[Dovecot] dovecot auth ldap attributes - unused?
by Maciej Uhlig 21 May '14

21 May '14

Please explain the following dovecot (2.2.13) behaviour: I run dovecot in ldap auth debug mode and log file excerpt follows: 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): bind search: base=o=tree,dc=do,dc=ma,dc=in filter=(&(objectClass=MailAccount)(accountActive=TRUE)(mail=user@domain)) 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): result: mail=user@domain; mail unused 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): result: mail=user@domain 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: client passdb out: OK 24 user=user@domain 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): user search: base=o=tree,dc=do,dc=ma,dc=in scope=subtree filter=(&(objectClass=MailAccount)(accountActive=TRUE)(mail=user@domain)) fields=mail,quota,mailbox 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): result: mailbox=maildir:/mail/domain/user/mail/ quota=1G mail=user@domain; mail,mailbox,quota unused 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: ldap(user@domain,pcip,<bdKvA+P5HQCbnmFI>): result: mailbox=maildir:/mail/domain/user/mail/ quota=1G mail=user@domain 2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: master userdb out: USER 3606315009 user@domain quota_rule=*:bytes=1G mail=maildir:/mail/domain/user/mail/ home=/mail/domain/user Question: why are there two ldap result log lines while the first line shows unused attributes and the second doesn't. Does the first occurence show some code being excessive somehow? Thanks. MU

[Dovecot] allow_nets + default + ldap
by Andreas Schulze 21 May '14

21 May '14

Hello, I'm playing with allow_nets function. It is really cool! In a filebased passwd backend you simply add "allow_nets=192.0.2.143/32" as mentioned in http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/AllowNets But if I use an LDAP backend it looks different. Following http://wiki2.dovecot.org/AuthDatabase/LDAP/AuthBinds and http://wiki2.dovecot.org/AuthDatabase/LDAP/Userdb#Attribute_templates_.28v2… my pass_attrs looks this: pass_attrs = =user=%{ldap:uid}, \ =allow_nets=%{ldap:allownets} Using this syntax I could add an attribute "allownets" in the ldapserver to limit access for a user. A problem occour if the attribute is not present. For example if a user should not be limited or only some but not any user should be limited. So I extend my pass_attrs with a default. pass_attrs = =user=%{ldap:uid}, \ =allow_nets=%{ldap:allownets:10.0.0.0/8} Again, that's fine. Any user was allowed to connect from my private network. But then some users connect via ipv6. I tried to extend my default to pass_attrs = =user=%{ldap:uid}, \ =allow_nets=%{ldap:allownets:10.0.0.0/8,fec0::/16} That syntax, a comma separated list, produces errors no matter if quoting using " or ' or no quoting at all. So I looked at the source (thanks, it's open!) and wrote a little patch to allow simple defaults: - ALL -> allow any address - NONE -> deny any address Now I could write pass_attrs = =user=%{ldap:uid}, =allow_nets=%{ldap:allownets:ALL} or pass_attrs = =user=%{ldap:uid}, =allow_nets=%{ldap:allownets:NONE} to allow or deny any ldap account not having an attribute allownets. Maybe there are other solutions, but that's my way... Andreas

Trying to figure out the syntax to set a mail_location for SQL. This doesn't work: userdb { driver = sql args = /etc/dovecot/master-combined-sql.conf override_fields = mail_location=maildir:/fakedir/%d/%n:INBOX=/fakedir:LAYOUT=fs } Does anyone know the proper syntax? Thanks in advance

[Dovecot] Dict SQL lookups without username_field
by Andrew Beverley 20 May '14

20 May '14

Dear all, Is it possible to perform dict lookups with a SQL backend, without specifying the username_field in the SQL query? I am using the dict to retrieve a Sieve script. My dict configuration looks like this: map { pattern = priv/sieve/data/$id table = sieve_scripts username_field = email value_field = data fields { id = $id } } I don't want to specify the username though, as the sieve scripts are valid for all users. However, when I remove "username_field" I get the error "data with id `1' for script `main script' not found at path priv/sieve/data/1" Thanks, Andy

[Dovecot] Performing an action on mail receipt
by Andrew Beverley 20 May '14

20 May '14

Dear all, I would like to perform an action for certain users each time a mail arrives via LMTP. I would like to send an email notification to an external email address when new mail has arrived for certain users (note: not a forward). I am assuming that creating my own plugin using the existing "notify" plugin is the way to go. However, before I go down that route, I'd like to check that is the best approach? Or would it be better to perform this sort of thing before the mail reaches Dovecot? Assuming writing a plugin is answer, do they have to be written in C? Dovecot version: 2.1.7 Thanks, Andy

|Hi list, If I've added the tika stuff to my tomcat/solr setup, ie copied: | ||solr-4.7.2/dist/solr-cell-*| solr-4.7.2/contrib/extraction/lib/* to ||/var/lib/tomcat6/webapps/solr/WEB-INF/lib/ how do I get dovecot to index attachments? Do I just need to add| fts-solr =/index-attachments url=http://localhost:8080/solr-4.7.2/ /to the 90-plugin.conf? Or do I need to so something like fts_tika =/http://localhost:8080/solr-4.7.2// IE the same uri I have for the solr? Thanks Alex

20 May '14

Hi list, im trying to build a web based system for secure communication build with standard linux software, instead of using CMS based systems. One of the requirements is to send notifications to users when receiving mail. Can a script find information about the mail address of received mails in dovecot logs or is there a better way. -seeberg

[Dovecot] Dovecot 2.2.13+ and master user db
by Juan C. Blanco 20 May '14

20 May '14

Hello, I'm upgrading one of our servers to the last HG 2.2.13 versión and I've found some problems with our configuration which has been working fine with previous versions. We have a LDAP userdb for the users and a master userdb for user assistance, Until now the definition of usersdb in 10-auth.conf was: !include auth-master.conf.ext !include auth-system.conf.ext !include auth-ldap.conf.ext With the 2.2.12 version this worked fine but with 2.2.13+ version the LDAP users can't login in dovecot (IMAP), however the master users can login fine. However, if I comment out the master userdb or change the order, i.e. !include auth-system.conf.ext !include auth-ldap.conf.ext !include auth-master.conf.ext In this case LDAP and master users can login normally. Is this configuration change required for the new version or it's a bug? Follows the log sections for both configurations Regards Juan C. Blanco There is the log for the first case (master before ldap) with debugging activated: May 20 08:57:43 master: Info: Dovecot v2.2.13 starting up for imap, pop3, lmtp, sieve (core dumps disabled) May 20 08:57:51 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth May 20 08:57:51 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so May 20 08:57:51 auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth May 20 08:57:51 auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so May 20 08:57:51 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat May 20 08:57:51 auth: Debug: passwd-file /nas/mail/etc/passwd.master: Read 1 users in 0 secs May 20 08:57:51 auth: Debug: auth client connected (pid=22482) May 20 08:57:56 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=T/5QZs/54gB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=56290 resp=<hidden> May 20 08:57:56 auth: Debug: ldap(user1,127.0.0.1,<T/5QZs/54gB/AAAB>): cache miss May 20 08:57:56 auth: Debug: ldap(user1,127.0.0.1,<T/5QZs/54gB/AAAB>): bind search: base=dc=some,dc=domain,dc=es filter=(uid=user1) May 20 08:57:56 auth: Debug: ldap(user1,127.0.0.1,<T/5QZs/54gB/AAAB>): result: Mailbox=/mail/user1 MailQuotaSize=10240; Mailbox,MailQuotaSize unused May 20 08:57:56 auth: Debug: ldap(user1,127.0.0.1,<T/5QZs/54gB/AAAB>): result: Mailbox=/mail/user1 MailQuotaSize=10240 May 20 08:57:56 auth: Debug: client passdb out: OK 1 user=user1 May 20 08:57:56 auth: Debug: master in: REQUEST 4005167105 22482 1 f14d67dfcbfd5fdffe206fba32ef320b session_pid=22485 request_auth_token May 20 08:57:56 auth: Debug: passwd-file(user1,127.0.0.1,<T/5QZs/54gB/AAAB>): userdb cache miss May 20 08:57:56 auth: Debug: passwd-file(user1,127.0.0.1,<T/5QZs/54gB/AAAB>): lookup: user=user1 file=/nas/mail/etc/passwd.master May 20 08:57:56 auth: Info: passwd-file(user1,127.0.0.1,<T/5QZs/54gB/AAAB>): unknown user May 20 08:57:56 auth: Debug: prefetch(user1,127.0.0.1,<T/5QZs/54gB/AAAB>): success May 20 08:57:56 auth: Debug: master userdb out: USER 4005167105 user1 auth_token=51719362e64e34996d44dfbde00993c989be6580 May 20 08:57:56 imap-login: Info: Login: user=<user1>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=22485, secured, session=<T/5QZs/54gB/AAAB> May 20 08:57:56 imap: Debug: Loading modules from directory: /usr/lib64/dovecot May 20 08:57:56 imap: Debug: Module loaded: /usr/lib64/dovecot/lib01_acl_plugin.so May 20 08:57:56 imap: Debug: Module loaded: /usr/lib64/dovecot/lib02_imap_acl_plugin.so May 20 08:57:56 imap: Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so May 20 08:57:56 imap: Debug: Module loaded: /usr/lib64/dovecot/lib11_imap_quota_plugin.so May 20 08:57:56 imap: Debug: Added userdb setting: plugin/=yes May 20 08:57:56 imap(user1): Debug: Effective uid=98, gid=12, home= May 20 08:57:56 imap(user1): Debug: Quota root: name=User quota backend=maildir args= May 20 08:57:56 imap(user1): Debug: Quota rule: root=User quota mailbox=* bytes=10485760 messages=0 May 20 08:57:56 imap(user1): Debug: Quota rule: root=User quota mailbox=Trash bytes=+1048576 (10%) messages=0 May 20 08:57:56 imap(user1): Debug: Quota warning: bytes=9961472 (95%) messages=0 reverse=no command=quota-warning 95 user1 May 20 08:57:56 imap(user1): Debug: Quota warning: bytes=8388608 (80%) messages=0 reverse=no command=quota-warning 80 user1 May 20 08:57:56 imap(user1): Debug: Quota grace: root=User quota bytes=1048576 (10%) May 20 08:57:56 imap(user1): Debug: Namespace inbox: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir May 20 08:57:56 imap(user1): Error: user user1: Initialization failed: Namespace '': Home directory not set for user.
