Hello,
After upgrading to samba 4.13 (from debian oldstable to debian stable),
some windows clients (windows 2008r2 and lower, Indows 7, windows XP,
etc) can't connect to the serveur anymore. My first move was to enable
SMBv1, now some linux clients connect using the older protocol, but the
windows client still fail to connect "can't connect" error, neither
using the UNC name, nor the IP adress; neither from the windows
explorer, or "net use //xxxx/yyy" in a CMD shell.
Any ideas?
The global part of smb.conf:
[global]
workgroup = EXAMPLE
security = ADS
realm = EXAMPLE.LAN
# allow SMB1
ntlm auth = ntlmv1-permitted
server min protocol=NT1
dedicated keytab file = /etc/krb5.keytab
kerberos method = secrets and keytab
server string = Data %h
winbind use default domain = yes
winbind expand groups = 4
winbind nss info = rfc2307
winbind refresh tickets = Yes
winbind offline logon = yes
winbind normalize names = Yes
## map ids outside of domain to tdb files.
idmap config *:backend = tdb
idmap config *:range = 2000-9999
## map ids from the domain the ranges may not overlap !
idmap config EXAMPLE : backend = rid
idmap config EXAMPLE : range = 10000-999999
template shell = /bin/bash
template homedir = /home/EXAMPLE/%U
domain master = no
local master = no
preferred master = no
os level = 20
map to guest = bad user
host msdfs = no
# user Administrator workaround, without it you are unable to set
privileges username map = /etc/samba/user.map
# For ACL support on domain member
vfs objects = acl_xattr
map acl inherit = Yes
store dos attributes = Yes
# Share Setting Globally
unix extensions = no
reset on zero vc = yes
veto files = /.bash_logout/.bash_profile/.bash_history/.bashrc/
hide unreadable = yes
# disable printing completely
load printers = no
printing = bsd
printcap name = /dev/null
disable spoolss = yes
