By logging the password hash when user authentication fails due to a
password mismatch, we can be certain what the client sent and what is the
currently stored value in MaxScale. This should not be on by default which
is why a new parameter is required.
The release notes now mention that the caching is done by the
authenticators, not by the core. It also mentions that only MySQLAuth
implements this functionality.
Added notes to binlogrouter documentation about the changes to the loading
and storing of users.
Cleaned up MySQL-Authenticator document to make it a bit easier to read.
The MySQL authenticator now injects the service user into the list of
allowed users if loading of database users fails. This allows the removal
of common code in the binlogrouter and maxinfo modules.
The MySQLAuth authenticator can now store the cached credentials in a
custom location. This is intended for the binlogrouter, which currently
uses a different location for the user cache.
The MySQL authentication modules now have their own document in the
Authenticators directory. Right now this document only describes the
general details of the MySQL authentication and the new option.
