SUMMARY
***
SMB shares are case insensitive, however Dolphin does not provide correct feedback / handle this elegantly
***


STEPS TO REPRODUCE
1. Create an SMB share if none exists
2. Create a folder and mount SMB share onto the folder
3. Using Dolphin, navigate into the folder
4. Create a file called 'test.txt'
5. Attempt to rename the file to 'Test.txt'

OBSERVED RESULT
A "File Already Exists" dialog pops up, asking the user if they wish to Overwrite an existing file or Cancel; clicking Overwrite will simply prompt the user again as the operation fails

EXPECTED RESULT
Either a successful rename or an "Operation failed" message

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.24.5
KDE Frameworks Version: 5.90.000
Qt Version: 5.15.2

ADDITIONAL INFORMATION
FAT32 file systems, despite also being case-insensitive, do not have this issue.
