Sudden change to Samba login

[Boblitz John <John.Boblitz@BERTSCHI.com>]

Good Morning,
 
I set up several Samba shares several months ago and these were working as expected until recently.  Then I started notincing that the users dod not have the access they should have had based on owner / group priveledges.
 
A day or so ago I created a directory via the shared interface (i.e. not on the server directly!) and noticed that, instead of my username the owner was DOMAIN\username.
 
I dug into the log files and noticed that, up until the 24th of June, the log contained entries such as:
 
[2011/06/24 07:30:42.960995,  1] smbd/service.c:1070(make_connection_snum)
  __ffff_172.28.164.129 (::ffff:172.28.164.129) connect to service tools initially as user USERNAME (uid=0, gid=110) (pid 1684)

On the 27th it suddenly became:

[2011/06/27 07:27:16.942121,  1] smbd/service.c:1070(make_connection_snum)
  __ffff_172.28.164.129 (::ffff:172.28.164.129) connect to service tools initially as user DOMAIN\USERNAME (uid=10004, gid=10004) (pid 17600)


The Windows Network types assure me that nothing had changed on thier side.

I did notice that I had a message concerning a change in Samba and have subsequently added the "map untrusted to domain = yes" to my smb.conf and restarted both samba and my client (to force a new login), but the result is the same.

Here my smb.conf:

[global]
	realm = DOMAIN.DOMAIN
	workgroup = WORKGROUP
	server string = %h Debian Development Server
	interfaces = 172.20.32.27/24, lo
	security = ADS
	auth methods = guest, sam, winbind
	obey pam restrictions = Yes
	password server = dueads03 dueads04 dueads05
	passdb backend = smbpasswd
	pam password change = Yes
	passwd program = /usr/bin/passwd %u
	passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
	unix password sync = Yes
	syslog = 0
	log file = /var/log/samba/log.%m
	log level = 3
	max log size = 1000
	name resolve order = lmhosts host wins bcast
	printcap name = cups
	panic action = /usr/share/samba/panic-action %d
	idmap uid = 10000-20000
	idmap gid = 10000-20000
	username map = /etc/samba/smbusers
	winbind enum users = yes
	winbind enum groups = yes
	winbind use default domain = yes
	map untrusted to domain = yes
	template shell = /bin/bash
	template homedir = /home/%U

[homes]
	comment = Home Folder
	valid users = %S
	read only = No
	create mask = 0750
	browseable = No
	volume = %U Home

[netlogon]
	comment = Domain Logon Service
	path = /home/samba/netlogon
	valid users = %U
	admin users = john
	write list = @admins
	read only = No
	guest ok = Yes
	browseable = No
	locking = No

[profiles]
	comment = Users profiles
	path = /home/samba/profiles
	create mask = 0600
	directory mask = 0700
	browseable = No

[printers]
	comment = All Printers
	path = /var/spool/samba
	create mask = 0700
	printable = Yes
	browseable = No

[print$]
	comment = Printer Drivers
	path = /var/lib/samba/printers

[opt]
	comment = Application Files
	path = /opt
	admin users = john
	read only = No
	create mask = 0775

[projects]
	comment = Application Files
	path = /proj
	admin users = john
	read only = No
	create mask = 0775

[tools]
	comment = Application Development Tools
	path = /data/tools
	admin users = john
	read only = No
	create mask = 0775


I have searched, but I not able to find anything the seems relevant to my problem.

Any ideas? 

Thnaks in advance ...

 

John
