## Mysql Server

auth.mysql.server = 127.0.0.1:3306

## Mysql Pool Size
auth.mysql.pool = 8

## Mysql Username
## auth.mysql.username =

## Mysql Password
## auth.mysql.password =

## Mysql Database
auth.mysql.database = mqtt

## Variables: %u = username, %c = clientid

## Authentication Query: select password only
auth.mysql.auth_query = select password from mqtt_user where username = ‘%u’ limit 1

## Password hash: plain, md5, sha, sha256, pbkdf2
auth.mysql.password_hash = sha256

## %% Superuser Query
auth.mysql.super_query = select is_superuser from mqtt_user where username = ‘%u’ limit 1

## ACL Query Command
auth.mysql.acl_query = select allow, ipaddr, username, clientid, access, topic from mqtt_acl where ipaddr = ‘%a’ or username = ‘%u’ or username = ‘$all’ or clientid = ‘%c’
