[Dovecot] LDAP authenticated bind support
by J.M. Maurer 30 Dec '05

30 Dec '05

Recently at Better.be we implemented LDAP authenticated bind support for dovecot. A patch against CVS HEAD is attached. I have not tested it against all possible configurations one can use, but the basic operation seems to be right. As documented in the patch, it adds one new option to the dovecot-ldap.conf configuration file: # Set "auth_bind" to "yes" if you want to use "authenticated binds" # as a login validation mechanism. NOTE: the pass_attrs option # will (naturally) be ignored if you enable this auth_bind = yes Authenticated bind support is implemented asynchronously. This involves 2 asynchronous calls: the first being 'ldap_search' to find the dn to bind against and the second being the actual 'ldap_bind' call. I'd love to hear some feedback on this. Regards, Marc Maurer Better.be B.V.

[Dovecot] Migrating from Courier-IMAP to Dovecot
by Andreas Mimz 27 Dec '05

27 Dec '05

Hi! I'm currently trying to migrate from courier-imapd to dovecot... Unfortunately I'm experiences some difficulties here... Since I don't want any user to notice the change of the server backend I've tried changing the namespace in dovecot.conf to namespace private { separator = . location = maildir:~/Maildir prefix = INBOX. inbox = yes hidden = no } With this setting almost everything works fine! Almost... ;-) Squirrelmail won't show 'INBOX' on the left side of the folder tree... If I configure dovecot without the 'INBOX.' prefix it works fine in Squirrelmail, except that all other eMail clients show all sub-folders as a sub-folder of root and not the inbox... root \- inbox \- sent \- trash \- drafts \- private \- spam instead of root \- inbox | \- sent | \- trash | \- drafts | \- private | \- spam any Idea what could be wrong? I've read the wiki about the courier-migration and also tried the conversion script ... but something is wrong I'm afraid... thanks in advance, Andreas

[Dovecot] inbox problems when moving from server to server
by Eric S. Johansson 27 Dec '05

27 Dec '05

this is probably an FAQ but I moved all the mailboxes from a gentoo server to an ubuntu one and all old inbox messages "disappeared" for. New messages appear and can be read, deleted etc. the old messages can still be found in the Maildir/cur directory like they were on the old mail server. Ownership was changed to user:user and is 600 permissions. Dovecot version: 0.99.14-1ubuntu1 all other mailboxes are fine, all messages visible as far as we can tell. ideas?
