[Samba] samba4 on debian squeeze

[L.P.H. van Belle]

hai, 
 
Im trying to install samba4 on my debian squeeze server. 
 
all needed files are from debian unstable. 
 
When i install samba4  ( apt-get install -t unstable samba4 ) which is beta1 is in debian unstable. 
at the end im getting the following error.. 
 
get_nt_acl_no_snum: fset_nt_acl returned zero.
ProvisioningError: Your filesystem or build does not support posix ACLs, s3fs is unworkable in this mode
dpkg: error processing samba4 (--configure):
 subprocess installed post-installation script returned error exit status 1
