samba - Aug 2007 - Mapping external MIT K5 realm users to windows domain users using winbindd

Is there a way to map a user from an external MIT K5 realm to a user in 
windows AD? 

We have a windows AD domain with a trust to an MIT K5 realm.  I am 
logged on to a workstation in the AD domain with an account from the MIT 
realm.  When I go to access the share a logon window pops up.  Even if I 
use the domain account the k5 ticket I have causes a logon failure.  
Because samba first tries the kerberized exchange which is valid because 
of the trust.  However because the user is from the realm and not the 
domain winbindd does not return a name.

Thanks for any help

Mark
