similar to: CRAM-MD5 in Python

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

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

Hi, I'm just in the middle of setting up dovecot to serve IMAPS -- Actually I've finished apart from one thing: CRAM-MD5 passwords. I'm using SQL as a backend for the password storage, and I don't want to store the passwords in plaintext. I've also configured dovecot to be rather restrictive when it comes to authentication methods (only CRAM-MD5 is allowed). To generate the

/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

Daniel, Tobias, Renato and myself have been looking a little bit at the potential underlying reason for why http://llvm.org/perf/ is instable, and have found some clues. I want to share them here to give people with more experience in the frameworks used by LNT (flask, sqlalchemy, wsgi, .) a chance to check if our reasoning below seems plausible. Daniel noticed the following backtrace in the

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

I don't desagree with your vision, but if the use of CRAM-XXXX has to use plaint text password's on the server there's a dark side, or there's a CRAM-XXX that can use encrypted on server side? There's always the thing that can clients don't support it. I think i'm not wrong with what i said, On 20 Jun 2019, at 02:53, FUSTE Emmanuel via dovecot <dovecot at

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

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,

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 all. Im try to make a SMTP Auth using Docecot SASL. Im use swaks for tests. Im store users in LDAP. As im understand for CRAM & DIGEST MD5 we need to store pass in a clear text?...

After upgrading my dovecot installation about a month ago, I have started seeing "Requested CRAM-MD5 scheme, but we have only MD5-CRYPT" message from dovecot in my logs. Any help in finding and correcting the cause will be greatly appreciated. --Richard

Hello. dovecot 2.2.26.0 When testing nopassword extra field (http://wiki2.dovecot.org/PasswordDatabase/ExtraFields) with CRAM-MD5 dovecot doesn't allow any password (while it should) and returns " Authentication failed" while in logs: Nov 17 08:22:34 auth-worker(1551): Info: sql(pepe,127.0.0.1,<Y8amDXpBptV/AAAB>): Requested CRAM-MD5 scheme, but we have a NULL password

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

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

Hello, I am wondering which variant is more secure for user authentication and password scheme. Basically I am looking at both variants: 1) MD5-CRYPT password scheme storage with CRAM-MD5 auth mechanism 2) SHA512-CRYPT password scheme storage with PLAIN auth mechanism In my opinion the option 2) should be safer although it is using PLAIN auth mechanism. Of course I would always use STARTTLS and
