[Dovecot] Virtual users vacation notices and forwards
by Del Stoliker 14 Jan '05

14 Jan '05

I'm in the process of moving from UW-IMAP to dovecot. I'm exploring the idea of using virtual users with dovecot and storing all user information in LDAP. While bouncing this idea off of a coworker, he asked me how we could handle vacation notices and forwards. Currently, we're using a procmail recipe to generate the vacation notice, and the sendmail .forward file for forwards (although most of our forwarding takes place elsewhere so the .forward file is rarely used). These are, of course, dependant on the user having an account on the mail server. How are those of you using virtual users supporting this functionality? Thanks!

[Dovecot] Strange behavior of mysql 4.1.8/9 + dovecot 1.0-test58~test61 on Fedora 3 x86_64 machine
by #LIU QI# 14 Jan '05

14 Jan '05

I've built & configured the dovecot to use mysql as the passdb and userdb. However, dovecot-auth always claims that the username/password of mysql server is wrong (access denied by mysql server) during the connection. When I set the password to NULL, it can successfully connect to mysql server! I am 100% sure that I typed the correct password (by copy & paste), and I can successfully use this username/password connect to mysql server by mysqladmin and other mysql clients. I even wrote a C program which also successfully connects to mysql server. Furthermore, even I want to use pam_mysql in dovecot, the pam library also claims that it cannot connect to mysql server, but pam_mysql can be successfully used in postfix (exactly the same pam configuration, the same database, the same table, and the same username/password). Can anybody give me a hint why? Thank you very very very very much.... Crying for help....

[Dovecot] Upgraded and authentication fails with LDAP
by Ren Galskap 14 Jan '05

14 Jan '05

FreeBSD 5.2.1 Upgraded to dovecot 0.99.12.1 After authentication failed, I also upgraded OpenLDAP to 2.2.19 Dovecot and OpenLDAP are now the most recent versions in the ports. I can access the LDAP info through the OpenLDAP client without a problem, so slapd seems to be working fine. Both dovecot and OpenLDAP worked fine before the upgrade. Any help will be appreciated, since several people would like to have their e-mail back soon. maillog Jan 13 18:51:02 kongemord imap-login: Internal login failure: rjhjr [127.0.0.1] Jan 13 18:51:02 kongemord dovecot: child 1320 (auth) killed with signal 6 messages Jan 13 18:51:02 kongemord kernel: pid 1320 (dovecot-auth), uid 1006: exited on signal 6 debug.log Jan 13 18:51:02 kongemord slapd[1103]: conn=14 op=1 SRCH base="ou=imap,dc=krig,dc=net" scope=2 deref=0 filter="(&(objectClass=posixAccount)(uid=rjhjr))" Jan 13 18:51:02 kongemord slapd[1103]: conn=14 op=1 SRCH attr=uid userPassword Jan 13 18:51:02 kongemord slapd[1103]: conn=14 op=1 SEARCH RESULT tag=101 err=0 nentries=1 text= Jan 13 18:51:02 kongemord slapd[1103]: conn=14 fd=12 closed Jan 13 18:51:03 kongemord slapd[1103]: conn=15 fd=12 ACCEPT from IP=127.0.0.1:54 185 (IP=0.0.0.0:389) Jan 13 18:51:03 kongemord slapd[1103]: conn=15 op=0 BIND dn="cn=dovecot,ou=imap,dc=krig,dc=net" method=128 Jan 13 18:51:03 kongemord slapd[1103]: conn=15 op=0 BIND dn="cn=dovecot,ou=imap,dc=krig,dc=net" mech=SIMPLE ssf=0 Jan 13 18:51:03 kongemord slapd[1103]: conn=15 op=0 RESULT tag=97 err=0 text= dovecot-ldap.conf hosts = localhost dn = cn=dovecot,ou=imap,dc=krig,dc=net dnpass = <cleartext> ldap_version = 3 base = ou=imap, dc=krig, dc=net deref = never scope = subtree user_attrs = uid,homeDirectory,,,uidNumber,gidNumber user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid,userPassword pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = CRYPT user_global_uid = 1003 user_global_gid = 6 dovecot.conf base_dir = /var/run/dovecot/ protocols = imap imap_listen = * ssl_disable = yes login_chroot = yes login = imap login_executable = /usr/local/libexec/dovecot/imap-login login_user = dovecot verbose_proctitle = yes first_valid_uid = 1003 last_valid_uid = 1003 first_valid_gid = 6 last_valid_gid = 6 valid_chroot_dirs = /var/mail default_mail_env = maildir:/var/mail/%u/Maildir client_workarounds = oe6-fetch-no-newmail outlook-idle outlook-pop3-no-nuls mail_save_crlf = yes maildir_copy_with_hardlinks = yes imap_executable = /usr/local/libexec/dovecot/imap auth = default auth_mechanisms = plain auth_userdb = ldap /usr/local/etc/dovecot-ldap.conf auth_passdb = ldap /usr/local/etc/dovecot-ldap.conf auth_executable = /usr/local/libexec/dovecot/dovecot-auth auth_user = dovecot-auth auth_verbose = yes I had the following flags in the Makefile prior to make: --without-shadow --localstatedir=/var --with-ldap __________________________________ Do you Yahoo!?

[Dovecot] Test 57 -> Test 60
by Andrew Hutchings 13 Jan '05

13 Jan '05

I just tried upgrading one of our mail cluster servers to test60 from test57. We have dovecot connecting to 3 different MySQL tables in 3 sql conf files. The error seems to stem from this: Jan 13 14:57:59 svr21 dovecot: auth(sql8): file auth-client-connection.c: line 31 (auth_client_send): assertion failed: (conn->refcount > 1) After this the auth process gets killed with signal 6. The sql8 is the config in use at the time, but can be any of the 3. I take it this is the auth process not liking the 3 auth lookups (refcount > 1)?

[Dovecot] default_ldap_settings' value
by Kazuo Moriwaka 13 Jan '05

13 Jan '05

Hello, When I tested LDAP auth dovecot-auth caught segv, and I found that auth_cache_parse_key() doesn't check query == NULL. I think db-ldap.c/default_ldap_settings.pass_filter should have non-null default value. Please check following patch. regards, -- Kazuo Moriwaka <moriwaka(a)valinux.co.jp> Index: db-ldap.c =================================================================== RCS file: /home/cvs/dovecot/src/auth/db-ldap.c,v retrieving revision 1.24 diff -r1.24 db-ldap.c 62c62 < MEMBER(pass_filter) NULL, --- > MEMBER(pass_filter) "(&(objectClass=posixAccount)(uid=%u))",

[Dovecot] Dovecot create mbox files. But why?
by Mirko Schulze 13 Jan '05

13 Jan '05

Hi there, my dovecot is now running normaly, but there is a small problem.... We want to to use the maildir format at the mailstorage. But the imap part of dovecot creates the for mbox specific files, but why? I created a passwd-file for a testuser. At this tme, there is only on line: test2@dev2.abc.de:ujAN28k8.5zV2:99:99:*:*:*:* in dovecot.conf are these interesting lines: auth_userdb = static uid=99 gid=99 home=/vrmd/pop3imap/links2mailboxes/%u/Maildir auth_passdb = passwd-file /vrmd/mailin/conf/pop3imapdb.passdb.txt I think, if a path ends of /Maildir dovecot will autodetect the maildir format. So what is wrong? Regards Mirko

[Dovecot] using separate authentication based on protocol
by Marius Stan 13 Jan '05

13 Jan '05

Hello, I wonder if it's possible to use a different query for authenticating users against the mysql db based on the protocol used: IMAP or POP3. This could come handy for not allowing my users who switched to IMAP from accidentally getting all their mail through a POP3 connection. Using dovecot-0.99.10 here. Marius
