please refer to this bug report: https://gitlab.gnome.org/GNOME/gvfs/-/issues/721#note_2046184 The smbclient of gvfs is not working correctly in regards of case sensitivity if the auto argument for the case sensitive option is set. >The default setting of auto allows clients that support case sensitive >filenames (Linux CIFSVFS and smbclient 3.0.5 and above currently) to >tell the Samba server on a per-packet basis that they wish to access >the file system in a case-sensitive manner (to support UNIX case >sensitive semantics)
(In reply to remasch from comment #0) I am sorry, but this isn't (yet) supported by SMBv2 on Linux, it will be when the smb2 Unix extensions are complete.
