After a lot of reading and emailing, it comes down to this. libkrb5-3 version 1.8x by default disallows DES encryption. /etc/krb5.conf can be changed to allow weak encryption, but as it relates to Samba, is only effective in letting the system join the domain. For it's internal functioning, winbind uses an autogenerated krb5.conf that resides in /var/run/samba. This krb5.conf has no knowledge of allow_weak_crypto=true. Sam Hartman, the maintainer of libkrb5-3 in Debian, has taken over the responsibility of fixing that package, rather than the Samba maintainers doing a change there. In the interim, winbind is broken with libkrb5-3 version 1.8x. We can only hope this fix is soon coming. > > In Samba 3.5.0 there is a parameter "create krb5 conf" that controls > if this private krb5.conf file is created or not.

I'm assuming that samba/winbind would look at /etc/krb5.conf if the private one is not created. On the other hand, if libkrb5-3 is soon to be fixed, then all that work might not be necessary. Perhaps someone at Debian could inform us of the current status. I know that at one time, Christian Perrier was following this.
