Password synching

[Digant Kasundra]

Is anyone aware of any product that can sync passwords between an MIT
Kerberos KDC and MS Active Directory?

Is it even possible to "hook into" a password change event in Kerberos?  Can
that trigger an event or something of that sort?  I know that on the Windows
side, you would add a password filter that would be called during the
password change call and it would be used to make the change in external
systems like Kerberos.
