- # For the sql passdb module, you'll need a database with a table that
- # contains fields for at least the username and password. If you want to
- # use the user@domain syntax, you might want to have a separate domain
- # field as well.
- #
- # If your users all have the same uig/gid, and have predictable home
- # directories, you can use the static userdb module to generate the home
- # dir based on the username and domain. In this case, you won't need fields
- # for home, uid, or gid in the database.
- #
- # If you prefer to use the sql userdb module, you'll want to add fields
- # for home, uid, and gid. Here is an example table:
- #
- # CREATE TABLE users (
- # username VARCHAR(128) NOT NULL,
- # domain VARCHAR(128) NOT NULL,
- # password VARCHAR(64) NOT NULL,
- # home VARCHAR(255) NOT NULL,
- # uid INTEGER NOT NULL,
- # gid INTEGER NOT NULL,
- # active CHAR(1) DEFAULT 'Y' NOT NULL
- # );
- # Database driver: mysql, pgsql, sqlite
- #driver =
- # Database connection string. This is driver-specific setting.
- #
- # pgsql:
- # For available options, see the PostgreSQL documention for the
- # PQconnectdb function of libpq.
- #
- # mysql:
- # Basic options emulate PostgreSQL option names:
- # host, port, user, password, dbname
- #
- # But also adds some new settings:
- # client_flags - See MySQL manual
- # ssl_ca, ssl_ca_path - Set either one or both to enable SSL
- # ssl_cert, ssl_key - For sending client-side certificates to server
- # ssl_cipher - Set minimum allowed cipher security (default: HIGH)
- # option_file - Read options from the given file instead of
- # the default my.cnf location
- # option_group - Read options from the given group (default: client)
- #
- # You can connect to UNIX sockets by using host: host=/var/run/mysqld/mysqld.sock
- # Note that currently you can't use spaces in parameters.
- #
- # MySQL supports multiple host parameters for load balancing / HA.
- #
- # sqlite:
- # The path to the database file.
- #
- # Examples:
- # connect = host=192.168.1.1 dbname=users
- # connect = host=sql.example.com dbname=virtual user=virtual password=blarg
- # connect = /etc/dovecot/authdb.sqlite
- #
- #connect =
- # Default password scheme.
- #
- # List of supported schemes is in
- # http://wiki.dovecot.org/Authentication/PasswordSchemes
- #
- #default_pass_scheme = PLAIN-MD5
- # passdb query to retrieve the password. It can return fields:
- # password - The user's password. This field must be returned.
- # user - user@domain from the database. Needed with case-insensitive lookups.
- # username and domain - An alternative way to represent the "user" field.
- #
- # The "user" field is often necessary with case-insensitive lookups to avoid
- # e.g. "name" and "nAme" logins creating two different mail directories. If
- # your user and domain names are in separate fields, you can return "username"
- # and "domain" fields instead of "user".
- #
- # The query can also return other fields which have a special meaning, see
- # http://wiki.dovecot.org/PasswordDatabase/ExtraFields
- #
- # Commonly used available substitutions (see http://wiki.dovecot.org/Variables
- # for full list):
- # %u = entire user@domain
- # %n = user part of user@domain
- # %d = domain part of user@domain
- #
- # Note that these can be used only as input to SQL query. If the query outputs
- # any of these substitutions, they're not touched. Otherwise it would be
- # difficult to have eg. usernames containing '%' characters.
- #
- # Example:
- # password_query = SELECT userid AS user, pw AS password \
- # FROM users WHERE userid = '%u' AND active = 'Y'
- #
- #password_query = \
- # SELECT username, domain, password \
- # FROM users WHERE username = '%n' AND domain = '%d'
- # userdb query to retrieve the user information. It can return fields:
- # uid - System UID (overrides mail_uid setting)
- # gid - System GID (overrides mail_gid setting)
- # home - Home directory
- # mail - Mail location (overrides mail_location setting)
- #
- # None of these are strictly required. If you use a single UID and GID, and
- # home or mail directory fits to a template string, you could use userdb static
- # instead. For a list of all fields that can be returned, see
- # http://wiki.dovecot.org/UserDatabase/ExtraFields
- #
- # Examples:
- # user_query = SELECT home, uid, gid FROM users WHERE userid = '%u'
- # user_query = SELECT dir AS home, user AS uid, group AS gid FROM users where userid = '%u'
- # user_query = SELECT home, 501 AS uid, 501 AS gid FROM users WHERE userid = '%u'
- #
- #user_query = \
- # SELECT home, uid, gid \
- # FROM users WHERE username = '%n' AND domain = '%d'
- # If you wish to avoid two SQL lookups (passdb + userdb), you can use
- # userdb prefetch instead of userdb sql in dovecot.conf. In that case you'll
- # also have to return userdb fields in password_query prefixed with "userdb_"
- # string. For example:
- #password_query = \
- # SELECT userid AS user, password, \
- # home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid \
- # FROM users WHERE userid = '%u'
- driver = mysql
- connect = host=localhost dbname=postfix user=postfix password=paasword
- default_pass_scheme = MD5-CRYPT
- user_query = SELECT '/var/vmail/%d/%n' as home, 'maildir:/var/vmail/%d/%n' as mail, 150 AS uid, 8 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = 1
- password_query = SELECT username as user, password, '/var/vmail/%d/%n' as userdb_home, 'maildir:/var/vmail/%d/%n' as userdb_mail, 150 as userdb_uid, 8 as userdb_gid FROM mailbox WHERE username = '%u' AND active = 1
