[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 14 Jan '05

14 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 14 Jan '05

14 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 14 Jan '05

14 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
