[Samba] GPO created via samba-tool don't Copy or Backup in RSAT (invalid directory)

  After doing a 'tree' in both directories I've noticed that I made a 
mistake and that restore command should be :
samba-tool gpo restore newtest 
/tmp/tmppofvkose/policy/\{F9003837-A727-443D-A2CE-AE0DBCCBC8A8\}/ -U 
admin --password=a

  instead of :
samba-tool gpo restore newtest /tmp/tmppofvkose/ -U admin --password=a

This way GPO parameters are copied as well. First I did it like that, 
and I may have made too much tests the last days and at one time I began 
to use the wrong /tmp path. So my apologies for this useless noise.

BUT this doesn't fix my first problem : I still cannot Copy/Paste or 
Backup "newtest" GPO in RSAT, while Copy/Paste of "test" GPO works fine :

- "test" GPO is made in RSAT.

- "newtest" GPO is made like this :

samba-tool gpo listall
samba-tool gpo backup {F9003837-A727-443D-A2CE-AE0DBCCBC8A8} # ID of 
"test" GPO I got with "listall"
samba-tool gpo restore newtest 
/tmp/tmppofvkose/policy/\{F9003837-A727-443D-A2CE-AE0DBCCBC8A8\}/ -U 
admin --password=a #super strong password
