locked ldap users
by klemen＠arnes.si 11 Nov '15

11 Nov '15

Hello. I'm having a problem regarding locked users in ldap. We are using 389DS ldap server. We lock our users with nsAccountLock=true. If user successfully logs into dovecot, his credentials gets cached. When this user is locked its credentials still stay in cache. The problem I'm having is that our ldap server returns error code 53 ("Unwilling to perform - Account inactivated"). Dovecot takes this error code and decides that ldap doesnt work so it takes users credentials from cache (like stated in docs). User can still login untill his credentials are cleared from cache. Error message in logs: ldap(USERNAME,193.X.Y.Z,<aaaaaaaaaaaaaaaa>): ldap_bind() failed: Server is unwilling to perform Oct 20 14:39:31 SERVER dovecot: auth: ldap(USERNAME,193.X.Y.Z,<aaaaaaaaaaaaaaaa>): Falling back to expired data from cache Does dovecot reacts to error code 53 as it should? Maybe our ldap server should return different error code - like 49/533 (Account_disabled)? How would dovecot react to error code 49? Currenty we solve this problem by taking list of locked users and clear cache every minute. thank you and best regards, Klemen Andreuzzi Arnes

procmail as a content_filter with dovecot
by Vicki Brown 11 Nov '15

11 Nov '15

I am using Mac OS X Server. OS X Server uses postfix with dovecot set as mail_transport. I want to add procmail to the mix. I cannot use the (typical) mailbox_command = procmail -a "$EXTENSION" because mailbox_transport = dovecot overrides any mailbox_command parameter and it is NOT Possible to change, remove, or otherwise vary the mailbox_transport on OS X server. I'm thinking I should be able to set up a content_filter for procmail, but I've found nothing online to tell me if this is possible or how to declare it. Can anyone help? -- Vicki cfcl.com/vlb twitter.com/vlb

LDAP schema for dovecot proxy?
by Andrey Fesenko 10 Nov '15

10 Nov '15

Hello, I want to deploy dovecot proxy/director with the backend and authorization in LDAP. Dovecot wiki specifies only what is necessary to apply additional arguments that the scheme would have earned a proxy, but no solid LDAP schema. Is there such a scheme, such as the existing scheme http://www.zytrax.com/books/ldap/ape/courier.html http://pro-ldap.ru/sources/schema/qmail.schema http://open.rhx.it/phamm/schema/phamm.schema Unfortunately for the tasks they are not good because they just no dovecot-specific variables

Problem with permissions of the logfile
by Andreas Meyer 07 Nov '15

07 Nov '15

Hello! I want to have dovecot log into a separate file and set log_path = /var/log/dovecot instead of log_path = syslog Dovecot does not start if I do this. Tried to change permissions and overschip of the file, no luck, ha. Deleted it in the hope dovecot creates it but no. If I set log_path = syslog dovecot starts and I see it is running as # ps aux |grep dove root 2429 0.2 0.0 3416 2568 ? Ss 16:42 0:00 /usr/sbin/dovecot -F dovecot 2431 0.0 0.0 3100 2080 ? S 16:42 0:00 dovecot/anvil root 2432 0.0 0.0 3228 2316 ? S 16:42 0:00 dovecot/log root 2434 0.0 0.0 4220 3300 ? S 16:42 0:00 dovecot/config What must be done to have dovecot log into the specified file? Greetings Andreas

Questions on supporting Shared Mailboxes using imapc://
by Nathan Coulson 06 Nov '15

06 Nov '15

I was not able to get a shared mailbox setup working using imapc. Tested using mailboxes on the same server, as well as other servers. We are using dovecot 2.2.10 from Centos 7, following the guide at http://wiki2.dovecot.org/SharedMailboxes/ClusterSetup imapc_host=192.168.5.5 #(Local dovecot server) imapc_master_user= %u imapc_password=TempPass #imapc_user=test2(a)example.com # Added for testing. namespace { type = shared separator = / prefix = shared/%%u/ list = children location = imapc:~/shared/%%u/ } namespace { # used as a control to verify that shared mailboxes work type = shared separator = / prefix = shared2/%%u/ list = children location = sdbox:%%h:INDEXPVT=~/shared2/%%u } dict { acl = mysql:/etc/dovecot/dovecot-sql_aggelos_shares.conf.ext } plugin { acl = vfile acl_shared_dict = proxy::acl } mail_plugins = acl protocol imap { mail_plugins = acl imap_acl } passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } passdb { # for master user logins driver = sql args = /etc/dovecot/dovecot-sql_aggelos_aclmaster.conf.ext master = yes pass = yes } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } I can login using test2@example.com*test@example.com (and see all of test2's email), and it looks like it authenticates ok via imap, but shared never shows up. No issues using shared2 which uses direct access to the mailbox doveadm acl debug -u test(a)example.com shared/test2(a)example.com (Fails, uses imapc) doveadm(test(a)example.com): Info: Mailbox 'INBOX' is in namespace 'shared/test2(a)example.com/' doveadm(test(a)example.com): Info: Mailbox path: /misc/1/2/mail/test@example.com-4/shared/test2@example.com/.INBOX doveadm(test(a)example.com): Info: All message flags are shared across users in mailbox doveadm(test(a)example.com): Info: User test(a)example.com has no rights for mailbox doveadm(test(a)example.com): Error: User test(a)example.com is missing 'lookup' right doveadm(test(a)example.com): Info: Mailbox shared/test2(a)example.com is NOT visible in LIST doveadm acl debug -u test(a)example.com shared/test2(a)example.com/Junk (Fails, contains a folder that exists) doveadm(test(a)example.com): Info: Mailbox 'Junk' is in namespace 'shared/test2(a)example.com/' doveadm(test(a)example.com): Info: Mailbox path: /misc/1/2/mail/test@example.com-4/shared/test2@example.com/.Junk doveadm(test(a)example.com): Info: All message flags are shared across users in mailbox doveadm(test(a)example.com): Info: User test(a)example.com has no rights for mailbox doveadm(test(a)example.com): Error: User test(a)example.com is missing 'lookup' right doveadm(test(a)example.com): Info: Mailbox shared/test2(a)example.com/Junk is NOT visible in LIST doveadm acl debug -u test(a)example.com shared/test2(a)example.com/z (Fails, contains a folder that does not exist.

Our setup is as follows: (Currently does not use Dovecot Director, but has the same issues where shared mailboxes may not be local on the server) * Front servers, that are running dovecot (proxy to backend servers) * Backend Servers, each handle their own local users.
