mount.cifs w/ sec=krb5i still non-op when DC != Fileserver

Folks,

this one relates to two threads from October 2009 - I ran into the same
problem with a Red Hat 5.5 beta kernel (2.6.18-186) and Samba packages
(3.3.8-0.50). Same symptoms as in
http://lists.samba.org/archive/linux-cifs-client/2009-October/005391.html
(Required key not available). 

Has any progress been made on this which Red hat could "easily" include in an
update kernel?

TIA!
