Description jason qian (e-mail address couldn't be found) 2006-01-30 16:55:35 UTC
Here is the problem:
1. Our Quickbooks Enterprise version support 5 users to access the database files which can be located in a network share.
2. Then setup the network share in a Linux 2.4.20 and Samba 3.0.21a PC
3. When 5 users try to access Quickbooks data files at the same time, only 1 or 2 users can access, others just get rejected.
4. Then change the smb.conf oplocks to 0, now 5 users can access at the same no problem.

This seems a problem in Samba 3.0.21a.

Please try 3.0.21b when released. There was a bug fixed in just this area.
Jeremy.

We test 3.0.21b with Quickbooks multiple user mode, it still failed to allow more than 1 user to open the Quickbooks files shared by Samba 3.0.21b.

Forget to say, this problem is gone only after turn off OPLOCKS.
Comment 4 Jeremy Allison 2006-02-06 17:18:25 UTC
Please send a debug level 10 log and an ethereal trace of this happening.
Thanks.
Jeremy.

IIRC Intuit recommends disabling oplocks even on Windows servers.
Can you confirm that this works on a vanilla install of a 
Windows server?
