[Samba] getcifsacl does not work with CIFS mount versions 2 or 3

[Miloslav Hůla]

Hi

When I mount CIFS share (mount -t cids) with vers=1.0 I can perform 
getcifsacl sucessfully. But when I mount with vers=2.0, or 2.1, or 3.0, 
ACL reading fails.

getxattr error: 95
REVISION:0x0
CONTROL:0x0

Why getcifsacl depends on SMB protocol version? Can I read ACL via newer 
SMB protocol?

A asked on Serverfault but without reply:

Thank you,
