Cross realm between AD and MIT

I found a solution (is it a good solution ?) :
- I add my client (W7) into my AD.MYREALM (Microsoft Domain)
- on the client, I do : ksetup /AddKdc MYREALM
As you see, I don't give the address of the MIT KDC. I can open a session
with a MIT KDC user.
If I do : ksetup /AddKdc MYREALM kdc1.myrealm, that does not work.
What do you think about it ?
