Add control over session key enctype negotiation
Adds a principal string attribute named "session_enctypes" which can
specify what enctypes the principal supports for session keys. (For
what it's worth, this actually allows one to list des-cbc-md5 as a
supported session key enctype, though obviously this hardly matters
now.)
Add a [realms] section parameter for specifying whether to assume that
principals (which lack the session_enctypes attribute) support
des-cbc-crc for session keys. This allows those who still need to use
allow_weak_crypto=true, for whatever reason, to start reducing the
number of tickets issued with des-cbc-crc session keys to clients
which still give des-cbc-crc preference in their default_tgs_enctypes
list.
[ghudson@mit.edu: Miscellaneous edits, cleanups, and fixes; refactored
test script; documented session_enctypes attribute]
