That may be true, but there is another win in this type of environment.
Separation of your authentication database from your identity management
database. Regardless of how you authenticate in this scenario, you will
be sending passwords (even encrypted) over the wire. If the passwords
are in a KDC then at least it's not easy to gain those passwords. If you
keep your passwords in LDAP, then you need to be very careful about who
has access to them.
