First attempt to create a Radius authentication plugin. If the credentials are correct users are forwarded to their profile page, else they are forwarded to the registration page. I use it in conjunction with the sliding login plugin. Any comments are welcome!

Due to popular demand:This plugin will allow you to validate user credentials against a Radius server instead of the usual built-in Elgg user authorisation. This is usefull in case your Elgg installation is for instance on a intranet site of a company which has a large ICT department that already handles the creation of user account, deleting account, etc. This way only employees of that company with valid credentials will be able to log in. Therefore this plugin will not be usefull for most users as most companies still use LDAP for this.
