Fatal: Unknown scheme: SHA512-CRYPT. On a Mac-mini
Running postfix+dovecot+mysql on a mac-mini, and trying to solve this
puzzle. Is this a Mac issue?, a MySQL issue? or something I haven't
configured in?
You can see from the output of the samples shows in the first case, that
SHA512-CRYPT seems to be Unknown.
The code I used is from a Linux based tutorial on setting up
Postfix+Dovecot+MySQL on a site. Everything is generally going ok, apart

HELP: wrinting dovecot-sql.conf to authenticate to an existing database
hi all,
can anyone help me with dovecot-sql.conf please ? I'm not a mysql expert and I'am trying to authenticate dovecot2 to an existing database.
I have a database "egroupware" with table "egw_accounts". The field "account_lid" is the full email address and "account_pwd" is the password in Blowfish format.
Here is my dovecot-sql.conf

Storing passwords encrypted... bcrypt?
Hi everyone,
Was just perusing this article about how trivial it is to decrypt
passwords that are stored using most (standard) encryption methods (like
MD5), and was wondering - is it possible to use bcrypt with
dovecot+postfix+mysql (or posgres)?

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

2 mysql dbs or 2 types of encryption
Just upgrading to 1.0.0 and I'm trying to switch from PAM (using
pam-mysql) to a direct mysql query from dovecot, and I've got both
md5crypt and crypt passwords in a password db.
http://wiki.dovecot.org/Authentication/PasswordSchemes seems to indicate
that I have to pick 1, but that is per auth-worker, right?
So, I created 2 auth workers using 2 dovecot-sql config files specifying

Blowfish hashed passwords
>> Maybe, Dovecot could just add support for BLF-CRYPT by using the open source implementation of Blowfish hashing found in https://github.com/php/php-src/tree/master/ext/standard <https://github.com/php/php-src/tree/master/ext/standard>. The implementation looks like a single function to generate the hash. I?m not much of a programmer, but it would seem to me that these .c/.h files

blf-crypt
Hi
The blf-crypt password schema mentioned in the docs could be a solution to my auth problem. However, the docs state that actual support depends on the glibc. Mine apparently doesn't.
Does support depend on the glibc's version (mine is 2.15-r2)?
Maybe someone with access to a box with a good enough glibc could do the following and post the hash for the plain password "test"?

support for Blowfish $2y$10$
Hello,
does dovecot support bcrypt $2y$ version? (BLF-CRYPT - Blowfish crypt)
doveadm pw -s BLF-CRYPT
generates a
{BLF-CRYPT}$2a$05$.......
password.
Does this mean that dovecote will not authenticate against a
$2y$10$.......
password?
Thanks in advance,

CRYPT scheme and 8 character limit
I've decided that having users supply cleartext passwords for me to encrypt
and encode is a bad idea, anyway. So maybe I won't need dovecotpw. The
idea is that users supply an already-encrypted password. Most of the users
can fetch their login password from /etc/shadow on their own computer.
Wiki page http://wiki.dovecot.org/Authentication/PasswordSchemes indicates

Blowfish hashed passwords
> I would love to know why your ubuntu 14.04 system doesn't support sha512-crypt.
I just tried SHA512-CRYPT and it is supported on Ubuntu 14.04. I think I was thinking about DBMail instead of Dovecot.
I could really use support for BLF-CRYPT since my current password hashes generated by PHP are using Blowfish encryption.
Maybe, Dovecot could just add support for BLF-CRYPT by using the

Not just less useful, but almost infeasible. Given the use of random
salts, you would have to generate (number of possible salts) rainbow
tables. This drastically changes the CPU/storage tradeoffs.

Blowfish hashed passwords
> Changing your php app will probably be the easiest solution.
Since I?m using Docker, the easiest solution for me is to find a linux distro that can run Dovecot well and supports BLF-CRYPT as well.
What Linux distros support BLF-CRYPT and are well tested and secure?

dovecot 2.2.28 password auth with openldap
Hi there,
I desperatly trying to store a BLF-CRYPT password hash in an LDAP
userPassword Attribute and get dovecot to authenticate against it.
I use a thunderbird as client and send the password plain with starttls.
what worked so far but is kinda problematic for my smtp authenticaton
was to store the has with the prefix {CRYPT} or {BLF-CRYPT}.
Is there a way to get dovecot to authenticate

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

argonid and dovecote
on a FreeBSD 11.2 amd64 machine, I am trying to get Dovecot 2.3.4 to play
nice with "argonid" encryption.
In the "10-auth.conf" file, I tried:

Upon restarting dovecot, I received an error message when attempting to
