Re: [Samba] Can't set SeDiskOperatorPrivilege to Domain Admins. (NT_STATUS_NO_SUCH_USER) Error.




Thanks for everyone chiming in on my problem. I really do appreciate it.

Just to clarify, I’m working on a share called Edwards_Public. I’m trying
to get it so the members of the AD group called do_superintendent are the
only people able to read and write any files in that directory.

Here is my global config:

workgroup = NSD
client signing = yes
client use spnego = yes
kerberos method = secrets and keytab
log file = /var/log/samba/%m.log
log level = 5
realm = NSD.NEWBERG.K12.OR.US
security = ads
wide links = yes
unix extensions = no
obey pam restrictions = yes
hide files = /$*/
hide files = /*.tmp
hide special files = yes
hide dot files = yes
veto files = /.DS_Store/
delete veto files = yes

Based on the recommendations in this thread I’ve done the following:

setfacl -m g:"domain admins":rwx,g:"domain users":rx Edwards_Public

net rpc rights grant "BUILTIN\Administrators" SeDiskOperatorPrivilege -U
"NSD\Administrator"

Still not having any luck though.

Jurie:
>>Why not set your permissions from the windows server via security tab on
folder properties?
I would like to do that. My account (mcparlandj) is in the domain admin AD
group. But when I use the “Computer Management” application on Windows 7,
click properties for the share I want to edit the permissions on and click
the Security tab, I see this:

“You do not have permission to view or edit this object’s permission
settings”

If I click on the Share Permissions tab, I’m able to add / remove / modify
permissions for “Groups or user names”, but they don’t seem to actually
work or do anything. For example, I set the do_superintendent group to
allow Full Control, Change, Read. When I login to a windows machine as a
user that is a member of the do_superintendent group and I click on the
share they should have access to, I get a log and password prompt that pops
up. I’m not able to get into that share.

Also, another weird thing is after awhile I’ll go back to the “Computer
Management” application, click on the Share Permissions tab, all the group
names have changed into what look like SID numbers and the little person
icon has a red question mark next to it.

Lastly, I’ve opened an SSH session to the server, changed into the share in
question. Then did an su to the user in the do_superintendent group and
tried to create a file. I wasn’t able to. This may be expected behavior
though as an ssh session doesn’t use SMB, but I’m grasping at straws trying
to figure out what’s wrong.
