Fatal: Unknown scheme: SHA512-CRYPT. On a Mac-mini

[Robert Chalmers]

Running postfix+dovecot+mysql on a mac-mini, and trying to solve this
puzzle. Is this a Mac issue?, a MySQL issue? or something I haven't
configured in?

You can see from the output of the samples shows in the first case, that
SHA512-CRYPT seems to be Unknown.
The code I used is from a Linux based tutorial on setting up
Postfix+Dovecot+MySQL on a site. Everything is generally going ok, apart
from this bit. There are some others unknown as well. The codes used to
create my database of passwords follows these output examples.



    MacMini:~ robert$ sudo doveadm pw -s SHA512-CRYPT -p 123456
    Fatal: Unknown scheme: SHA512-CRYPT

    MacMini:~ robert$ mysql --version
    mysql  Ver 14.14 Distrib 5.6.19, for osx10.9 (x86_64) using  EditLine
wrapper
    MacMini:~ robert$ cd



My MySQL Version:

    mysql  Ver 14.14 Distrib 5.6.19, for osx10.9 (x86_64) using  EditLine
wrapper

The MySQL code used to create the user/password table. Which seems to work
fine, and creates the table as it should - even though the resulting
password doesn't appear to be quite right for SHA512-CRYPT

    INSERT INTO `mailserver`.`virtual_users`
      (`id`, `domain_id`, `password` , `email`)
    VALUES
      ('1', '1', ENCRYPT('firstpassword', CONCAT('$6$',
SUBSTRING(SHA(RAND()), -16))), 'email1 at example.com'),
      ('2', '1', ENCRYPT('secondpassword', CONCAT('$6$',
SUBSTRING(SHA(RAND()), -16))), 'email2 at example.com');


What it actually creates is this: This is not a SHA512-CRYPT password??

    mysql> SELECT * FROM mailserver.virtual_users;

    3 |         1 | $6jxK9DWPBrAc | robert at zeus.example.com


Just to be clear,. this is the section of the Dovecot configs that deals
with handling this. BUT.. On the MAC-Mini, SHA512-CrYPT is unknown.

    # List of supported schemes is in
    # http://wiki2.dovecot.org/Authentication/PasswordSchemes
    #
    default_pass_scheme = SHA512-CRYPT


So the question is, what Encryption should I be using, and is this an Apple
thing, or a MySQL thing?
