dovecot - Jun 2015 - Testing SHA512-CRYPT password hashes with doveadm pw -t fails

Hi,

I use Debian jessie with Dovecot 2.2.13-11.
While writing a script for Horde to change the passwords in my passwd
file I noticed doveadm pw -t fails for SHA512-CRYPT:

# doveadm pw -s SHA1 -p test
{SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M# doveadm pw -t
{SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= -p test
{SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= (verified)

# doveadm pw -s SHA512-CRYPT -p test
{SHA512-CRYPT}$6$8FfoioQWQDR/Vuzu$ynKiO/E6Xf4dMvfx2LsP9KQotqy5cEOEppnEh5Hqe1UpCYAgOwSIJlNb0O65fxdYcRZH3gNFQ7ZOM/2kD/R811
doveadm pw -t
{SHA512-CRYPT}$6$8FfoioQWQDR/Vuzu$ynKiO/E6Xf4dMvfx2LsP9KQotqy5cEOEppnEh5Hqe1UpCYAgOwSIJlNb0O65fxdYcRZH3gNFQ7ZOM/2kD/R811
-p test
doveadm(root): Fatal: reverse password verification check failed: Password
mismatch


If this can't work for SHA512-CRYPT then at least the error message should
be more helpful.

Or am I understanding the -t option wrongly?
Then this sohuld be maybe somewhere clarified.

I just use now doveadm auth test which works fine.

doveadm pw -t
'{SHA512-CRYPT}$6$8FfoioQWQDR/Vuzu$ynKiO/E6Xf4dMvfx2LsP9KQotqy5cEOEppnEh5Hqe1UpCYAgOwSIJlNb0O65fxdYcRZH3gNFQ7ZOM/2kD/R811'
-p test

You have $ in the password, see man-page of shell ...

Args right. This Escaping problem bite me already with my backup script.
Now it works.

Anyway. This mail got me to subscribing the dovecot list.
Now that I have again my own mail server it's good to keep a bit
updated :)
