# This file is commonly accessed via passdb {} or userdb {} section in # conf.d/auth-sql.conf.ext # This file is opened as root, so it should be owned by root and mode 0600. # # http://wiki2.dovecot.org/AuthDatabase/SQL # # 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. # # HA / round-robin load-balancing is supported by giving multiple host # settings, like: host=sql1.host.org host=sql2.host.org # # pgsql: # For available options, see the PostgreSQL documention for the # PQconnectdb function of libpq. # Use maxconns=n (default 5) to change how many connections Dovecot can # create to pgsql. # # mysql: # Basic options emulate PostgreSQL option names: # host, port, user, password, dbname # # But also adds some new settings: # client_flags - See MySQL manual # connect_timeout - Connect timeout in seconds (default: 5) # read_timeout - Read timeout in seconds (default: 30) # write_timeout - Write timeout in seconds (default: 30) # 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) # ssl_verify_server_cert - Verify that the name in the server SSL certificate # matches the host (default: no) # 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/mysql.sock # Note that currently you can't use spaces in parameters. # # 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://wiki2.dovecot.org/Authentication/PasswordSchemes # #default_pass_scheme = 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://wiki2.dovecot.org/PasswordDatabase/ExtraFields # # Commonly used available substitutions (see http://wiki2.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://wiki2.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' # Query to get a list of all usernames. #iterate_query = SELECT username AS user FROM users
