The problem was very simple. In the parent folder where I had the
Samba shares there were no permissions to execute. They could not
access the folder.
The strange thing is that under certain conditions they could access
it. By adding read and execute to the parent folder where the samba
shared started to work.
It is fixed. I still found the behavior a little strange.
Regards.
