[Bug 1389919] [NEW] Anonymous authentication does not work with mount.cifs

 

Public bug reported:

I have an anonymous-access share on a Windows 2012 server that I'm
trying to mount from Ubuntu 14.04. I can access the share via smbclient
as expected:

$ smbclient -N //foo.example.com/MyShare
Anonymous login successful
Domain=[LAB9320] OS=[Windows Server 2012 Standard 9200] Server=[Windows Server 2012 Standard 6.2]
smb: \> ls
  .                                   D        0  Wed Nov  5 11:46:22 2014
  ..                                  D        0  Wed Nov  5 11:46:22 2014
  test                                D        0  Wed Nov  5 01:58:42 2014

                51111 blocks of size 4194304. 41916 blocks available

However, I can't get the share to mount at all via mount.cifs:

$ sudo mount.cifs //foo.example.com/MyShare /mnt/test -o file_mode=0777,dir_mode=0777,uid=500,gid=124,noperm,guest,sec=none                                                                        
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

For reference, I've modified the following settings in secpol.msc >
Security Settings > Local Policies > Security Options on the Windows
server to enable anonymous access to the share:

1. Network access: Do not allow anonymous enumeration of SAM accounts and shares: Disabled
2. Network access: Let everyone permissions apply to anonymous users: Enabled
3. Network access: Restrict anonymous access to Named Pipes and shares: Disabled
4. Network access: Shares that can be accessed anonymously: MyShare

In addition, I've given the following local SIDs "Full Control" of the
share and the folder itself: Everyone, Guest, and ANONYMOUS LOGON.
Please note that the Guest account is NOT enabled on this system, for
security purposes (I don't want guest auth, I want anonymous auth).
