Bug description:
Keystone uses sha512_crypt for password hashing. This is insufficient
and provides limited protection (even with 10,000 rounds) against
brute-forcing of the password hashes (especially with FPGAs and/or GPU
processing).
The correct mechanism is to use bcrypt, scrypt, or pbkdf2_sha512
instead of sha512_crypt.
This bug is marked as public security as bug #1543048 has already
highlighted this issue.
