Thank you for your reply. I don't have Cygwin installed on the Windows server. I only have Services for NFS. As for the rsync command, I don't want to preserve the permission at the source as it will overwrite the Windows destination permission.

Windows server 2008 Standard
  • On the domain
  • Has Services for NFS and acts as NFS server
  • NFS share on E drive (allow anonymous access unchecked). Permission have a list of IPs Read/Write ANSI encoding and Root Access Allowed)
  • Identity mapping points to our domain
Linux1
  • Acts as the NFS client
  • Mounts the Windows share
Linux2
  • Rsync data to Linux1 NFS mount causing ownership changes to a domain user account and wipes previous permissions to new ones on files and folders in Windows.
  • Each day, our fix is to change the ownership back to the Administrators group and go to the parent folder and inherit permissions to what was changed from the parent folder on Windows.
It is quite cumbersome to make the ownership changes and manually do the permission changes each day in order for clients to make changes to the Windows files.

I need to find a solution for rsync to make changes to the data while keeping the ownership (Administrators group) and permissions intact.

I'm not too sure how the mapping works but the domain is specified. I'm guessing the user used by Linux to mount and rsync points to a specific domain user. How it chooses the user in the domain I'm not sure. I've noticed that the Linux user (test) points to domain account which contains test (test DOMAIN\1_2_test). Perhaps Linux user maps to same name user in the domain(or has that same name in the userID). But that domain user seem to overwrite the ownership of the file and adds Full Control in the permission which I want to avoid.

I'm not supporting the 2 Linux boxes but I can find out if you need more information at that level.

Hope I've cleared it up a bit more.

NAME
wbinfo - Query information from winbind daemon SYNOPSIS
wbinfo [ -u ] [ -g ] [ -h name ] [ -i ip ] [ -n name ] [ -s sid ] [ -U uid ] [ -G gid ] [ -S sid ] [ -Y sid ] [ -t ] [ -m ] [ -r user ] [ -a user%password ] [ -A user%password ] DESCRIPTION
This tool is part of the Samba suite. The wbinfo program queries and returns information created and used by the winbindd(8) daemon. The winbindd(8) daemon must be configured and running for the wbinfo program to be able to return information. OPTIONS
-u This option will list all users available in the Windows NT domain for which the winbindd(8) daemon is operating in. Users in all trusted domains will also be listed. Note that this operation does not assign user ids to any users that have not already been seen by winbindd(8). -g This option will list all groups available in the Windows NT domain for which the winbindd(8) daemon is operating in. Groups in all trusted domains will also be listed. Note that this operation does not assign group ids to any groups that have not already been seen by winbindd(8). -h name The -h option queries winbindd(8) to query the WINS server for the IP address associated with the NetBIOS name specified by the name parameter. -i ip The -i option queries winbindd(8) to send a node status request to get the NetBIOS name associated with the IP address specified by the ip parameter. -n name The -n option queries winbindd(8) for the SID associated with the name specified. Domain names can be specified before the user name by using the winbind separator character. For example CWDOM1/Administrator refers to the Administrator user in the domain CWDOM1. If no domain is specified then the domain used is the one specified in the smb.conf workgroup parameter. -s sid Use -s to resolve a SID to a name. This is the inverse of the -n option above. SIDs must be specified as ASCII strings in the tradi- tional Microsoft format. For example, S-1-5-21-1455342024-3071081365-2475485837-500. -U uid Try to convert a UNIX user id to a Windows NT SID. If the uid specified does not refer to one within the winbind uid range then the operation will fail. -G gid Try to convert a UNIX group id to a Windows NT SID. If the gid specified does not refer to one within the winbind gid range then the operation will fail. -S sid Convert a SID to a UNIX user id. If the SID does not correspond to a UNIX user mapped by winbindd(8) then the operation will fail. -Y sid Convert a SID to a UNIX group id. If the SID does not correspond to a UNIX group mapped by winbindd(8) then the operation will fail. -t Verify that the workstation trust account created when the Samba server is added to the Windows NT domain is working. -m Produce a list of domains trusted by the Windows NT server winbindd(8) contacts when resolving names. This list does not include the Windows NT domain the server is a Primary Domain Controller for. -r username Try to obtain the list of UNIX group ids to which the user belongs. This only works for users defined on a Domain Controller. -a username%password Attempt to authenticate a user via winbindd. This checks both authenticaion methods and reports its results. -A username%password Store username and password used by winbindd during session setup to a domain controller. This enables winbindd to operate in a Win- dows 2000 domain with Restrict Anonymous turned on (a.k.a. Permissions compatiable with Windows 2000 servers only). EXIT STATUS
The wbinfo program returns 0 if the operation succeeded, or 1 if the operation failed. If the winbindd(8) daemon is not working wbinfo will always return failure. VERSION
This man page is correct for version 2.2 of the Samba suite. SEE ALSO
winbindd(8) AUTHOR
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed. wbinfo and winbindd were written by Tim Potter. The conversion to DocBook for Samba 2.2 was done by Gerald Carter 19 November 2002 WBINFO(1)
