All:
Please find attached a patch that creates a separate krb5.conf file
during provision, instead of lumping it within the named.conf file that
is created.
Additionally, a small patch is included for the enableaccount script to
use the correct command name in the usage statement.
The patches have also been pushed to git://git.id10ts.net/samba.git, in
the v4-0-local branch.
Thanks,
Andrew
