Glad you got the permissions set, I will update the wiki.
Without that line, you will now have three sets of permissions in play:
A) the standard Linux ugo permissions that 'ls' can show
B) the extended acls that 'getfacl' will show
C) the permissions that you have set from Windows and are stored in an EA
Linux will use A & B, Windows will use C if set and if set (without the
'acl_xattr' line), then the Windows permissions will effect the extended
acls, if not set, then A & B will be ignored. You can find more about
this in 'man vfs_acl_xattr'
