[Dovecot] doveadm password check

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
