+# For the mysql passdb module, you'll need a database with a table that
+# contains fields for at least the userid 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 userid and domain. In this case, you won't need fields
+# for home, uid, or gid in the database.
+#
+# If you prefer to use the mysql userdb module, you'll want to add fields
+# for home, uid, and gid. Here is an example table:
+#
+# CREATE TABLE users (
+#     userid VARCHAR(128) NOT NULL,
+#     password VARCHAR(64) NOT NULL,
+#     home VARCHAR(256) NOT NULL,
+#     uid INTEGER NOT NULL,
+#     gid INTEGER NOT NULL,
+#     active CHAR(1) DEFAULT 'Y' NOT NULL
+# );
+
+db_host = localhost
+db_port = 3306
+#db_unix_socket = /var/tmp/mysql.sock
+db = users
+db_user = dovecot-db
+db_passwd = opensesame
+db_client_flags = 0
+
+# Default password scheme.
+#
+# Currently supported schemes include PLAIN, PLAIN-MD5, DIGEST-MD5, and CRYPT.
+#
+#default_pass_scheme = PLAIN-MD5
+
+# Query to retrieve the password.
+#
+# The query should return one row, one column. If more than one row or column
+# is returned, authentication will automatically fail.
+#
+# Available substitutions:
+#   %u = entire userid
+#   %n = user part of user@domain
+#   %d = domain part of user@domain
+#
+# Example:
+#   password_query = SELECT password FROM users WHERE userid = '%n' AND domain = '%d'
+#   password_query = SELECT password FROM users WHERE userid = '%u' AND active = 'Y'
+#
+#password_query = SELECT password FROM users WHERE userid = '%u'
+
+# Query to retrieve the user information.
+#
+# The query must return only one row. The columns to return are:
+#   home - Home directory
+#   mail - MAIL environment
+#   system_user - System user name (for initgroups())
+#   uid - System UID
+#   gid - System GID
+#
+# Either home or mail is required. uid and gid are required. If more than one
+# row is returned or there's missing fields, login will automatically fail.
+#
+# Examples
+#   user_query = SELECT home, uid, gid FROM users WHERE userid = '%n' AND domain = '%d'
+#   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 userid = '%u'
