This commit is just a POC!
It hardcodes the mapping of frontend to backend usernames. Client can connect to ProxySQL with frontend credentials (username and password) and in case of successful authentication it will replace username with the mapped username. It will later retrieve the password using the backend username.
The mapping (and also the client authentication) will fail if the mapped username doesn't exist, or if the password of the mapped username is not in clear text.
Because the mapped password must be in clear text, variable
admin-hash_passwords
must be set tofalse
.Attributes like
default_hostgroup
,default_schema
, andtransaction_persistent
are all retrieved from the frontend user entry.Mapping is not supported for
COM_CHANGE_USER()
executed by client.
