[Samba] Problems Samba+Excel File

[Jubacca]

Hi , I'm New on this list.

I have some problems with samba 3.0.14a Ldap Backend Ubuntu version.

I have some excel file inside a share. When I open a file with connections
to other files , the system is very slow.

I check on mailing List and I have found this option:

 

lock directory = /usr/local/samba/var/locks 

share modes = yes 

oplocks = true 

locking = yes

 

and 

 

veto oplocks .ecc. Ecc.= .xsl 

 

But this don't solve my problem.

Now , Someone can help me ?

Tank you very much.

Bye Jube
