The best thing to do is either have the password file regenerated, or compare active members to the ones in your htpasswd file. Those usernames in htpasswd that aren't on the active member list can be manually removed.

I do the compare with a Word macro, but any script junkie can create a grep shell command and you can probably do it right on the server.
