Inactive - does not take up a license, and can not login to the database. Can be reactivated at a later date. This is a good option if someone doesn't need access for an extended period of time. Also, this is good to use instead of deleting a user. When deleting a user, you must reassign everything to a new user. By making them inactive, you can see everything the old user did, but they can't login and it does not take up a license.
Active Pending Logon - This means a login name has been created, but that user has not logged in yet. Once they do, it will take up a license
Activie - user has logged into the database at least once and they are taking up a license.
Hope this helps.
