[Dovecot] [PATCH] yet another NTLM update
by Andrey Panin 02 Nov '04

Hello, after more than week using dovecot as exim4 authentication backend, I noticed that some strange clients send type 3 messages with LM response only. Attached patch allows them to log in. Please consider applying. Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke(a)donpac.ru | PGP key: wwwkeys.pgp.net

[Dovecot] Logging and libwrap
by Jesse 01 Nov '04

01 Nov '04

Hi, A few things regarding logging and libwrap.. a) PAM_RHOST patch Back in July, dean gaudet helpfully posted a patch to dovecot PAM_RHOST the remote IP. Is this going to be included in the main dovecot tree? It seems like a worthwhile addition. The more informative and concise the logging the better. See http://www.dovecot.org/list/dovecot/2004-July/004011.html for the original message. b) Better logging Is it possible to get logging of when a client connects and disconnects? I'm very used to seeing this information and it's very useful for debugging user sessions. It's frustrating not being able to easily tell whether a user has opened a connection. Really many of the log messages could be more verbose. For instance, on disconnect, I see imap-login: Disconnected [ip.here] but the username they were logged in as isn't included. It would be nice to have that rather than having to dig back for a login message with the same IP. Heck, even the pid isn't logged. That would be nice too. c) libwrap Any chance of getting libwrap support built into dovecot? Right now I'm running dovecot out of xinetd, so that I can see when tcp connections are opened, and take advantage of tcpwrappers. But this causes the problem that dovecot thinks all connections come from the local host. Correlating logins to IPs gets to be a lot of hassle, with the information divided over so many lines, while needing multiple ways to track which messages from xinetd, dovecot and pam match each other. With some of the minor logging changes (more info on one line, notification of tcp connections), plus libwrap, it'd be much simpler and much more informative. :) Thanks for the great imap server. Just thinking of some improvements. :) --- Jesse <j(a)lumiere.net>

[Dovecot] Test51 compile problems
by Greg Deputy 01 Nov '04

01 Nov '04

First of all, thanks for a great product. I've been able to get dovecot up and running with minimum pain. Very nice. Running Fedora Core 2 with postfix using mysql for virtual mailbox config. Got release version of dovecot working with a passwd-file, then I wanted to try it out with using the same mysql db as postfix, so I downloaded test51. I run ./configure --sysconfdir=/etc --with-mysql And it seems happy. Completes with: Install prefix ...................... : /usr/local File offsets ........................ : 64bit I/O loop method ..................... : poll Building with SSL support ........... : no Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with user database modules . : static passwd passwd-file checkpassword mysql (modules) Building with password lookup modules : passwd passwd-file shadow checkpassword mysql (modules) Then I run make, and it errors out with: gcc -g -O2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -o dovecot-auth auth-cache.o auth-client-connection.o auth-master-connection.o auth-module.o db-ldap.o db-sql.o db-passwd-file.o main.o mech.o mech-anonymous.o mech-plain.o mech-login.o mech-cram-md5.o mech-digest-md5.o mech-ntlm.o mech-rpa.o mech-apop.o passdb.o passdb-bsdauth.o passdb-cache.o passdb-ldap.o passdb-passwd.o passdb-passwd-file.o passdb-pam.o passdb-checkpassword.o passdb-shadow.o passdb-vpopmail.o passdb-sql.o userdb.o userdb-ldap.o userdb-passwd.o userdb-passwd-file.o userdb-static.o userdb-vpopmail.o userdb-sql.o -Wl,--export-dynamic libpassword.a ../lib-settings/libsettings.a ../lib-ntlm/libntlm.a ../lib-sql/libsql.a ../lib/liblib.a -lcrypt -L/usr/local/mysql/lib -lmysqlclient -lz -ldl /usr/local/mysql/lib/libmysqlclient.a(sha1.o)(.text+0x5c): In function `sha1_result': : multiple definition of `sha1_result' ../lib/liblib.a(sha1.o)(.text+0x7f4):/root/dovecot-1.0-test51/src/lib/sh a1.c:242: first defined here /usr/bin/ld: Warning: size of symbol `sha1_result' changed from 158 in ../lib/liblib.a(sha1.o) to 126 in ../lib/liblib.a(sha1.o) collect2: ld returned 1 exit status make[3]: *** [dovecot-auth] Error 1 make[3]: Leaving directory `/root/dovecot-1.0-test51/src/auth' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/root/dovecot-1.0-test51/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/dovecot-1.0-test51' make: *** [all] Error 2 Any help would be appreciated.

01 Nov '04

Hello Timo, we are using dovcot v0.99.11 under Fedora Core 1. We tested following reproducible action with Outlook 2000 SP3, Outlook XP SP3 and Outlook 2003 SP1: folder test with subfolder test1 test test.test1 choose 'move folder' from the context (right-mouse-click) menu of test choose that we want to move folder test into his subfolder test1 (nonsense action, but quite a few employees trying to do that...) Outlook displays error message subscriptions shows correctly: test test1 BUT the directory structure of maildir is .test.test1.test.test1 .test.test1.test.test1.test Is this a mishap of Dovecot or Outlook? Regards, Knut

[Dovecot] dovecot seems to be slow
by Götz Reinicke 01 Nov '04

01 Nov '04

Hi, after the update from wu-imap to dovecot, opening e-mails on the imap server seems slower than with wu-imap. I haven't measured any speed yet, but clicking on a message in a folder takes sometimes a couple of seconds to open the mail. Any ideas or performance tips or information you need?

by Chris L. Franklin 01 Nov '04

01 Nov '04

I've Looked over the list of Auth methods that dovecot can use But i didn't see a option for a custom auth option. Would it be possible to add in a way for dovecot to call a script to check a users login info. have it able to retun the the homedir,gid/uid, and weather or not the password matched. -- Chris L.

[Dovecot] Crash (segfault) while reading folder headers
by Steve Meyers 01 Nov '04

01 Nov '04

Occasionally, while reading the headers of a folder, Dovecot crashes. The visible effect in my mail client is that it will tell me a folder has a new message, but when I click on it, it will take forever to load, and there will be no new messages. When another message comes in to that folder, the folder begins to work again. I generated a core from the latest crash, and the gdb dump is included below. After generating the core file, I removed the .imap.index* files from that folder, and it started working again. I am using Fedora Core 1, with dovecot as an RPM (version dovecot-0.99.10.5-0.FC1). It's a Pentium 4 CPU. Let me know if there is any more information that would help you resolve this. ============================================================== Core was generated by `imap'.
