I have built 4.4.3 on CentOS 6, with a fairly minimalist smb.conf,
provisioned the domain as per the wiki [1], and cannot get past test one:

[root@frodo ~]# smbclient -L localhost -U%
Domain=[ADTEST] OS=[Windows 6.1] Server=[Samba 4.4.3]
tree connect failed: NT_STATUS_CONNECTION_DISCONNECTED

I can get output if I specify a username, and give a password, but
anonymous access seems to be blocked.

[root@frodo etc]# smbclient -L localhost -Ugeoff
Enter geoff's password:
Domain=[ADTEST] OS=[Windows 6.1] Server=[Samba 4.4.3]

My smb.conf, such as it is (I have redacted the domain name):

[root@frodo etc]# cat smb.conf
# Global parameters
[global]
netbios name = FRODO
realm = ADTEST.XXXX.CO.UK
workgroup = ADTEST
dns forwarder = 212.23.3.100
server role = active directory domain controller
idmap_ldb:use rfc2307 = yes
log level = 1
guest ok = yes

[netlogon]
path = /usr/local/samba/var/locks/sysvol/adtest.xxxx.co.uk/scripts
read only = No

[sysvol]
path = /usr/local/samba/var/locks/sysvol
read only = No

[big]
path = /big
read only = No

Am I misunderstanding the wiki? Or is this test unimportant, and I
should just move on? Thanks for any light anyone can shed.

Might be a stupid question, but have you started Samba?

I think that shows it's running, no?

OK, I can confirm this, I was using 4.4.2 and running the same command,
I got this:

root@dc1:~# smbclient -L localhost -U%
Domain=[SAMDOM] OS=[Windows 6.1] Server=[Samba 4.4.2]

A short while later, after I updated to 4.4.3, nothing else changed:

root@dc1:~# smbclient -L localhost -U%
Domain=[SAMDOM] OS=[Windows 6.1] Server=[Samba 4.4.3]
tree connect failed: NT_STATUS_CONNECTION_DISCONNECTED

It seems there is a bug report for a similar problem, see:
https://bugzilla.samba.org/show_bug.cgi?id=11858

The release notes for 4.4.3 seems to suggest this is supposed to be fixed:

Stefan Metzmacher <me...@samba.org>
.......
* BUG 11858: Allow anonymous smb connections.

I, too, can confirm that going back to samba 4.4.2 fixes the problem.
Thank you!
