+> The default setting of **auto** allows clients that support case sensitive filenames (Linux CIFSVFS)
+> 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). No Windows system supports case-sensitive filenames so setting this option to **auto** is the same as
+> setting it to No for them; however, the case of filenames passed by a Windows client will be preserved.  This setting can result
+> in reduced peformance with very large directories because Samba must do a filename search and match on passed names.
+>
+> A setting of **Yes** means that files are created with the case that the client passes, and only accessible using this same case.
+> This will speed very large directory access, but some Windows applications may not function properly with this setting.  For
+> example, if "MyFile" is created but a Windows app attempts to open "MYFILE" (which is permitted in Windows), it will not be found.
+>
+> A value of **Forced lower** is special: the case of all incoming client filenames, not just new filenames, will be set to lower-case.
+> In other words, no matter what mixed case name is created on the Windows side, it will be stored and accessed in all lower-case.  This
+> ensures all Windows apps will properly find any file regardless of case, but case will not be preserved in folder listings.
+> Note this setting should only be configured for new shares.
