir/shared:INDEX=/var/maildir/%n/shared
  subscriptions = no
}
# to share other employees mailboxes (term'd or admin access)
namespace shared {
  separator = /
  prefix = zz/shared/%%u/
  location = maildir:/var/maildir/%%n:INDEX=/var/maildir/users/%%u
  subscriptions = no
  list = children
}

Since I added the shared namespace, I can no longer access the public
namespace.  The folders show up but then trying to access one gets the
error that the mailbox doesn't exist.

If they can't have a common part of the prefix, is that an IMAP limitation
or could dovecot conceivably handle it?
