what? One works, the other not ... I interpret that the kernel doesn't 
support the ACL-feature of ext4

wbinfo -g

shows "dom�nen-admins"

while


# wbinfo -g | grep -i admin
specops endpoint protection report admins
dnsadmins
schema-admins
organisations-admins
Binary file (standard input) matches

?? no "domänen-admins" in here

and

net rpc rights grant "DOM\domänen-admins" SeDiskOperatorPrivilege -U 
"DOM\administrator"

fails because the group is not found

I asked that already some times ago

and I try to work around that by granting that right to a group called 
IT and the few admins in there

At 2:30pm we plan to reboot into the other kernel.
