Does it make a difference if you re-mount the volume without 'acl'
option? Even otherwise can you try listing the snapshot contents from
the server as a user(and not super user) who in reality tries to list
previous versions from Windows? I feel like it has something to do with
permissions setup for the user accessing the share.
