r11270: Move the core CrackNames code from rpc_server/drsuapi to dsdb/samdb.
I'm sure this will not be the final resting place, but it will do for now. Use the cracknames code in auth/ for creating a server_info given a principal name only (should avoid assumtions about spliting a user@realm principal). Andrew Bartlett (This used to be commit c9d5d8e45dd7b7c99b6cf35b087bc18012f31222)
