[Bug 1593944] Re: case sensitivity issues over SMB2 or above

[Paul Smedley]

Description updated per
https://wiki.ubuntu.com/StableReleaseUpdates#Procedure - I will go post
this bug on #ubuntu-bugs now

** Description changed:

  https://bugzilla.samba.org/show_bug.cgi?id=11438 fixes a bug with case
  sensitivity that affects OS/2 clients.
  
  It would be great to have this fix on Ubuntu server
+ 
+ [IMPACT]: Bug fixes the user experience for users of operating systems
+ that don't support case sensitive file systems - eg dos / windows /
+ OS/2.
+ 
+ [TEST CASE]:
+ Problems exist with listing directories using case insensitive names over SMB2 or above.
+ 
+ I have a folder called 'Desktop' in a share called Public on my Samba
+ server running on Ubuntu.
+ 
+ Using SMB3, trying to list the directory fails if I use the case-
+ insensitive name.
+ 
+ psmedley at XPS13:~$ smbclient //192.168.1.200/Public -mSMB3 -d 10 --username=psmedley -N 2> smbclient.log
+ Anonymous login successful

+ smb: \>

+ 		-1366264008 blocks of size 1024. -1997689408 blocks available
+ smb: \> exit
+ 
+ Using SMB1, running ls with the case-insensitive name works fine.

+                 65535 blocks of size 33553920. 65535 blocks available
+ 
+ This occurs with 'case sensitive' set to auto or no in smb.conf
+ 
+ [Regression Potential]:
+ Low - patch is quite small - has been tested by the Samba release team and included in Samba 4.3.10 and 4.4.4

  [IMPACT]: Bug fixes the user experience for users of operating systems

  [TEST CASE]:
  Problems exist with listing directories using case insensitive names over SMB2 or above.

  I have a folder called 'Desktop' in a share called Public on my Samba
  server running on Ubuntu.

  Using SMB3, trying to list the directory fails if I use the case-
  insensitive name.
