We have lately been talking about some upcoming features that we feel are important to MariaDB users, because the corresponding ones that will be provided with MySQL will be incompatible with MariaDB and closed source.
We’re happy to announce the following:
- The next version of MariaDB, version 5.2.10 will include an open source PAM Authentication Plugin. MariaDB 5.2.10 is scheduled for release next week.
- A Windows Authentication Plugin is in development and QA currently and will be part of MariaDB 5.2.11, which is scheduled for release before Christmas.
- MariaDB 5.5 will include both of the above plugins and an open source thread pool implementation.
As you may know, since version 5.2.0 (released in April 2010) we support Pluggable Authentication. Using this feature one can implement an arbitrary user authentication and account management policy, completely replacing built-in MariaDB authentication with its username/password combination and mysql.user table.
Also, as you might have heard, Oracle has recently released a PAM authentication plugin for MySQL. Alas, this plugin will not run on MariaDB — although the MySQL implementation of pluggable authentication is based on ours, the API is incompatible. And, being closed source, this plugin cannot be fixed to run in MariaDB. And — I’m not making it up — this plugin does not support communication between the client and the server, so even with this plugin and all the power of PAM the only possible authentication method remains a simple username/password combination. …
