Hi,

Not sure if this is a PBKAC or not:-

root at ds3:/usr/share/postfixadmin# doveadm pw -s SHA512-CRYPT -p password
{SHA512-CRYPT}$6$aUgGXP0UshkMj7hY$9JV4yMRsjIe/98CzmglYrMjf.9NJ.FXzxcLE9B0v3doCRUWo2wRncc6hg6VCs0DCUHQbeC/bRDZdGCge/nB/h/

root at ds3:/usr/share/postfixadmin# doveadm pw -t {SHA512-CRYPT}$6$aUgGXP0UshkMj7hY$9JV4yMRsjIe/98CzmglYrMjf.9NJ.FXzxcLE9B0v3doCRUWo2wRncc6hg6VCs0DCUHQbeC/bRDZdGCge/nB/h/ -p password
doveadm(root): Fatal: reverse password verification check failed: Password mismatch

root at ds3:/usr/share/postfixadmin# dovecot --version
2.2.9


It works ok with other schemes that i’ve tried (e.g. SSHA-512).

Is this a bug, or my mistake?

thanks

Jon
