[Dovecot] doveadm password check

[Thomas Pries]

Hi,

I want to write some php code that users can change there dovecot 
password via a roundcube plugin. I'm using php function crypt(...) to 
generate the hashes and everything works well so far.


I'm using doveadm pw to generate testhashes e.g.:

srv:~ # doveadm pw -r 5 -s BLF-CRYPT -p abc
{BLF-CRYPT}$2a$05$W82/Vw4ZEcHBC00M8cNwe.g8fOHuAeV7L5Q/q4W6VWl9V5kjoiz8y

I expected an "ok" when using -t the hash when entering abc as a 
password, but I got:

srv:~ # doveadm pw -r 5 -s BLF-CRYPT -t 
\{BLF-CRYPT}$2a$05$W82/Vw4ZEcHBC00M8cNwe.g8fOHuAeV7L5Q/q4W6VWl9V5kjoiz8y
Enter password to verify:
doveadm(root): Fatal: reverse password verification check failed: 
Password mismatch

What went wrong?

Kind Regards
Thomas
