[Dovecot] Dovecot Crashing after MySQL Auth
by 'Donovan Craig' 06 Jan '05

Hi, I'm running a mixed Debian Woody/Sarge system with Dovecot version: (0.99.12-1) I can't seem to be able to get dovecot working with mysql. It seems to authenticate successfully then crash. This happens when I use the Debian package and also when I've compiled from source. dovecot: Jan 06 12:21:14 Info: Dovecot starting up dovecot-auth: Jan 06 12:21:15 Info: MySQL: connected to localhost dovecot-auth: Jan 06 12:21:15 Info: Login process 8 connected dovecot-auth: Jan 06 12:21:15 Info: Login process 8 sent handshake: PID 11587 dovecot-auth: Jan 06 12:21:16 Info: Login process 9 connected dovecot-auth: Jan 06 12:21:16 Info: Login process 9 sent handshake: PID 11589 dovecot-auth: Jan 06 12:21:17 Info: Login process 10 connected dovecot-auth: Jan 06 12:21:17 Info: Login process 10 sent handshake: PID 11590 dovecot-auth: Jan 06 12:21:32 Info: MySQL: Performing query: SELECT substring(password_hash, 6) AS password FROM popbox WHERE local_part = 'donovan' AND domain_name = 'somedomain.com' dovecot: Jan 06 12:21:32 Error: login: Authentication process 11585 doesn't exist imap-login: Jan 06 12:21:32 Info: Internal login failure: donovan(a)somedomain.com [127.0.0.1] dovecot: Jan 06 12:21:32 Error: child 11585 (auth) killed with signal 11 dovecot-auth: Jan 06 12:21:32 Info: MySQL: connected to localhost dovecot-auth: Jan 06 12:21:33 Info: Login process 8 connected dovecot-auth: Jan 06 12:21:33 Info: Login process 8 sent handshake: PID 11587 dovecot-auth: Jan 06 12:21:33 Info: Login process 9 connected dovecot-auth: Jan 06 12:21:33 Info: Login process 9 sent handshake: PID 11589 dovecot-auth: Jan 06 12:21:33 Info: Login process 10 connected dovecot-auth: Jan 06 12:21:33 Info: Login process 10 sent handshake: PID 11590 ---- Core was generated by `dovecot-auth'.

[Dovecot] Internal login failure
by Peter Clark 06 Jan '05

06 Jan '05

I have discovered an odd problem; some users are able to connect to Dovecot either via pop3 or imap without any problems. Other users, however, aren't, and the following message appears in /var/log/mail.log: --- dovecot-auth: Login process 13 connected dovecot-auth: Login process 13 sent handshake: PID 1313 pop3-login: Internal login failure: user(a)mydomain.tld [195.242.16.30] dovecot: child 1311 (auth) killed with signal 11 --- I'm using Dovecot 0.99.11 (Debian Sarge), and all user information is stored in an LDAP database. Any suggestions? Thanks, :Peter

[Dovecot] imap client library.
by Oon Arfiandwi M. 06 Jan '05

06 Jan '05

Dear Dovecot developers, I have several question about imap client: - Is there any difference if we want to create imap client that connect to Imap server with user mail format Mailbox or Maildir? Dovecot support both of them, are we need to create different imap client to support both of them? - Does anyone have imap client library other than UW's c-client? thanks for your information, -- Oon Arfiandwi M.

[Dovecot] authenticate authenticated users
by Tzafrir Cohen 05 Jan '05

05 Jan '05

Hi I'm using dovecot on a LAN server. I sometimes read mail from the server itself locally with mutt and sometimes remotely with mutt or mozilla . I would like to avoid typing my password whenever necessary but without writing a plain-text equivalent copy of it locally. It feels quite silly to have to type the password locally becase the imapd does not know that the process is indeed a process of the user tzafrir. It has all the information it neeeds to check that. wu-imapd has something called "pre-authentication": the imapd is run by the user unpriviliged to access mail in the user's home directory. As a bonus this works quite nicely with ssh public key authentication. I know that at least mutt and pine support running a custom command for creating an imap connection. But then again, wu-imapd is built quite, well, differently. Any ideas? -- Tzafrir

[Dovecot] compact folders, expunge, etc
by Mail Admin 04 Jan '05

04 Jan '05

Test58 and test59 breaks "compact folders" and "expunge" in thunderbird and evolution. Messages marked for deletion just sit there as if compacting folders or expunging have no effect. Thunderbird continues to behave erratically with dovecot test builds. I haven't been able to test the imap_client_workarounds=tb-negative-fetch option yet as I'm still running test52. Thunderbird displays blank messages when they are opened, but "Edit as new" shows the message contents. Thunderbird also displays messages that appear to be truncated like: > Hi Peter, > > I will not This body part will be downloaded on demand. Thanks, Derek

[Dovecot] PLAIN-MD5 passwords?
by Peter Clark 03 Jan '05

03 Jan '05

After I found out that {CRYPT} doesn't support passwords longer than 8 characters, I decided to switch over to MD5 for user passwords in my LDAP database. However, while I have no problem with Postfix + SASL, Dovecot fails to authenticate. Relevant bits from /etc/dovecot-ldap.conf: user_attrs = mailAddress,,,,, # The search string is identical to what's found in /etc/saslauthd.conf: user_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) pass_attrs = mailAddress,userPassword pass_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) default_pass_scheme = PLAIN-MD5 When I try to connect using either KMail or SquirrelMail (which worked just fine before I switched schemes), the following error appears in /var/log/syslog: ldap(user(a)mydomain.tld): password mismatch But when I try 'testsaslauthd -u user(a)mydomain.tld -p longpassword' it authenticates just fine. I have the line 'password-hash {MD5}' in /etc/ldap/slapd.conf, and I used 'slappasswd -h {MD5}' to create the MD5 versions of the passwords. Dovecot is v. 0.99.11. If I can't figure out how to get it to work with MD5, I guess I'll have to go back to CRYPT, but it would be nice to have longer passwords... :Peter

[Dovecot] Wanted: gnutls11 support
by Jaldhar H. Vyas 03 Jan '05

03 Jan '05

I talked to Timo about this before and even provided the beginnings of a patch but don't have enough time to really do a proper job. Anyway, dovecot doesn't work with recent versions of the GNU TLS library. As a result, I compile the Debian package with OpenSSL. However some of the other libraries used, such as OpenLDAP are linked against GNU TLS so Dovecot is linked against both. And it is suspected this is leading to bugs. So could some kind soul provide Timo with a patch he can include in 0.99.13? -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

Re: [Dovecot] Maildir owner importance
by Roi Efrati 02 Jan '05

02 Jan '05

That last line actually made it possible for me to be able to log into the server :) I am still getting errors from PAM but it starting to look good. Is there a good HowTo on setting Dovecot to comunicate directly to MySql without using PAM in the middle ? Also, Since Postfix is still not working on my server, I can't actually recive Emails. Is there somewere an example of the files that need to be in the maildir that I can put them in there and test that the email client get's the mail out ?
