This requires the user to click the 'Refresh' button in Windows Explorer to properly see the folders. The files and folders are hosted on our Ubuntu server and shared with Samba and accessed on the Windows clients through various mapped network drives.

These mounted files and folders are what is giving the users trouble in seeing folders correctly. We have other files hosted locally on the Ubuntu server and shared through Samba, but these are NOT giving us problems when browsing them through Windows Explorer. The only files that are giving us this problem are the mounted files.

Debug level 10 logs are needed at this point to see what
the smbd is seeing when looking at the CIFS mounted files.

That would help !
