A newer version for WP3.0 is in the works. I would have loved to release it on time for the release of 3.0 but I’m having my finals at the moment so it will have to wait until June 2010. Will include single sign-on as well.
This plugin is for WordPress MU
This plugin basically allows you to host blogs on multiple domain names while maintaining one main site.
For example, the main site could be example.com but users will also be able to sign up for blogs on example.net, example.org or any other domain name that you choose to add.
<ul>
<li>All the sites will have the same settings</li>
<li>No extra blogs/tables are created for the additional domain names</li>
<li>All blogs will be viewable on the Site Admin blog list</li>
</ul>

You will have to login with your WordPress.org username and password to access these.
<h3>Known Issues/Limitations</h3>
<ul>
<li>Remote login does not work with this version</li>
<li>Only tested with VHOST installs in root directory</li>
</ul>

After testing all of the AJAX plugins in the WordPress repository, I got frustrated. They’re all great, but it seems that they’re like 90% complete. They still need polishing. This is why I decided to create this plugin
How is this plugin different:
<ul>
<li>Three different templates to choose from: Modal login form, Classic login form and popup login form (jQuery UI based)</li>
<li>24 themes to choose from (jQuery UI based) </li>
<li>Fully customizable: Just copy the template you’re using from /templates/ directory in the plugin to the “ultimate_ajax_login” directory in your theme, and modify as you need to.</li>
<li>After a user is logged in, nothing shows up. I found this pretty frustrating with other plugins, there was no way to hide things.</li>
<li>If you need to show anything after a user logs in, just copy the template widget-logged-in.php to your ultimate_ajax_login folder and add whatever you need. You can call any WP function from there.</li>
<li>Has three templates, one an AJAX-based classic login form, and the other is a jQuery UI dialog box (Tested and works on mobile), and the third one is a popmodal dialog box</li>
<li>Blocks the login form whenever a user is being logged in.</li>
<li>Allows you to specify a global login redirect URL in your settings page, which applies to all of your widgets.</li>
<li>Login redirect URL can be overridden on a per-widget basis from the widget options page.</li>
</ul>
Shortcode Usage
Instead of using the widget, you can insert the shortcode inside any post. If you’re a theme developer, you can use it with the do_shortcode() function. Here are the varius option
<ul>
<li>Using with classic template and no redirect url specified: [ultimate_ajax_login] </li>
<li>Using the dialog box template: [ultimate_ajax_login template=’dialog’]</li>
<li>Using the dialog box template and a jquery theme: [ultimate_ajax_login template=’dialog’ theme=’cupertino’]</li>
</ul>

Ultimate AJAX Login

Very flexible and easy to use AJAX Login plugin with redirects, customizable templates...
