René Cannaò	54d32d4580	Implementation of AUTH SWITCH ... - if clients uses mysql_native_password, if LDAP is enabled and if the user doesn't exist, switch to mysql_clear_password. - if neither mysql_native_password or mysql_clear_password are used by the client: - if LDAP is not enabled, always switch to mysql_native_password - if LDAP is enabled: - if the user exists, switch to mysql_native_password - if the user doesn't exists, switch to mysql_clear_password Added MySQL variable mysql-add_ldap_user_comment to determine if a comment with the original username needs to be added in the queries.
