In my SPS2003 environment, the users are imported from Active
directory.

So, when a user is deleted from Active Directory, the next import
to the profile database will not delete his profile. It will only
mark it as
"Missing from Import" (and make it appear in the "Missing from
Import" view).
The profile is still searchable for the users.

Is there a way to retrieve all these missing import user profiles
programmatically?
