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.

René Cannaò	c3e6fda7a4	Track and handle autocommit (#438) ... - MySQL_Session::handler_special_queries() processes set autocommit from clients - to the client is always returned the autocommit value set in the session - set autocommit is either just acknowledged to the client, or forwarded to the backend based on the status of transactions - unless there are query rules to handle SET AUTOCOMMIT , the statement is forwarded to the first found active transaction: this assumes there is just one transactions. Although multiple transactions are possible, handling multiple transactions at the same time seems a dangerous adventure	10 years ago
