Many people use wordpress to run blogs alongside their Ruby on Rails applications. And many 
Ruby on Rails applications use very similar login systems, derived from the restful_authentication 
or clearance plugins. This plugin provides hooks so that your wordpress blog can read your rails 
app’s database.yml file, connect to that database and authenticate the user against your rails app.
This plugin requires the syck PHP extension for parsing yaml. Instructions for installing syck are available at 
http://trac.symfony-project.org/wiki/InstallingSyck
<h3>To Do</h3>
<ul>
<li>Add automated tests</li>
<li>Solicit user feedback on further options</li>
</ul>

Log users in against their accounts in a Ruby on Rails application.

This plugin will allow you to automatically rehash the passwords of users you have beforehand imported from a Magento database to your WordPress database.
This is useful if you are migrating a website from Magento to WordPress.
It allows users to authenticate via their email address, like on a Magento installation.
Upon login, the plugin will check the password entered by the user, against the value stored in the database. It’ll verify if the password is correct and, only in that case, it’ll rehash the password using WordPress’ default hashing algorithm and insert the new password to the database. Then it’ll try logging in.
In every other case, login will function normally, so if there is an error, it’ll be returned.
In a while, every former Magento user you have imported to your WP DB will have their passwords securely rehashed.
Tested successfully with Magento 1.8.0.0 and WordPress 3.7.1.
