similar to: CRAM-MD5 Password Generation Algorithm

Hello, I want to use PostgreSQL to store my Dovecot users. I setup a very basic configuration, following word for word this page http://wiki.dovecot.org/DovecotPostgresql and it works ... almost. In fact, it works if I use PLAIN password scheme in my database. However, I would like to store them encrypted. But, if I replace the password field for my user with {HMAC-MD5}-... (the password

Is there any other mechanism than using passwd files with md5-hashed passwords created by dovecotpw that will support cram-md5 authentication? Has anyone created setups where the passwd databases reside in the individual users home directories? Is it possible to persuade dovecotpw to update the passwd databases automatically. Having to use a text editor to paste in the passwords sets a high

Hi all, Got a question on configuring dovecot, I'm still new at this so I might be doing this all wrong. I want dovecot to authenticate the mail client using CRAM-MD5 so I've setup the config in dovecot.conf: auth default { mechanisms = cram-md5 passdb sql { # Path for SQL configuration file, see doc/dovecot-sql-example.conf args = /etc/dovecot/dovecot-sql.conf

Hi, based on the recent discussion by Bill Cole and Douglas Willcocks I've quickly put together a PHP script which generates MD5 'contexts' for Dovecot's password files: http://www.noerenberg.de/hajo/pub/dovecot_hmacmd5.php.txt The script has not been tested extensively, so use it on your own risk :) Most of the code has been shamelessly stolen from various sources.

The idea of salted hash algorithms is to generate a different hash even if the same text is entered. That can be easily seen with dovecotpw: using NON-salted SHA256, same hash is generated for a given password [root at correio ~]# dovecotpw -s SHA256 -p 123 {SHA256}pmWkWSBCL51Bfkhn79xPuKBKHz//H6B+mY6G9/eieuM= [root at correio ~]# dovecotpw -s SHA256 -p 123

Hi to all! I?m writing a python module (python+sqlalchemy) to manage user and domain configuration on my system (I hope to get a CLI tool, a Web app and even a native Mac app, via PyObjc, from my lib). I?m implementing password crypto, but I have some problem in generating CRAM-MD5 password, dovecot style. I?ve found an old discussion on this mailing list and a piece of Perl that works, but I need

I am looking for PHP functions that implement passwords that much the dovecotpw implementation. I downloaded one from PEAR, Crypt_HMAC, but the passwords it generates look nothing like the dovecotpw passwords, which could be my fault because I know nothing about the field. Is there a guide or some library that implements them to match dovecotpw?

I config postfix+mysql+dovecot for SASL SMTP autentication. It works if set: default_pass_scheme = PLAIN and store plain-text password in mysql I'm change default_pass_scheme = PLAIN with default_pass_scheme = PLAIN-MD5 an store password in mysql with md5('passwd') and dovecotpw -s PLAIN-MD5 -p test {PLAIN-MD5} and md5("test") = 098f6bcd4621d373cade4e832627b4f6 but

When using proxy_maybe CRAM-MD5 authentication fails when the connection is proxied. Is this expected behavior? Is proxy_maybe too simplified for this case? We're using SQL so I could rewrite the query with IFs to fake proxy_maybe and return the password as NULL and nologin as Y, but if it works that way couldn't it work with proxy_maybe? This works: password_query = \ SELECT NULL AS

Howdy, I'm using dovecot and mysql users, and i'm creating the password with: ENCRYPT('some-passwd',CONCAT('$6$', SUBSTRING(SHA(RAND()), -16))) So far so good, everything's fine. Today saw that i didn't enabled CRAM-MD5, but if I do, and the (at least) IMAP client (roundcube/thunderbird/etc) issues CRAM-MD5 it doesn't authenticate. What am i doing wrong, or

Hi, after getting dovecot working with PostgreSQL and plaintext passwords I tried to use md5 encrypted passwords with mozilla. www.roughtrade.net/dovecot says that Mozilla only supports CRAM-MD5 and that CRAM-MD5 is included in HEAD. Now I have two questions: 1) Is the md5 hash stored in passdb with cram-md5 the same as in digest-md5? 2) Is a new dovecot stable build planned within the next two

hello dovecot community, question; if my user database and dovecot installation is currently setup to use plain login passwords, and i want to convert to cram-md5, after i configure dovecot accordingly and reset passwords into cram-md5, if anyone uses plain login method again in the future, will it still work? or must they always from this point on use encrypted passwords? Thanks. -- Thanks,

Hi Timo, Mozilla 1.5 doesn't understand DIGEST-MD5; it only speaks CRAM-MD5 or PLAIN. Maybe other clients have the same problem. My users like Mozilla, so I wrote new code for Dovecot to speak CRAM-MD5, using your mech-digest-md5.c as a reference. Attached diff in two formats i) for current CVS ii) against last release both tested and working with Mozilla and KMail's CRAM-MD5. I

Hello list, our users are authenticated against ldap-server. anything works fine... dovecot: imap-login: Login: user=<xxx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured but now we want to use secure passwords and not only plain over ssl. so we configured dovecot to use cram-md5 and configured the ldap-server with CRAM-MD5 passwords. as client we used thunderbird 2.0 and a

/etc/dovecot.conf: auth default { mechanisms=plain login cram-md5 passdb { #.............. Windows Live Mail: CRAM-MD5 authentication failed. This could be due to a lack of memory on your system. Your IMAP command could not be sent to the server, due to non-network errors. This could, for example, indicate a lack of memory on your system. Configuration: Account: Sheltoncomputers

We have a plethora of accounts for which we would like to enable CRAM-MD5 but their passwords are stored as MD5 hashes. Is there anything we can do? Can we take a linux MD5 hashed password (e.g. $1$fac330ee$wd6Tll...) and convert it to dovecot's CRAM-MD5 format (e.g. {CRAM-MD5}b3f297...)? Thanks!

Hello, The world is not black or white. Yes CRAM-MD5 is old and his successor SCRAM-XXXXXX is not widely available/implemented which is sad. For your need, use TLS and forget about it. Thunderbird is conservative. If you don't configure TLS or TLS is not available, it try to use something that not expose the password. There is plenty of context where TLS is not possible/desirable. And

Hi, please apply the following patch to dovecotpw.
