samba - Feb 2004 - File sharing violation problem

Hi all!

I have setup samba server (samba 2.2.3a from debian woody distro) as replacement
of NT4 Server box. Samba using NT domain (NT4 Server PDC) to validate passwords.
Everything works perferctly except on little problem. When client (not root
user) opens file that already opened by someone else "File sharing
violation" error appears. Only root (domain administrator user on PDC also
has name "root") can simultaneously open files with anyone else
without any problems.

I think this is not a problem of client application accessing files because with
NT4 they all could work simultaneously.

Please tell me how fix it.

Thanks.

Nikolay
