Hai,
If i may suggest..
AD-DC, fine no changes needed.
File server smb.conf, i made some changes, see below.
I change the keytab and kerberos methode because your thinking that related to the problem.
And i changed some settings below, which are moved from Global setting to Share setting.
3 settings where defined as (S) as in, its a "share" setting, so put it in the share definition.
Now i suggest, play with these 2:
access based share enum = yes
smb encrypt = desired
Other option try : acl_xattr:ignore system acls = yes
In place of acl_xattr:default acl style = windows
Try as shown with the config below, then turn the smb encrypt off, try again.
Then the other, try again. You know the drill. ;-) test the 3 changes share settings.
Stop and start samba after changing these settings ( no restart ).
Just to make sure everything is loaded as it should.
(the file server's ) adjusted smb.conf
[global]
dedicated keytab file = /etc/krb5.keytab
kerberos method = secrets and keytab
workgroup = REALM
security = ads
realm = REALM.EXAMPLE.COM
# Logging
log file = /var/log/samba/%m.log
log level = 3
idmap config REALM : range = 2000000-2999999
idmap config REALM : backend = rid
idmap config * : range = 10000-999999
idmap config * : backend = tdb
winbind use default domain = no
winbind refresh tickets = yes
winbind offline logon = yes
winbind enum groups = no
winbind enum users = no
username map = /etc/samba/user.map
bind interfaces only = yes
interfaces = lo eth0
vfs objects = acl_xattr
map acl inherit = yes
store dos attributes = yes
#disable netbios = yes
# just disable the start up of nmbd.
template shell = /bin/false
template homedir = /srv/samba/Users/%U
[Users]
acl_xattr:default acl style = windows
access based share enum = yes
smb encrypt = desired
path = /srv/samba/Users
comment = Share for user home dirs
guest ok = no
read only = no
[Shared]
acl_xattr:default acl style = windows
access based share enum = yes
smb encrypt = desired
path = /srv/samba/Shared
guest ok = no
read only = no
