dmesg log


Fedora 16 x84-64, kernel 3.4.7, CIFS 1.78
Ubuntu x84-64, kernel 2.6.31, CIFS 1.60 + patches enabling NTLMv2 

Windows 2003 R2 SBS 64-bit,  Windows 2003 R2 64-bits, Windows 2008 R2 64 bits, Windows XP SP3 32-bit, Win7 + SP1 32-bit

In case of mounting shares from Windows 2003/2008 R2 Server with enabled encryption and mass file coping is started coping process receives errors like: "Permission denied".

Of course, all permissions are ok for files and directories. 

dmesg log looks like in attachment.

For standalone Windows servers this problem is not present.

Workaround - disabling encryption on Windows is not describable 

CIFS 1.60  without NTMLv2 patches works correctly in any cases.
