Changing Password Schemes
by Carl A Jeptha 03 May '16

03 May '16

Good Day, I have been following this tutorial without much luck - http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes#CA-26af2b83a43b810052… It is obvious to me that I am not following the instructions correctly and need to be shown what I am misunderstanding. I have an old postfix + dovecot + Roundcube mailserver (mail.domain.Tld). Server clock is loosing time and adjusting it causes dovecot to kill itself, we cannot install more memory, bigger hard-drives, etc. I have built a new server box (mail2.domain.Tld) With Postfix + dovecot + Roundcube. This server is functioning, with a client's new domain, and my personal domain. it's password system is SHA512-CRYPT. I have imported the users from the old server over to the new server. I have created a new column "plain_pass" for the plain passwords. I will be using imapsync to transfer the mail folders from the one server to the other, but will not proceed until I fix this issue. # 2.2.18: /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.8 (0c4ae064f307+) # OS: Linux 4.2.0-35-generic x86_64 Ubuntu 15.10 ext4 auth_mechanisms = plain login first_valid_gid = 8 first_valid_uid = 150 last_valid_gid = 8 last_valid_uid = 150 listen = * mail_gid = mail mail_location = maildir:/var/vmail/%d/%n mail_uid = vmail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota_grace = 10%% quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u } postmaster_address = postmaster(a)airnet.ca protocols = imap pop3 lmtp lmtp pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = mail mode = 0666 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap-postlogin { executable = script-login /usr/local/etc/popafter.sh user = $default_internal_user } service imap { executable = imap imap-postlogin } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3-postlogin { executable = script-login /usr/local/etc/popafter.sh user = $default_internal_user } service pop3 { executable = pop3 pop3-postlogin } ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem ssl_cipher_list = ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA ssl_dh_parameters_length = 2048 ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key ssl_prefer_server_ciphers = yes ssl_protocols = !SSLv2 !SSLv3 userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } -- ------------ You have a good day now, en mag jou môre ook so wees, Carl A Jeptha

issues with doveadm sieve commands
by Michael Grimm 30 Apr '16

30 Apr '16

Hi This is dovecot-pigeonhole 0.4.13 and dovecot 2.2.23 at FBSD 10.3-STABLE. I am used to run doveadm sieve commands for some time now whenever updating a sieve script. Recently those commands fail with a user set explicitly, e.g.: mail> doveadm sieve list -u test doveadm(root): Error: User doesn't exist When asking for all users, I do not run into any error: mail> doveadm sieve list -u '*' user1 default ACTIVE [snip] test default ACTIVE mail> doveadm sieve list -A user1 default ACTIVE [snip] test default ACTIVE That is true for all doveadm sieve commands, but other will work, like: mail> doveadm user -u test userdb: test user : test mail : mdbox:/—path-to-maildir--/test Hmm, any idea what is going on? I do not know when those commands stopped to work, I didn't try to update my sieve scripts for some time now. Thanks and regards, Michael

Password database extra fields and SQL
by Dave 29 Apr '16

29 Apr '16

Hi everyone, first post to the list, be gentle with me! Perhaps I'm missing something here, but it appears to me that many password database extra fields currently aren't much use inside SQL queries? All boolean fields like nologin/nodelay/nopassword are set if the column is present in the returned query, regardless of value (including NULL) For example, say you have a query like: password_query = SELECT hash AS password, NULLIF(active = 1, 'y') AS nologin FROM users WHERE name = '%u' Then nologin will always be set for this account, there's no realistic way to toggle the flag. Has anyone come across any workarounds for this problem that don't sacrifice efficiency by performing multiple lookups? I was considering what would happen if dovecot treated NULL fields as not present, but that immediately conflicts with advice to set password to NULL to satisfy the field requirement on nopassword. Any thoughts? -- Dave
