I will integrate the wheel group into the HowTo, the integration in the AD would be vy cool…
For running virtualized Windows still are necessaries licenses.
I recently used only Xubuntu as Client Enviroment. Someone had some experience with OpenSUSE or Debian?

Followed your How to On a Fedora from

(although one nasty quirk: authentication of screensaver does not work for me.)
Instead of locally adding admin and administrator to the
wheel group, i make a wheel group on my Nethserver (
email@example.com) and added the domain admins group (
domain firstname.lastname@example.org) to it as members and a regular user (i.e.
On the domain-client (only) the users added to
email@example.com group (ie admin, administrator and john) have sudo rights
Install Suse ( https://de.opensuse.org/Portal:42.3 1 to download ) I use the Gnome version.
After Install search for domain windows in the Dash- there will be an oppertunity to connect to a WIndows Domain- Put in your credentials, then there will be installation of further software, please accept; I think after a restart using at login other User you should be able to log in to your domain using "yourdomain\user

What we also did for having all the data on the server: Mounting the home directory directly at the users home on NS- which is absolutly great- all files and settings are directly stored at the Server and also therefore backuped with the normal backup prozedure- only the network connection must be garanteed. Done on every cllent makes roaming unnecessary. See also Roaming profiles in ns7 Active Directory
We had trouble using our Java based medical documentation software on Gnome so we changed/ additionally installed the KDE Desktop.
Hope that works.
I’m running 4 OpenSuse right now, mostly for test, but one on my laptop;
But you could also make a edgy CentOS by using the last kernel with elrepo;
than making snapshot with snapper by using https://copr.fedorainfracloud.org/coprs/andybe/Centos7Btrfs/packages/
As I mention in another post; the most advantage of OpenSUSE is to be a Rolling Version, than after that snapper.
I also have a VM running Nethserver on btrfs with the last kernel and snapper;
Let’s say; for now everything works fine.
Hi JOduMonT, do you mean the hypervisor or the NS runs on btrfs?
I guess the hypervisor, which one do you use?
The KVM hypervisor is a OpenSUSE Tumbleweed which use brtfs
The VM is based on CentOS/Nethserver which also run on brtfs
oh! in case you ask
simply install CentOS as usual but choose btrfs as filesystem
then initiate snapper
- install the repo
- install the soft + the plugin for yum :
yum install -y snapper yum-plugin-snapper
- create the config for your root
snapper -c root create-config /
enjoy and use at your own risk
Oh, vy nice! I have to investigate this solution…
Tried it but without luck, did you do something else?
[admin@ap002 ~]$ groups domain users domain admins denied rodc password replication group wheel [admin@ap002 ~]$ sudo su [sudo] Passwort für admin: admin ist nicht in der sudoers-Datei. Dieser Vorfall wird gemeldet.
I was able to get sudo rights with the edit of /etc/sudoers:
%domain\ admins ALL=(ALL) NOPASSWD: ALL
But of course this is not the same as the wheel-group method…
No, no extra steps. Did it on fedora, let me spin up a centos vm and report my findings.
OK, thank you, there is no hurry…
Can confirm it does not work on Centos out of the box.
Deducted it to differences centos <> fedora in configuration of nsswitch.
It worked as expected after boldly taking fedora’s nsswitch.conf :
EDIT: removed nsswitch.conf
Did not find smoking gun witch settings made it possible, just adding the missing
sudoers: files to the centos default nsswitch.conf did not do the trick. hence the bold move, which no one should do!, to take the complete configuration over.
EDIT: found “the smoking gun”
OK Mark, thank you for confirming this issue…
Found why the “ad wheel group” works on fedora and not on centos, on centos in /etc/nsswitch.conf:
order of service- calls for
group matters: first call the
sss and second

Very good, I will try it in the next days… Thank you
