Hi Samba Users,
I'm in the process of building a Samba4 CTDB /GPFS Cluster joined as a
member server to AD that also supports ACL's .
It has taken some time but almost everything is working now :) . My one
outstanding issue is editing files using Excel 2007 on Windows 7 results in
a 'Document not saved' error. I believe this is an issue with the SMB2
protocol as I can edit the same files with the same user and version of
Excel on a Windows XP workstation. Using Wireshark i can see that
communication between the Windows 7 client is using SMB2 . Excel is quite a
strange beast, it creates temporary files etc..
As a test i have set the parameter "client max protocol = NT1" in the
smb.conf of my cluster members but the Win 7 clients continue to use the
Looking more closely at the communication between the Win 7 client and the
Samba Servers when i attempt a file save in Excel i see that the Client
issues a FILE_INFO/SMB2_FILE_RENAME_INFO request and the samba server
returns a STATUS_ACCESS_DENIED response.
I suspect disabling ACL's would resolve the issue but unfortunately these
are necessary for the project . Ideally i would be able to use SMB2 but it
is not a show stopper if i could force Win 7 clients to use SMB1.
I'm currently using samba 4.0.9 / CTDB 2.4 on Centos 6.4 with GPFS 3.4.0-14.
my smb.conf is pasted below.
Thanks in advance for any comment of feedback.
