Updated some of the labels on the options screen to make them a little more explanatory.
Fixed a critical bug that stopped the options from being saved in certain situations.
Updated options page to use HTML label elements properly for each field
Tested for compatibility with WordPress 3.2
Updated administrative user interface to use native WordPress metaboxes
Separated the option to append user suffixes during validation against the AD server and appending user suffixes to the WordPress account username (previously, if you appended user suffixes to the WordPress account username, that suffix was also used in the validation process; which caused validation to fail on some AD servers). There are now two separate setting for "WordPress account suffix" and "AD Account Suffix".
Updated the way "automatic user update" is handled. Previously, if you had automatic user update enabled, and you had role-equivalent settings configured, all users that matched those role-equivalent settings would be given those roles when they logged in; even if you had previously promoted a specific user to a higher WordPress role. You now have the option to enable that feature or not; separately from the setting that updates the user's contact information on login.
Updated the way scripts and styles are registered within the plugin
