JS of English has completed installation of a multisite WordPress instance to accommodate course blogs in various English courses. The major issue with this project is authenticating students through LDAP, so I've been in contact with Corey S. I've downloaded and glanced through the documentation for two LDAP plugins for WordPress: 1) "simple ldap login" plugin at http://wordpress.org/extend/plugins/simple-ldap-login/ (Seems to be the most commonly used wp ldap plugin). 2) "WPMU LDAP" plugin you found at http://wpmuldap.tuxdocs.net/ Corey says "there are 2 types of LDAP groups we'll need to investigate, static or dynamic. I'll bet both plugins are looking for static group membership." So, next thing is to try to figure out in the source code whether each of the plugins supports both types of LDAP groups.
