I spent some time updating all of my WordPress plugins today.  A few months ago commenter Bramus noted that Simple LDAP Login allowed all WordPress users, regardless of rights, to access the administrative page.  I took an appalling amount of time to get around to updating this, but I went ahead and updated it in all of my plugins. (Those with admin pages)

I also fixed a couple of other minor issues that hardly merit mention. 

If you are using these plugins, I suggest you go ahead and update.
