 Dear Rowland Penny
 I follow your mentioned step still i am face the same problem
I have 1 Domain Controller [sambadc] and 1 Domain member for Samba Share and backup [backupserver]

1.when try view the ACL rights is backup server i can able view the domain user name
[root at backupserver Rishinox]# getfacl /ADHDD/Rishinox/
getfacl: Removing leading '/' from absolute path names
# file: ADHDD/Rishinox/
# owner: administrator
# group: domain\040users
user::rwx
user:administrator:rwx          #effective:r-x
group::rwx                      #effective:r-x
group:domain\040users:r-x
group:domain\040admins:rwx      #effective:r-x
mask::r-x
other::r-x
default:user::rwx
default:user:administrator:rwx
default:group::rwx
default:group:domain\040users:r-x
default:group:domain\040admins:rwx
default:mask::rwx
default:other::r-x

2. My smb.conf file in backup server

[root at backupserver Rishinox]# vi /etc/samba/smb.conf

[global]
#--authconfig--start-line--
# Generated by authconfig on 2017/10/27 10:57:19
# DO NOT EDIT THIS SECTION (delimited by --start-line--/--end-line--)
# Any modification may be deleted or altered by authconfig in future

   workgroup = RISHI
   password server = sambadc.rishi.com
   realm = RISHI.COM
   security = ads
   idmap config * : range = 16777216-33554431
   template shell = /bin/bash
   kerberos method = secrets only
   winbind use default domain = yes
   winbind offline logon = true

  vfs objects = acl_xattr
   map acl inherit = yes
   store dos attributes = yes

#--authconfig--end-line--
;       workgroup = SAMBA
;       security = user

        passdb backend = tdbsam

        printing = cups
        printcap name = cups
        load printers = yes
       cups options = raw

[Rishinox]                                   ---> This my Samba Share                           
   path = /ADHDD/Rishinox
   read only = no
   inherit acls = yes
   browseable = yes
   valid users = +rishi\"Domain Users"
   vfs objects = acl_xattr
   map acl inherit = yes
   store dos attributes = yes

3. I can able to view the Domain user id in backupserver
[root at backupserver Rishinox]# id RISHI\\administrator
uid=16777216(administrator) gid=16777220(domain users) groups=16777220(domain users),16777221(group policy creator owners),16777222(denied rodc password replication group),16777223(enterprise admins),16777224(schema admins),16777225(domain admins),16777217(BUILTIN\users),16777216(BUILTIN\administrators)


4.When try to check the domain user id, set the acl and change the owner of file  i get the following error  in Domain controller

[root at sambadc Rishinox_Share]# chown root:"Domain Admins" /ADD_Drive/Rishinox_Share/COMMON/      
        chown: invalid group: ‘root:Domain Admins’
[root at sambadc Rishinox_Share]# setfacl -m "u:RISHI\Administrator:rwx" /ADD_Drive/Rishinox_Share/
setfacl: Option -m: Invalid argument near character 3
[root at sambadc Rishinox_Share]# id RISHI\\administrator
id: RISHI\administrator: no such user
5.When try the view the ACL rights i get following message not shown the Domain user name, it shows the user id ?

[root at sambadc Rishinox_Share]# getfacl /ADD_Drive/Rishinox_Share/
getfacl: Removing leading '/' from absolute path names
# file: ADD_Drive/Rishinox_Share/
# owner: 16777216
# group: 16777220
user::rwx
user:root:rwx                   #effective:r-x
group::---
group:root:---
group:users:r-x
group:3000000:rwx               #effective:r-x
mask::r-x
other::r-x
default:user::rwx
default:user:root:rwx
default:user:3000000:rwx
default:group::r-x
default:group:root:r-x
default:group:users:r-x
default:group:3000000:rwx
default:mask::rwx
default:other::---
6.  MY smb.conf file for Domain Controller

[root at sambadc Rishinox_Share]# cat /usr/local/samba/etc/smb.conf
# Global parameters
[global]
        workgroup = RISHI
        realm = RISHI.COM
        netbios name = SAMBADC
        server role = active directory domain controller
        server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbind, ntp_signd, kcc, dnsupdate
         idmap_ldb:use rfc2307 = yes

[netlogon]
        path = /usr/local/samba/var/locks/sysvol/rishi.com/scripts
        read only = No

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


[Rishinox]
        path = /ADD_Drive/Rishinox_Share
        read only = no

7. I am already check the Libs file link and ACL setup in Domain Controller

# smbd -b | grep HAVE_LIBACL
   HAVE_LIBACL

[root at sambadc Rishinox_Share]# net rpc rights list privileges  SeDiskOperatorPrivilege -U 
                                "RISHI\administrator"

[root at sambadc Rishinox_Share]# net rpc rights grant "RISHI\Domain Admins" SeDiskOperatorPrivilege -U
                                     "RISHI\administrator"


[root at sambadc Rishinox_Share]# ls -ll /lib64
lrwxrwxrwx. 1 root root 9 Oct 26  2017 /lib64 -> usr/lib64

[root at sambadc Rishinox_Share]# ls -ll /lib64/libnss_winbind.so
lrwxrwxrwx 1 root root 26 Nov 28 18:27 /lib64/libnss_winbind.so -> /lib64/libnss_winbind.so.2


I don't know what i am make the wrong thing in configuration


Thanks & RegardsBaranitharan

Samba 4.1.x is EOL, you really should upgrade.

'samba-tool user list' works in the same way as 'wbinfo -u', it goes
direct to AD.
If getent doesn't work, it is usually because the libnss-winbind links
are not set up, see here:

https://wiki.samba.org/index.php/Libnss_winbind_Links

Make the share look like the above and then read this:

https://wiki.samba.org/index.php/Setting_up_a_Share_Using_Windows_ACLs

You must use Windows ACLs on a share on a DC.

It looks like you are using sssd, if so, can I suggest you use winbind
instead, see here:
