Microsoft did document this, in the kerbsteps.asp file. look at the
"Setting Trust with a Kerberos Realm" section of

I set up a test network that did something like this awhile ago. It's
long gone, so I can't pull configs off it, but here's what I remember
from my notes: (it appears the same as what's at the URL I listed)

  the AD realm is WOFFICE, the kerberos realm is OFFICE

  the workstations need a krb5.conf equivlent entry for OFFICE, use
  ksetup /addkdc to make it.

  the realms need a shared key (I think)

  each account needs a mapping account mapping between the realms. use
  "Active Directory Users and Computers" to map foo at WOFFICE to
  foo at WOFFICE

  the workstation's login screen will have 2 realms. the kerberos one,
  and the AD one. Users shouldn't know the passwords in the AD realm,
  and if they select the kerberos one all the right things
  happen. (they can also just login as foo at OFFICE, and it'll figure
  out the right realm)
