If you're using PAP (which I guess is most likely if it's MAC
auth), you should be able to do something like

DEFAULT   User-Name =~ "^94ebcd", User-Password =~ "^94ebcd", Auth-Type := Accept

Or, depending on the number of prefixes, forget the users file and
just write it in unlang; maybe something like.

  if ( User-Name =~ /^94ebcd......$/ ) {
    update control {
      Cleartext-Password := "%{User-Name}"

Be very careful with that one for obvious reasons...

If you're doing CHAP (or something that needs the full cleartext
password) then you're probably limited anyway, as the only way
you're going to get the right cleartext password from a username
in a range when you don't list them all is to refer to said
