[Dovecot] Intermitent ldap auth problems benchmarking dovecot
by Maria Arrea 12 Apr '11

12 Apr '11

Hello We are using SLAMD (Distributed Load Generation Engine, www.slamd.com) to benchmark our dovecot server (ldap auth). We are simulating 2.000 simultaneous logins and 20% of them fail. We saw the following errors in the log: Apr 12 09:40:07 buzon dovecot: auth: Error: ldap(correo,192.168.4.153): Request queue is full (oldest added 1 secs ago) Apr 12 09:40:07 buzon dovecot: auth: Error: ldap(correo,192.168.4.153): Request queue is full (oldest added 1 secs ago) Apr 12 09:40:07 buzon dovecot: auth: Error: ldap(correo,192.168.4.153): Request queue is full (oldest added 1 secs ago) We increased auth_worker_max_count from 350 to 3500 (10x increase). Now we see the following errors (still 20% of logins fail): Apr 12 10:14:45 buzon dovecot: imap-login: Internal login failure (pid=29016 id=24783) (auth failed, 1 attempts): user=<correo>, method=PLAIN, rip=192.168.4.153, lip=192.168.4.80, mpid=21284 Apr 12 10:14:45 buzon dovecot: imap-login: Internal login failure (pid=29016 id=24784) (auth failed, 1 attempts): user=<correo>, method=PLAIN, rip=192.168.4.153, lip=192.168.4.80, mpid=21286 What are we doing wrong?

Hello, I current using dovecot 2.0.11 and with all other 2x versions occurring the same problem. When i create the file .dovecot.sieve and compiled one .dovecot.svbin on user homedir, the imap show it like a folder, example: doveadm mailbox list -u user(a)domain.com .. .. *dovecot.sieve* *dovecot.svbin* .. .. I current using maildir and mail location is: *mail_location = maildir:%h:INDEX=%h/cache* Any tip to hide this to users? Sorry for my bad english :) Att. Francisco Freire System Administrator

[Dovecot] trying to combine static userdb with LDAP passdb with per-user userdb_mail and userdb_home
by Igor Zinovik 12 Apr '11

12 Apr '11

Hello, dovecot users. I'm trying to cope with following problem I have single computer which will be going to be final destination for several virtual domains. Domains are stored in LDAP catalog. Dovecot will be working together with Postfix MTA running on same computer. I'm a bit confused how to achieve following thing: I want Postfix to use Dovecot LMTP server for mail delivery. All my mail is located under /var/vmail partition. I designed my own ldap schema and according to dovecot documentation that user should always has home and mail directory i added separate attributes for user home and mail. My typical user that is stored in LDAP has homeDirectory (which stores value like /var/vmail/domain.com/j/joe) and mailMessageStore (which stores value like /var/vmail/domain.com/j/joe/Maildir). All data under /var/vmail is owned by Postfix MTA user (which is called `postfix', uid=89). After reading dovecot documentation I understand that my setup needs to combine static userdb with LDAP passdb. But i also want dovecot to be able to deliver mail for local system users (that are stored in /etc/passwd). For system users i want to store their mail in $HOME/Mail. So i set mail_location = ~/Mail (which turns into /home/user/Mail), but for virtual (which are stored in LDAP) users i want to set mail (or maybe i should write here userdb_mail) to LDAP value mailMessageStore. Seems to me that LMTP server needs separate userdb query to fetch mail_location from LDAP. Setting mail_location = /var/vmail/%d/%n1/%u solves my problem, but I want dovecot to dynamically fetch maildir location from LDAP. Maybe in near future I would also store mail somewhere else not only under /var/vmail. And dovecot will fetch this information from LDAP. Here is excerpt from dovecot log when user tries to login: Apr 11 13:32:29 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Apr 11 13:32:29 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Apr 11 13:32:29 auth: Debug: auth client connected (pid=14748) Apr 11 13:32:29 auth: Debug: client in: AUTH 1 PLAIN service=imap lip=172.20.21.26 rip=172.20.20.216 lport=143 rport=1227 resp=<hidden> Apr 11 13:32:29 auth: Debug: ldap(joe(a)domain.com,172.20.20.216): pass search: base=pdomain=domain.com,ou=mail,dc=org,dc=ru scope=onelevel filter=(&(objectClass=mailAccount)(uid=joe)(accountStatus=TRUE)) fields=mail,userPassword,mailQuota,homeDirectory,mailMessageStore Apr 11 13:32:29 auth: Debug: ldap(joe(a)domain.com,172.20.20.216): result: mail(user)=joe(a)domain.com mailQuota(userdb_quota_rule=*:bytes=%$)=1073741824 mailMessageStore(userdb_mail)=/var/vmail/domain.com/p/joe/Maildir homeDirectory(userdb_home)=/var/vmail/domain.com/p/joe userPassword(password)=<hidden> Apr 11 13:32:29 auth: Debug: client out: OK 1 user=joe(a)domain.com Apr 11 13:32:29 auth: Debug: master in: REQUEST 2814377985 14748 1 5e00190b4fbfd1a4b8a50e13fa6562b1 Apr 11 13:32:29 auth: Debug: master out: USER 2814377985 joe(a)domain.com uid=89 gid=89 Apr 11 13:32:29 imap-login: Info: Login: user=<joe(a)domain.com>, method=PLAIN, rip=172.20.20.216, lip=172.20.21.26, mpid=14750 Apr 11 13:32:29 imap: Debug: Loading modules from directory: /usr/lib64/dovecot Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib11_imap_quota_plugin.so Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib11_trash_plugin.so Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_autocreate_plugin.so Apr 11 13:32:29 imap: Debug: Module loaded: /usr/lib64/dovecot/lib20_expire_plugin.so Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Effective uid=89, gid=89, home= Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota root: name=User quota backend=maildir args= Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota warning: bytes=1020054732 (95%) messages=0 reverse=no command=/usr/libexec/dovecot/quota-warning.sh 95 joe(a)domain.com domain.com Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota warning: bytes=966367641 (90%) messages=0 reverse=no command=/usr/libexec/dovecot/quota-warning.sh 90 joe(a)domain.com domain.com Apr 11 13:32:29 imap(joe(a)domain.com): Debug: Quota warning: bytes=858993459 (80%) messages=0 reverse=no command=/usr/libexec/dovecot/quota-warning.sh 80 joe(a)domain.com domain.com Apr 11 13:32:29 imap(joe(a)domain.com): Error: user joe(a)domain.com: Initialization failed: Initializing mail storage from mail_location setting failed: Home directory not set for user.

Should i just add two attributes to each LDAP user like mailuid and mailgid and set both these variables to `postfix'. Or maybe i should just forget about mail for local system users and just user `prefetch' userdb. I'm just mazed about dovecot userdb and passdb queries. It so powerful but also so hard to understand. I would appreciate any help, since I peck dovecot authentication and userdb-passdb queries like woodpecker starting from last week. Do I understand right that dovecot during userdb fetches Unix UID which will be used to access data on disk? I just want postfix (uid=89) to allow to do this.

Re: [Dovecot] IO rate quotas?
by Alan Brown 12 Apr '11

12 Apr '11

From: Timo Sirainen <tss(a)iki.fi> Subject: Re: [Dovecot] IO rate quotas? > So a single process that is reading files fast enough from disk can > cause disk IO to spike in a way that makes all other processes wait for > available disk IO? It's not a single process. Thunderbird's newest defaults are to syncronize every folder and it will open one connectrion per folder in order to do that. Appropriate disk/swappiness/readahead/cache tuning is required - along with enough ram to cope with several users trying this at once. The underlaying filesystem is also important. as a for-instance, this kind of load with maildir format will effectively _kill_ a GFS box. Our fix was to install systemwide defaults on managed systems to not synchronize (not needed, the home directories are on network storage anyway) and to ask people to check/unset this on laptops/etc

[Dovecot] INBOX empty after dsync
by Gary Chodos 11 Apr '11

11 Apr '11

After hearing so many good things about mdbox, I am testing it. I moved my Maildir to a test box, and did the conversion with dsync which reported no errors and appeared to go fine after I set: namespace { separator = / inbox = yes } and changed mail_location=mdbox:~/mdbox But the problem is that the Inbox now is empty in my imap client. What did I do wrong? I can see the emails are there if I grep for subject lines I know exist in my inbox within ~/mdbox, but in the imap client it is as if inbox is totally empty. All the other folders appear fine in imap client.
