Winbindd/Netlogon improvements
==============================
The whole concept of maintaining the netlogon secure channel
to (other) domain controllers is rewritten in order to maintain
global state in a netlogon_creds_cli.tdb. This is the proper fix
for a large number of bugs:

In addition a strong session key is required by default now,
which means that communication to older servers or clients
might be rejected by default.
For the client side we the following new options:
"require strong key" (yes by default), "reject md5 servers" (no by default).
E.g. for Samba 3.0.37 you need "require strong key = no" and
for NT4 DCs you need "require strong key = no" and "client NTLMv2 auth = no",
On the server side (as domain controller) we have the following new options:
"allow nt4 crypto" (no by default), "reject md5 client" (no by default).
E.g. in order to allow Samba < 3.0.27 or NT4 members to work
you need "allow nt4 crypto = yes"
winbindd does not list group memberships for display purposes
(e.g. getent group <domain\<group>) anymore by default.
The new default is "winbind expand groups = 0" now,
the reason for this is the same as for "winbind enum users = no"
and "winbind enum groups = no". Providing this information is not always
reliably possible, e.g. if there're trusted domains.
Please consult the smb.conf manpage for more details of this new options.
