Don't try to use Cyrus on AFS. It's a losing proposition from a
performance and data integrity standpoint. Put your cyrus data on
local or SAN connected filestores, and use murder for scalability and
Cyrus' replication for redundancy.
Cyrus *can* tie in with your AFS ptserver for group management, though.
