[Samba] Problem file server with microsoft office temp files

[Gabriel Franca]

Good morning people,

I have a problem on my file server with samba in version 4.15.5 with office
files (excel, word etc..).
When someone saves a file in the domain, an 8-character file with the
extension .tmp appears. The server already has hundreds of TMP files that
are not deleted by themselves.

Before it was with centos 8.1 and I migrated it to Rockylinux 8.6 and with
that the samba was updated and the problem appeared.
I installed and configured Almalinux 9 and the same problem happens.

Do you know if there is any configuration I need to do in my smb.conf to
solve this problem?

I'm putting my smb.conf below to see if I'm using something I shouldn't, or
if I'm missing something.
Thank you very much in advance!
