[Dovecot] start_tls on the user and password ldap connection
by Farkas Levente 10 May '05

10 May '05

hi, it seems when dovecot use ldap user and password databases it's not possible to use tls connection and certificate with the ldap connection. wouldn't it be possible to use the same certificate on the ldap connection as used in the ssl_{cert,key}_file parameters in the dovecot conf (or would be possible to use it's own cert in the ldap conf file? yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] problems with ldap auth
by Nuno Lopes 10 May '05

10 May '05

I'm trying Dovecot v1.0-test43 with ldap authentication but can't seem to make it work. I'm getting the following errors in the log: dovecot: Sep 16 19:50:09 Info: Dovecot v1.0-test43 starting up dovecot: Sep 16 19:50:10 Error: Auth process died too early - shutting down What can I do to see where the error is? I have this configuration working with dovecot 0.99.xx . And if I replace the ldap authentication scheme with another one it starts up right. Following some past mailing list sugestions I've also tried removing most of the auth modules from the compilation but it made no diference. You can see my configuration files in: http://iluvatar.portugalmail.pt/dovecot/dovecot.conf http://iluvatar.portugalmail.pt/dovecot/dovecot-ldap.conf (I've intalled the binaries in /opt/dovecot) Don't know how much more data I can provide to help finding out what the problem is here (I think this won't be enough unless there's a known bug). Thanks, -- Nuno Lopes

[Dovecot] trouble getting digest-md5 & ldap working
by Udo Rader 09 May '05

09 May '05

hi, I am trying to set up dovecot with digest-md5 as authentication mechanism and openldap as passdb. My problem is ... that I just can't get it working. PLAIN authentication works as expected, but no luck with digest-md5. An excerpt from the two configuration files: dovecot.conf: --------CUT-------- auth = default auth_mechanisms = plain digest-md5 auth_userdb = ldap /etc/dovecot/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot/dovecot-ldap.conf --------CUT-------- dovecot-ldap.conf: --------CUT-------- user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) default_pass_scheme = plain --------CUT-------- My dovecot installation with plain authentication and OpenLDAP has been quite mature for a long time, so I doubt that it is an issue with openldap. >From Cryrus-SASL I know that in order to get DIGEST-MD5 running it is required to have plaintext passwords in the DIT, but that does not solve anything. syslog tells me this: dovecot-auth: May 08 21:25:09 Error: ldap(frodo): No password in reply So any ideas on where I went wrong?

[Dovecot] transparent proxy
by Mark E. Mallett 09 May '05

09 May '05

I'm excited to see that dovecot 1.0-test series supports transparent proxy, but that excitement is muted by: - the recommendation to avoid 1.0 at present; - the requirement to use SQL authentication. I guess I could ignore the first, but the second is sticky. How hard would it be to hack a different sort of proxy server cue into the authentication? Perhaps one of: If authenticating via passwd, use a gid as an index into a server table (or perhaps have the group name be a server name), If passwd authentication fails, try a starting the proxy to a specific other server and see if one can log in there. Or something else.. I dunno, I'm just looking not to install a SQL server just for this. mm

[Dovecot] index file corruption
by Andy Pastuszak 09 May '05

09 May '05

Hello everyone. I am new to the list, so forgive me if this has been discussed already. My configuration is as follows: Fedora Core 3, fully patched through yum through today. Dovecot 0.9.9.13 Postfix 2.1.5 Using Maildir with Mail stored in ~/Maildir My issue is that, for some odd reason the inbox file index gets corrupt, There is no rhyme or reason as to why it happens or when, but a simple rm -rf ~/Maildir/.INBOX fixes everything (I assume because Dovecot rebuilds the index file.) Has anyone else on the list seen this? Is there some workaround for it? Andy

[Dovecot] Problem (?) with 1.0-stable
by Jakob Curdes 08 May '05

08 May '05

... Version from April 26, gives me the following errors in the imap log file : dovecot: May 04 09:56:58 Error: IMAP(m6933192-4): file mbox-sync.c: line 1262 (mbox_sync_do): assertion failed: (sync_ctx->ibox->mbox_sync_dirty) dovecot: May 04 09:56:58 Error: child 10721 (imap) killed with signal 6 This occurs sporadically and vanishes after some time. Is this something to worry about or not. I have mbox_dirty_syncs = yes Or does this just say "I am falling back to reading the whole mailbox"? Yours, Jakob Curdes

[Dovecot] dovecot 0.99.14 and imaps (SSL) "hangs"
by Frode Nordahl 08 May '05

08 May '05

Hello, I just decided to try dovecot again after a long pause, and I must say that I am very impressed with the speed and resource usage, even when running with UNIX mailboxes. However, I have a problem with SSL. Every two minutes the connection is frozen, and the client has to reconnect after it times out waiting for a response from the server. My IMAP client fetches all headers, and then caches all messages in my mailboxes. However, if I do this while connected to dovecot using SSL (imaps, port 993) the connection times out roughly every two minutes, and the IMAP client must close the connection, reconnect and resume operations from where it left off. This makes resynching a 40000 message 300MB folder take VERY long :-) Using the same client, connected to the same server and syncing the same mailbox connecting to regular imap port (no TLS, port 143), everything works smoothly. The very same client, server and mailbox works flawlessly with uw-imapd and SSL. I have turned on rawlog, and everything seems to be OK. I am unable to dump the wire, because it's SSL, so not sure what to do to debug this. One thing I find a bit strange is that /var/run/dovecot/ssl-parameters.dat is a 0 byte file. Is this normal? Client: Apple Mail 1.3.11 (v622) Server: dovecot 0.99.14, installed from ports on FreeBSD 5 dovecot.conf: Regards, Frode Nordahl

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

[Dovecot] Outlook Duplicates issue is still killing me
by Jeff Ramsey 08 May '05

08 May '05

Hi, I have one pop3 client who has three computers, and he has Outlook XP on two, and 2003 on the third. They are all set to leave a copy of messages on the server, and that causes a duplicate message for every message he gets. I then can tell him to uncheck the "leave a copy on the server" box, and pop his mail, and the duplicates will go away for two or three days, only to start up again. I have a stock Fedora Core 2 server with dovecot and Sendmail. I do a nightly yum, so as to stay up2date. My version of dovecot is 1.0-test42. Has anyone else seen this issue? What can I do to fix it, short of permanently unchecking that box in Outlook? (The user is my boss, and he likes to get his email on all three computers...) -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.
