[Samba] XP Client cannot join Samba3 PDC

[Jose Martinez]

When u used these FORCE user and group settings, you didn't have to tell it
which user and group to force?

Can you send a copy of your smb.conf file.

The problem I am having is that sometimes a machine that is connected to the
domain will not allow a user to authenticate.. but it allows other users to
authenticate.. Im wondering if this could be related...

Jose

Resolved problem:
Had decided to use global force user/force group options for the shares.  
It worked like a charm.  All my shares now had default groups and users.
I did not realize how truly global these settings were.  After a careful
review of the logs,  I noticed that root indeed logged in.  However, the
effective user always morphed into nobody.  At that time, I thought this was
nominal behavior.  NOT!

The global settings for:
FORCE USER = unix user
FORCE GROUP= unix group
Sets the Effective User ID to those forced ID's for EVERYTHING, including
non share oriented communications.
Check your configs and eliminate these GLOBAL settings.  

30 hours!  DOH!

	I have found the same problem no and again especially if you remove
a
	machine and then want to rejoin I'm assuming that you use root to
for the
	account and that is exists in you samba setup.

	I found that when it happens to me that quickest and easiest way to
resolve
	the issue is to rebuild the machine I found the problem with XP and
2003
	don't know what causes the issue and I think lots of people have the
same
	problem as it is not the first time this has come up on the posts.

	--------
	
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters]
	"RequireSignOrSeal"=dword:00000000 If you still have changes, you

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters]
	"sealsecurechannel"=dword:00000000
	
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters]

	smbpasswd -a -m WORKSTATION_NAME


	
----------------------------------------------------------------------------
	--------
	SYMPTOMS
	
----------------------------------------------------------------------------
	--------
	CAN authenticate from domain members added prior to migration
	CAN use shares from 95/XP/Samba using share based authentication
	username/password
	CAN join domain form another Samba3 box

	CANNOT join domain from XP
	XP client reports: Access is denied
	(logged in on XP as Administrator)
	Samba reports (level 10 logging): _samr_open_domain: ACCESS DENIED 
	Both root and nobody appear to authenticate
	Logs indicate insufficient privilege to continue 

	Looks like it might be something on the client?? There are no
warnings or
	errors in any of the XP logs.

	Symptoms are the same from multiple installs of XP to multiple
installs of
	samba

	I have racked my brain for the last week and have even resorted to
reading
	the manual.
	Thank you for any guidance in advance!
