Hi,
I cannot get Windows 10 to connect to my Samba server without SMB1.
I get the following error when I try to join Windows 10 client to Samba
4.11.13 AD. I get the following error on the client:
"The following error occurred attempting to join the domain
'local.richardshapiro.com':
You can't connect to the file share because it's not secure. This share
requires the obsolete SMB1 protocol, which is unsafe and could expose
your system to attack. Your system requires SMB2 or higher. For more
info on resolving this issue, see
https://go.microsoft.com/fwlink/?linkid=852747"
I get the following on the server:
"Feb 27 20:43:06 ss-prod smbd[7323]: [2021/02/27 20:43:06.043958, 0,
pid=7323, effective(0, 0), real(0, 0)]
../../source3/smbd/negprot.c:593(reply_negprot)
Feb 27 20:43:06 ss-prod smbd[7323]: negprot got no protocols"
If I enable SMB1 on the Windows 10 client it can join the domain just
fine. Without SMB1, it fails every time. I have tried numerous Samba
configuration options on the Samba server, but none work.
Server info:
CentOS Linux release 7.9.2009
[root at ss-prod packages]# uname -a
Linux ss-prod.rsa.richardshapiro.com 3.10.0-1160.15.2.el7.x86_64 #1 SMP
Wed Feb 3 15:06:38 UTC 2021 x86_64 x86_64 x86_64 GNU/Linu
Samba 4.11.13 built from source
I have tried numerous options on the server:
server max protocol = SMB2
#min protocol = SMB2
# min protocol = SMB2
# server min protocol = NT1
#server min protocol = SMB2_10
#server max protocol = SMB3
#protocol = SMB
Shouldn't 4.11.13 support SMB2 or higher?
