samba - Feb 2005 - Error while opening a Excel VBA file in a Samba PDC client

Hi All,

Server OS - SuSE Pro 9.0
Samba server version - samba3-3.0.9-1 (SuSE rpm)
Client - Windows XP Pro SP 2
Office XP SP 2

I have everything working well like machines joining domain, users 
logging in, roaming profiles etc. But when a user of the Samba domain 
tries to open a Excel VBA document, the following error occurs.
"Error accessing the system registry"

Please note that the macro security settings are at LOW. If I say OK to 
the previous error, then the system opens a window titled "Identity 
Login" with 2 buttons "Log Off Identity" and "Manage
Identities" and 2
other buttons "OK" and "Cancel". No actual identities are
shown in this
window. And because of this reason "OK" button is greyed out. If I hit
"Cancel", then the system opens up the Excel sheet, but with an error 
window saying essentially,

#############################################################
Microsoft Excel File Repair Log

Errors were detected in file 'C:\Documents and 
Settings\prakash\Desktop\autox4.xls'
The following is a list of repairs:

Lost Visual Basic project.
Lost ActiveX controls.

I googled around, and tried this article from Microsoft KB, 
"http://support.microsoft.com/kb/q269383/", but to no avail.

I turned on debugging on the server to 10, but does not help. I can see 
that the server complains about some DLL files being unavailable, but 
these errors don't show up when I try to open the excel sheet.

I am attaching the smb.conf file along; Please help.

Thanks,
Prakash
