[Dovecot] LDAP Auth problems with auth_bind=yes
by Rob Coward 18 Aug '06

18 Aug '06

Hi, I first posted this problem a day or two ago and have not seen any responses yet. To clarify my problem, I am authenticating virtual users against Active Directory on Win2k3, where their login id is their email address. I am using an almost identical setup to Suranga's below, however my initial bind user doesn't have access to the userPassword attribute, so I am using: auth_bind = yes This is working fine when users enter their correct email address & password, or if the email address is not found, however if a valid email address is given but the password is incorrect, it seems to kill something in the ldap_auth code as all further connections get a temporary authentication error at the client, and the following in /var/log/maillog: Aug 18 13:04:31 gm-ho-lin-06 dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=::ffff:127.0.0.1 rip=::ffff:127.0.0.1 resp=ADA5OTlAc3RvcmVzLmdhbWUuY28udWsAOTk5MA== Aug 18 13:04:31 gm-ho-lin-06 dovecot: auth(default): ldap(0999@stores.game.co.uk,::ffff:127.0.0.1): bind search: base=OU=Stores,OU=UK,DC=group,DC=game,DC=net filter=(&(objectClass=user)(mail=0999(a)stores.game.co.uk)) Aug 18 13:04:31 gm-ho-lin-06 dovecot: auth(default): ldap(0999@stores.game.co.uk,::ffff:127.0.0.1): ldap_search() failed: Operations error Aug 18 13:04:31 gm-ho-lin-06 dovecot: auth(default): client out: FAIL 1 user=0999(a)stores.game.co.uk temp Aug 18 13:04:31 gm-ho-lin-06 dovecot: imap-login: Aborted login: user=<0999(a)stores.game.co.uk>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Is the auth_ldap code not resetting the ldap connection bind details to the dn/dnpass values for each login ?

[Dovecot] How to change passwords on LDAP Server?
by Luis Motta Campos 18 Aug '06

18 Aug '06

Dear List People Someone here could please send me some advice on changin' LDAP passwords? It seems that everything is working nice, except by dovecot: I can send emails using my new LDAP password trought postfix smtp authentication, I can login to my Intranet website and to the Mod-LDAP protected pages on my company. I just can't POP my mail messages, because Dovecot says "dovecot-auth: ldap(user(a)company.net): password mismatch". I guess this is because I'm incorrectly coding the password. Please help me to figure out the right way to crypt the password so Dovecot can read this from the LDAP. *Extra* *Information:* I made a simpler and smaller test version of the program that I use to change passwords, its attached to the email. The essentials are there. *Versions:* My dovecot is a Debian/Sarge (Stable) 3.1 package. I'm also using Perl, Net::LDAP, Apache with Mod_Perl and OpenLDAP. Everything on linux, of course. Package Version ---- ---- dovecot-common 0.99.14-1sarge0 dovecot-imapd 0.99.14-1sarge0 dovecot-pop3d 0.99.14-1sarge0 perl 5.8.4-8sarge4 libnet-ldap-perl 0.3202-3 apache-perl 1.3.33-6sarge2 slapd 2.2.23-8 kernel-image-2.4.2 2.4.27-10sarge1 Any help, suggestion or comment are welcome.

[Dovecot] OT: best way to move maildirs to another host ?
by Brice Figureau 18 Aug '06

18 Aug '06

Hi, I'm sorry because this mail is a little bit off-topic, but Timo's email titled "1.0RC7 Released" made me think about a possible issue for me. I have to move an old dovecot installation (1.0b2) from an i386 server to a new x86_64 server running latest available dovecot. My concern is about moving all my users' mail stored as maildir onto this new server. What would be the best way to do that ? >From Timo's comment on 32bits->64bits migration, I guess I'll have to move only the maildirs (and get rid of dovecot cache files), right ? Next, from what I remember about maildir, the message names usually contain the inode so that the file name is unique. If I strictly move the files, I can be sure that the moved files won't have the same inodes number as what is in the name. Should I care ? Or should I use something different than scp/rsync to perform the migration ? Thanks for your answers, Regards, -- Brice Figureau <brice+dovecot(a)daysofwonder.com>

[Dovecot] dovecot mbox to dovecot maildir migration
by Michael Blancas 18 Aug '06

18 Aug '06

Hi, I'm migrating accounts from one server with dovecot mbox and pam nss-ldap authentication to a new server with dovecot maildir and mysql auth (no posix accounts). My problem is the pop3 uidl format on the two servers are different, even though I'm using pop3_uidl_format = %08Xu%08Xv in both configs, I'm always re-downloading left messages on my test runs. Is there a way I could reuse the X-UID and X-IMAPbase headers on the converted mails. Issuing the UIDL command via pop3 always give a different result for the mbox and maildir spools. The X-UID and X-IMAPbase headers are present in the converted mails. The first number of X-IMAPbase maps to the mail UIDVALIDITY and the second is the same as X-UID, the mail uid. Thanks.

[Dovecot] kqueue rewrite testing, try #3
by Timo Sirainen 18 Aug '06

18 Aug '06

So, apparently the original kqueue code was working fine after all, although it was much more complex than it really needed to be. So, this time there's a really simple and pretty kqueue implementation: http://dovecot.org/nightly/dovecot-latest.tar.gz Tested that it seems to work with FreeBSD.
