I'm trying GPO with samba4.
I execute "samba -i -M single". The version is 4.0.0alpha6-GIT-0e723d8.
In our environment, I can use gpupdate and dsa.msc on XP SP2. When I try to edit 
group policy (by gpmc.msc), the warning message "The Permissions for This GPO 
in the SYSVOL Folder Are Inconsistent with Those in Active Directory" appears, 
but I can edit GPO. And I find the same error as one in your log file 
> Kerberos: TGS-REQ srv1$@CE.SAIGONTECH.INFO.VN from for 
> cifs/ce.saigontech.info.vn at CE.SAIGONTECH.INFO.VN [canonicalize, 
> renewable, forwardable] 

When I saw an error "The network path was not found", I checked access to
\\<domain_name>\sysvol\<domain_name>\ and made it possible, then the error always disappeared. As Mr. Wes Deviers said, if you can access
\\<dc_name>\sysvol\<domain_name>\, this error can occur.
In my experience, the access to \\<dc_name>\sysvol was possible but one to \\<domain_name>\sysvol was not, when I enabled DFS in smbd.conf. 
If you can access to \\<domain_name>\sysvol\<domain_name>\  but have 
"The network path was not found" error, I have no idea.

But VistaSP1 doesn't work well with samba4. I can edit the GPO but the 
group policy on Windows can not be updated.  It was possible on Vista without SP.  I'm checking the VistaSP1 behavior now.
Are there some body have experience in working with Samba4 GPOs with VistaSP1?

Hi all,
    After reading samba log file and network capture file, I think that 
this error is related with KRB5.

    * Log file: Kerberos: Failed building TGS-REP to
    * Capture file: KRB Error: KRB5KDC_ERR_S_PRINCIPAL_UNKNOW (packet
      number 46)

Please find in the attachments for these two files.
