It was too slow when stretching 60000 on powerless server.
My tiny VM needed over 1sec if iterate 60000 by PBKDF2-SHA512.
RFC recommends more than 1000 iterations, it would be safe enough 10000 iterations.
FYI: http://security.stackexchange.com/questions/3959/recommended-of-iterations-when-using-pkbdf2-sha256

It is desirable to be able to change the operator, but slapasswd does
not read slapd.conf so I was stuck.
I'm planning to change slappasswd that accept iteration count in the future.
Thank you.
