Strange behaviour with BLF-CRYPT and SHA*-CRYPT pasword schemas

Wed Mar 6 18:16:48 EET 2019

Greetings,

this is less of a bug report or a help request, but we would like to know if 
someone can explain the following:

Environment: Centos 7 with Dovecot 2.3.4-2

default_pass_scheme = BLF-CRYPT
password hash in database : BLF-CRYPT
login = works

default_pass_scheme = SHA512 or SHA256-CRYPT
password hash in database : BLF-CRYPT
login = also works

default_pass_scheme = BLF-CRYPT
password hash in database : SHA512-CRYPT
login = does not work

Can someone explain these discrepancies?

-- 
Kind regards,
Kristijan Savic
