What other pluggable authentication plugins would you like in MariaDB?

MariaDB has had pluggable authentication since MariaDB 5.2. Our most popular authentication plugin that we ship in MariaDB is the PAM authentication plugin. Naturally one is curious to see if users would like to see more authentication plugins being made available, so we’ve posted a poll on Facebook. Please feel free to add your vote to the poll so we have a better idea of where to focus our future pluggable authentication development.
