Good morning people,

I make the case that Achim Gottinger passed.

samba-tool ntacl sysvolreset and received the following information:
Segmentation fault (core of the recorded image)

then sent a samba-tool ntacl sysvolcheck and received the following:
ERROR (<type 'exceptions.TypeError'>): uncaught exception - (61 'No data available')
  File "/usr/lib64/python2.7/site-packages/samba/netcmd/__init__.py", line 175, in _run
    self.run return (* args, ** kwargs)
  File "/usr/lib64/python2.7/site-packages/samba/netcmd/ntacl.py", line 249, in run
    lp)
  File "/usr/lib64/python2.7/site-packages/samba/provision/__init__.py", line 1717, in checksysvolacl
    fsacl = getntacl (lp, dir_path, direct_db_access = direct_db_access, service = SYSVOL_SERVICE)
  File "/usr/lib64/python2.7/site-packages/samba/ntacls.py", line 73, in getntacl
    xattr.XATTR_NTACL_NAME)

Will there this the source of my problem? hehehehe

Remembering that I'm using Centos 7 and Samba version 4.1.17-Sernet-RedHat-11.el7

Sincerely,

Gabriel Franca
