Dear Everybody: May I ask how to configure dovecot otp one-time verification login, that is, after the user logs in to the mailbox with the password + otp, he can send and receive emails without entering the password + otp again? # This is my settings: # /etc/dovecot/conf.d/10-auth.conf disable_plaintext_auth = yes auth_cache_size = 10M auth_failure_delay = 5 secs

If I were going to do this, I would probably try moving to a Windows 200x AD domain controller, and implementing RSA SecurID on that machine. I have not worked with other OTP solutions. As far as I understand, if Samba is configured as a domain controller, it expects to be able to handle the authentication itself. OTP is , in my opinion, most valuable when you are exposing resources to the

Dear Dovecot experts, we have unusual authentication requirements, namely: - almost all of our user are using a smartcard to connect with our mailserver. Thunderbird is our friend here as it will use the smartcard as an additional certificate store and Thunderbird will do client certificate based authentication when connecting via SSL with a mailserver - there's no way (at least that I know

Hello, I was wondering where I might find more information about using OTP as an authentication protocol with dovecot. In searching, I found a thread from 2004, but not much information about how it has progressed from then. I also saw some promising patches from mid-last year, which if I had to guess are probably the addition of support for the SASL OTP mechanism. Is this available in a

This patchset add support for One-Time-Password authentication mechanisms, both S/Key (RFC 1731) and OTP (RFC 2444) are implemented. Tested with mutt (uses cyrus sasl library for authentication). Patches were made against CVS HEAD. Please take a look. Add auth_cache_remove() function which will be used by OTP code to evict old entries from auth cache. diff -urdpNX /usr/share/dontdiff -x

When I upgraded my old, long running dovecot 1.1 to newer dovecot-1.2.4 + doevecot-sieve- 0.1.12 I observed a change in destination address (-a) parsing. Old behaviour: When Timo introduced this feature (http://www.dovecot.org/list/dovecot/2007-September/025813.html) it was possible to hand over only the detail part. In my sendmail configuration I used "-a +$h", where $h contains the

Hello, Will I be breaking something if I have two users share the same home and/or mail_location (maildir format) in dovecot? Mail will only be delivered to the primary user, the other would be used every now and then to login via imap (webmail). This would be on a CentOS 7 box running dovecot from the packaging system, i.e. dovecot-2.2.10-8.el7 currently. The reason I'd like to do this

Hey all, has anyone ever successfully implemented some form of OTP system with dovecot? Im looking at setting up an OATH/HOTP-TOTP based OTP for our services, but the webmail service (which uses dovecot) is a difficult one. Any info on implementations would be appreciated, Regards, Cor

Dear all A new R package 'otpr' is now available on CRAN. It's a wrapper for the OpenTripPlanner (OTP) API and is primarily aimed at researchers and transport planners who want to use OTP to carry out accessibility studies or generate variables for transport models. The package consists of four main functions: otp_connect() - defines and tests the connection to an OTP instance.

The sieve plugin compares the modification dates of sieve source and compiled script and compiles the script only if necessary. When the managesieve extension is used, it creates a symbolic link for the script. In order to switch between scripts managesieve changes the link only. Therefore the sieve plugin should include the modification date of an symlink in its decision about compilation.

Hi All, I'm not sure what's causing this but every time I copy a file from one of the Macs (details below) to the Samba server the file timestamp is changed to the copy time rather than retaining the last modified time. Does anyone know what could be causing this? Systems: Mac OSX (versions 10.3.x -> 10.4.x) Windows 2000 Professional Solaris 10 running Samba 3.0.11 Tests... Mac

Hello! With many MTAs it is possible to use a special form of adressing: subaddresses or "plussed addresses". For sendmail you can read some information on http://www.sendmail.org/m4/misc_features.html http://www.unix.org.ua/orelly/networking/sendmail/ch24_04.htm#SML2-CH-24-SECT-4-3 In a sieve filter you can analyse these special detail values, the syntax is described in RFC3598

Hi, My goal is to protect my mail account with 2FA, which isn't a crazy idea in 2020. Therefore, I would like to know the possibilities of configuring 2FA for Dovecot. In the documentation there are some hints of e.g. OTP in Dovecot [1] and using FreeIPA with Dovecot [2], where FreeIPA has the ability to enable OTP per user [3]. But I can't really find much practical information about

Hi, Is there any way to use something like OPIE (one-time passwords in everything, S/KEY) with dovecot? Here's what I want to do ultimately: * have an AUTH=XYZ method that relies on S/KEY as provided by the libpam-opie module (well, maybe not through pam) * have dovecot advertise authentication as follows: - local : PLAIN, XYZ - remote (encrypted) : EXTERNAL, and

Hello Peter, I'm using a virtual users model in dovecot where all the mail is stored under the same OS user account anyway, so file/dir permissions won't be a problem. The system users I was referring to are actually completely separate user accounts at the moment with their own uid/gid (and passwordless sudo between them), but I guess they could use same uid/gid and just have

The above version of OpenSSH seems to work fine most of the time, but when I connect to one server in particular I get a very odd looking login prompt: pts/0::mugz!xm[~] ssh -l mugz <host-name-omitted> otp-md5 414 cr6003 ext S/Key Password: otp-md5 265 cr4395 ext S/Key Password: otp-md5 332 cr9989 ext S/Key Password: scripter at crimelords.org's password: I enter my password 3 times in
