authentication data structure similar to a Kerberos ticket that contains a
session key for use in obtaining Ceph services. This session key is itself
encrypted with the user's permanent secret key, so that only the user can
request services from the Ceph monitor(s). The client then uses the session key
request services from the Ceph Monitor(s). The client then uses the session key
to request its desired services from the monitor, and the monitor provides the
client with a ticket that will authenticate the client to the OSDs that actually
handle data. Ceph monitors and OSDs share a secret, so the client can use the
handle data. Ceph Monitors and OSDs share a secret, so the client can use the
ticket provided by the monitor with any OSD or metadata server in the cluster.
Like Kerberos, ``cephx`` tickets expire, so an attacker cannot use an expired
ticket or session key obtained surreptitiously. This form of authentication will

Ceph eliminates the bottleneck: Ceph's OSD Daemons AND Ceph Clients are cluster
aware. Like Ceph clients, each Ceph OSD Daemon knows about other Ceph OSD
Daemons in the cluster. This enables Ceph OSD Daemons to interact directly with
other Ceph OSD Daemons and Ceph monitors. Additionally, it enables Ceph Clients
other Ceph OSD Daemons and Ceph Monitors. Additionally, it enables Ceph Clients
to interact directly with Ceph OSD Daemons.
