Hi, first of all update your samba version , you find suses samba 3 packs on ftp.suse.com projects samba data base errors are well known

Kernel Oplocks are essentially a method that allows the Linux kernel to co-exist with Samba's oplocked files, although this has provided better integration of MS Windows network file locking with the underlying OS, SGI IRIX and Linux are the only two OSs that are oplock-aware at this time.
Unless your system supports kernel oplocks, you should disable oplocks if you are accessing the same files from both UNIX/Linux and SMB clients. Regardless, oplocks should always be disabled if you are sharing a database file (e.g., Microsoft Access) between multiple clients, as any break the first client receives will affect synchronization of the entire file (not just the single record), which will result in a noticeable performance impairment and, more likely, problems accessing the database in the first place. Notably, Microsoft Outlook's personal folders (*.pst) react quite badly to oplocks. If in doubt, disable oplocks and tune your system from that point.

a solution maybe
You can disable oplocks on a per-share basis with the following:
[acctdata]
oplocks = False
level2 oplocks = False
The default oplock type is Level1. Level2 oplocks are enabled on a per-share basis in the smb.conf file.
Alternately, you could disable oplocks on a per-file basis within the share:
veto oplock files = /*.mdb/*.MDB/*.dbf/*.DBF/

Hi All,
scenario: Samba Version 2.2.8a-UL running on Suse Linux Enterprise 8 Kernel Version 2.4.21-241-smp as Server
Windows 2000 SP4 as Client
Trying to import a MS-Foxpro file into MS-ACCESS. MS-Foxpro File residing on Samba Server. The Foxpro filename is 'projects.dbf'. During import MS-Access tries to also open a non existent file 'projects.inf' depending on the path in which the file resides Samba will return different Error Messages to the smb client (windows machine)
either NT_STATUS_OBJECT_NAME_NOT_FOUND which is correct (Example 1)
or NT_STATUS_ACCESS_DENIED which is the wrong return code. (Example 2)
Aur problem was that a filename like 'cad/pipe/projects.dbf' resulted in the access denied message wich led the MS-Access Programm into error whilst a filename like 'test/pipe/projects.dbf' will return with the correct file not found.
Any 3 letter or less path before the /pipe/ results in the error. We've managed to level it down to the "Check a filename for the pipe string." Function static void check_for_pipe(const char *fname) in the Samba source code 'open.c'.
Our solution for now is not to name any directory 'pipe' so that the parsing function won't get confused but this can't really be a solution.
Any Ideas welcome.
Best regards
