Probably your Samba or kernel version is too old.  This has nothing to
do with ACLs.  Either Samba isn't monitoring files for changes (upgrade
Samba) or the required facility isn't available (kernel too old.)  I
think the code has been in the kernel for a long time, so probably a
Samba upgrade is in order.

FWIW I used to have this issue on Samba 3.0.x but not any more on 3.2.x.



The samba 3.0.x series displays new files fine, it has to do with kernel conflicts.

For example, on one of our RHEL5.3 servers we are using the kernel 2.6.18-92.1.13.el5xen and Samba Version 3.0.31-SerNet-RedHat, and leaving inotify enabled causes runaway smb processes and spams log files that fill terabyte arrays.  In order to stop this we had to specify
        kernel change notify = no
in smb.conf, but newer kernel versions don't have this problem.  As far as I am aware, this is also only an issue when files are created via a non-smb process (i.e. sftp, local cp, etc.)

Newer kernel versions (i.e. 2.6.18-164.el5) work fine with Samba Version 3.0.33-3.14.el5, and if you create files locally they show up almost immediately on the client.
