[Samba] samba-tool gpo aclcheck error

[L.P.H. van Belle]

Hai, 

Using Ubuntu 12.04.3 x64, sernet samba 4.1.3 

Im having the following errors. 

samba-tool gpo aclcheck

this is a clean install, no gpo set yet, no files in the sysvol. 
I only did set the rights on the share, as the samba wiki says.
