-user can bog down all requests by hammering it with bad auth requests causing
 the auth facility to get bogged down in PBKDF
    Option:
        -a multiprocessing pool to handle new authentications.  The auth action
         itself would be stalled out whilst an attack was underway, but once
         in, the respective session layers will provide a caching session that
         should accelerate things after the client gets in once
        -penalizing a client clearly trying to break in
-other auth
    -pam if user exists but has no passphrase
    -keystone?
    -ad? (specialized to the AD case)
-expressionkeys never gets smaller - perf impact
-need event notification for config change- e.g. set attribute triggers consol
 session object check to see if credentials changed
 design is that calling code on init registers a callback for related node to
 the in-context config manager object.  callback shall be OO so no context
 object parametr passed in.  ipmi will use it for user/password/hardwaremanagement.manager
 changes to console and command objects.  console will use it to hook add/deletion
 of nodes and/or indicating a different console.method or hardwaremanagement.method
-When the time comes to dole out configuration/discovery, take page from xCAT
    'flexdiscover' command, if possible bring an ipmi device under management
    by way of ipv6 to eliminate requirement for ip to be specified.
    Requires the polling event support (which is required for security anyway)
