Samba does not allow a windows box to rename a file from upper case to lower case. I am running 4.5.8 on a Debian base, and somewhere after 4.1.17 it appears something has changed that is disallowing case change. The freenode #samba channel suggested that it might be a regression, and directed me to file a bug.
This particular machine is not one that I am permitted to direct compile on. I have apt access however and have updated to the latest in the stable Debian repos.
My testing has been limited to ensuring I am using the same smb.conf file that worked under 4.1.17.
Hi! I've verified that this is solved in current 4.6.7.
Changing the case of the filename is working fine with smbclient and Windows 7 and Samba does also send change notifications to other clients about this change.
Can you confirm that?

While I am unable to test with this customer's installation, I was able to confirm correct behavior with the release you indicated on a separate vm.
