Hello,
If I try to use the crypt schemes provided by libc. I fail as follows:
jnikula@jlaptop:~/$ doveadm pw -s SHA512-CRYPT -p 123456

Using SHA512 sum scheme (-s SHA512) works ok in the same manner.
I have dovecot version 2.2.9 on Linux 3.11.0-14-generic x86_64 Ubuntu
13.10 and I get the same results on 32-bit Debian as well. Does anyone
have idea what's wrong?
You're being bitten by shell interpretation/expansion. You need to make
the hash an uninterpretted literal (in bourne-type shells, wrap it in
single quotes):
# doveadm pw -s SHA512-CRYPT -p 123456
{SHA512-CRYPT}$6$ZmAHfx//YBcuQdpt$/vUoc3G7y/v9JMSfrz0zhdBTs2U5ZmyLZbB6BEpV3BBi8f9N70kNf6xZWAnhE.hQn46pQhpIwnziIdNfjlAKu1
