samba-tool gpo aclcheck --> No such element

This command can't be executed:

[root@server:~]$ samba-tool gpo aclcheck 
ERROR(<type 'exceptions.KeyError'>): uncaught exception - 'No such element'
  File "/usr/lib/python2.7/dist-packages/samba/netcmd/__init__.py", line 176, in _run
    return self.run(*args, **kwargs)
  File "/usr/lib/python2.7/dist-packages/samba/netcmd/gpo.py", line 1150, in run
    ds_sd_ndr = m['nTSecurityDescriptor'][0]

... and with the option -U global-admin I get:


Password for [LINUXMUSTER\global-admin]:

What's wrong there or how to fix it?
