Active Directory Authentication Integration vs wpDirAuth

This plugin allows WordPress to authenticate, authorize, create and update against an Active Directory domain. This plugin is based heavily on the Active Directory Integration plugin, but has been modified to work with Multi Site and even Multi Network installations of WordPress. Some of the features included in this plugin are: authenticate against more than one AD Server (for balanced load) authorize users by Active Directory group memberships auto create and update users that can authenticate against AD mapping of AD groups to WordPress roles use TLS (or LDAPS) for secure communication to AD Servers (recommended) use non standard port for communication to AD Servers protection against brute force attacks user and/or admin e-mail notification on failed login attempts determine WP display name from AD attributes (sAMAccountName, displayName, description, SN, CN, givenName or mail) enable/disable password changes for local (non AD) WP users WordPress 3.0/3.1 compatibility, including Multi Site and Multi Network This plugin is based on glatze’s Active Directory Integration plugin, which is based upon Jonathan Marc Bearak’s Active Directory Authentication plugin and Scott Barnett’s adLDAP, a very useful PHP class. Aside from the changes to make this plugin work more effectively with WordPress Multi Site, this version of the plugin also encrypts the password used to connect to the AD server when it is stored in the database. This plugin was developed by Curtiss Grymala for the University of Mary Washington. It is licensed under the GPL2, which basically means you can take it, break it and change it any way you want, as long as the original credit and license information remains somewhere in the package. Important Notice Since I don’t currently have access to multiple AD servers, this plugin has only been tested on a single installation of WordPress with a single AD server. Therefore, it is entirely possible that there are major bugs. At this time, I am seeking people to test the plugin, so please report any issues you encounter. Requirements This plugin requires WordPress. It might work with versions older than 3.0, but it has not been tested with those. This plugin also requires PHP5. Some attempt has been made to make it compatible with PHP4, but it has not been tested in that environment. This plugin requires LDAP support to be compiled into PHP. If the ldap_connect() function is not available, this plugin will output an error message and will not do anything. To Do Add ability to validate against multiple AD servers (check one, then the other – rather than just load-balancing as the plugin currently does) DONE as of 0.4a – Update admin interface to utilize native meta box interface rather than custom layout DONE as of 0.3a – Separate the profile information from the role equivalent groups in the “auto update user” setting

Please see the Changelog (Development tab above) for recent updates/changes. wpDirAuth shifts authentication from the local WordPress instance to a central directory (LDAP) server(s). wpDirAuth allows users of central directory (LDAP) servers to login to authorized WordPress instances without having to register. The plugin creates a new account for each directory user on first login so that they have full access to preferences and functions, as any WP user would. Activating the plugin will not restrict you to using directory authentication and you will still be able to both create new WP-only users as well as turn on public registration in WordPress. You can also assign any privilege levels to your directory users, and the those users will be referred to their institutional password policy whenever they would normally able to update their WP passwords (on the profile screen, in user edit, etc). LDAP/LDAPS Authentication should work with most LDAP enabled directory services, such as OpenLDAP, Apache Directory, Microsoft Active Directory, Novell eDirectory, Sun Java System Directory Server, and more. wpDirAuth supports LDAP and LDAPS (SSL) connectivity and can force SSL for WordPress authentication if it is available on the Web server. It also supports server connection pools, for pseudo load balancing and fault tolerance, or multiple source directory authentication. Because the key used to locate a user’s profile in the LDAP server is not always the same, depending on your LDAP server type and institutional choices, you can define your own through the wpDirAuth administration tool. When logging in as a directory user, the WP “remember me” feature is downgraded from 6 months for regular WP users to only 1 hour, so that institutional passwords are not overly endangered when accessing WP from public terminals. Branding & Notifications You can define notifications addressed to your directory users in key WordPress areas, such as the login screen and the profile edit screen. Since these admin-editable values support HTML (admin, coders, beware of xss!), you can point your directory users to central support information related to functions such as changing their institutional password, a WordPress usage related policy, etc. There is also a simple and optional terms of services concept, only implemented for directory users, which will simply record a one-time acceptance date when agreed upon. Note that agreeing to the TOS has no effect on the user’s level of access in the system, fact which could change in future version if there is a demand for it, or through direct code contribution to that effect. Using wpDirAuth Once installed and activated, you will be able to administer your directory settings through the dedicated plugin configuration tool found under the wpDirAuth menu found in the WordPress Settings admin section. Directory Authenticated users can now be pre-added to your wordpress system and granted roles by going to the Add Dir Auth User menu found in the WordPress Users admin section. Contextual help for this section is available for this section within WordPress’ built-in help menu. See the inline help found in the tool for more information on the settings. There is a secondary activation toggle, so you can install and activate the plugin, check out the options panel, but not immediately accept directory authentication, or even simply turn the feature on or off at any time.

TO-DO’s Internationalization Refactor to a class More action/filter hooks Source and Development wpDirAuth welcomes friendly contributors wanting to lend a hand, be it in the form of code through SVN patches, user support, platform portability testing, security consulting, localization help, etc. The [current] goal is to keep the plugin self-contained (ie: no 3rd-party lib) for easier security maintenance, while keeping the code clean and extensible. Focus is on security, features, security, and let’s not forget, security. Unit tests will hopefully be developed and constant security audit performed. Recurring quality patch contributions will lead to commit privileges to the project source repository.
