I have an NT domain on Debian Stretch. It's been upgraded numerous
times, but has been running for almost a decade. Since upgrading from
4.1.17 to 4.3.3 (huge Debian jump), then to 4.3.6, clients cannot
connect to shares. Prior to upgrading, I found the changes mentioned
for 4.2 regarding NT domains and applied them. Even so, I still cannot
connect to network shares nor print to network printers.

The winbind error messages are correct, as I use nss_ldap/pam_ldap for
authentication, and that works. getent retrieves all ldap users and
groups on both DC and member. I can successfully ssh into either the DC
or member. Oddly, I can access a share on the DC from the Win7 system,
but no other shares.
Can anyone spot what I've missed in the upgrade?
Thanks,
Dale
No takers thus far. These are the Samba 4.2 changes to which I
previously referred (https://www.samba.org/samba/history/samba-4.2.0.html) :
For the client side we have 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"
I believe I have applied them correctly, but have not had any success to
date. All member servers are Debian Jessie or Stretch, and the Windows
systems are all Win7.
Can anyone please advise as to why the clients see no logon server?
Thanks,
Dale

You may have included this in another email however I will ask anyway, did you set DNS to your server in the Linux and Windows clients? Can you check if a Windows Server can join?
