The problem we've had in the past (NT4 Domain) is that some
'domain accounts' do not show up as having logged in (from
the domain admins POV) because they never log in to the
domain directly. They are quite active with LDAP binds,
Exchange POP logins, etc. which are back ended to the domain.
While the Domain 'bad attempt lockout' policy applies to
these various logins, admins could not find a central place
to see 'account activity'. Is there a central place under AD
where you can find that a successful authentication has taken
place from ANY client against the domain credentials?

A related problem: in Oracle, there is a web-based interface
to various facilities, but you can also access mail via standard
mechanisms such as IMAP.  If you never use the web-based
interface (collab suite) then you never see the messages warning
you that your password is about to expire or that your password
*has* expired and you should now change it.  Instead your email
simply stops working and generates a call to the help desk.

The larger the site, the more people who don't use the web
interface, and the more helpdesk calls are generated for something
that users should have taken care of themselves.  The risk from
this is that the easiest fix is simply to disable password
expiry.
