[SOLVED] Joining Linux Mint 21.1 to Windows Server 2019 Domain

des_a · 03-18-2023, 03:24 PM

When I slowed it down, and then began looking deeper, I found that the problem now, is winbind won't start. I'm peeling through some older threads, yes the process has appearently changed slightly, since older versions, and I came up with this, and I think that it's maybe just in the wrong order. I told you I DID know a little about smb.conf, as it now shows that with THAT file, I'm NOT a total beginner - just with these features.

Code:

#! /bin/sh


echo Install packages needed...
apt install samba-common samba winbind libnss-winbind libpam-winbind krb5-user adcli packagekit
sleep 11
echo

echo Set hostname...
sudo hostnamectl set-hostname main-des-linux.smiley000.local
sudo cp -f /etc/hostname /etc/hostname.old
sudo cp -f /usr/bin/hostname /etc
sudo hostnamectl status
sleep 11
echo

echo Fix resolv.conf...
sudo systemctl disable systemd-resolved
sudo systemctl stop systemd-resolved
sudo systemctl status systemd-resolved
sleep 11
echo


echo Copy configuration files...
sudo cp -f /etc/hosts /etc/hosts.old
sudo cp -f /usr/bin/hosts /etc

sudo cp -f /run/systemd/resolve/stub-resolv.conf /run/systemd/resolve/stub-resolv.conf.old
sudo cp -f /usr/bin/stub-resolv.conf /run/systemd/resolve

sudo cp -f /etc/krb5.conf /etc/krb5.old
sudo cp -f /usr/bin/krb5.conf /etc

sudo cp -f /etc/samba/smb.conf /etc/samba/smb.conf.old
sudo cp -f /usr/bin/smb.conf /etc/samba

sudo cp -f /usr/bin/user.map /etc/samba

sudo cp -f /etc/nsswitch.conf /etc/nsswitch.conf.old
sudo cp -f /usr/bin/nsswitch.conf /etc

sleep 11
echo


echo Test smb.conf
testparm
sleep 11
echo


echo Fix pam configuration...
sudo pam-auth-update
sleep 11
echo


echo Restart samba...
sudo systemctl restart smbd nmbd winbind
sleep 11
echo


echo Join domain smiley000.local...
#sudo net join ads smiley000.local -U Administrator
echo


echo Test Administrator user in AD...
#kinit Administrator
#klist
#kdestroy

echo
#id Administrator@smiley000.local
echo


echo Rebooting in 1 minute...
#shutdown -r +1 "Rebooting for AD logon domain join."
echo


echo
echo

This troubleshooting is actually pretty fun, though I want it to work in the end. It's fun because now, I'm getting somewhere...

The only part that does NOT work, now is, "domain-admins", which goes in /etc/sudoers.d. Now, unless a file is changed, or everything is changed significantly, once again, I will no longer post any file that's not changed. That way, the solution looks better, but here's your WARNING about it.

It appears that everything is working, except for sudoers, and it makes more sense to do something that effects the system in this way, rather than nothing. I think I might have the exact same file as on my other machine, so now I don't know what's wrong. I tried logging off, and on, and I think I might have rebooted once, to no avail.

I will change the domain name, eventually, at least it's my goal now...

des_a · 03-19-2023, 07:19 PM

I built this sudo file, from a tutorial, https://help.ubuntu.com/community/ADAuthentication...

domain-admins:

Code:

%BUILTIN\\administrators                 ALL=(ALL)   ALL
"%SMILEY000\\domain admins"              ALL=(ALL)   ALL

...and that made it work! So from a normal point, the problem is fixed and everything works. However, being the glutton for punishment I feel like for this problem, what, besides syntax, is truely wrong with the "domain admins@domain" group? The syntax is great, but no matter the syntax, it won't understand this group! I heard a lot of things, but with the ssd way, it clearly works, as is, at least on an upgrade of an old version of linux mint, where I'd joined the domain. This way seems supperior, but... How can I create more groups, or fix this one, and make it work in my sudoers file?

I know I just achieved "1.0 status", and can quit, but, I might want to make a more advanced sudoers file, and know what's wrong, so that I can avoid it in the next version of that. I have a complex structure, which is meant to give exactly the permissions I desire. I want to go for broke! My smb.conf, is good enough now, but sudoers needs a lot of work, then done! I might come back and ask (in another thread), how to enable sudoers when I don't have it configured yet by default, like on Mageia. I will probably use that or SuSe, when I redo my servers. Thanks! Sorry for the trouble!

Just in case it changed:

I DO have a theory, from research! You know how microsoft AD, LOVES nested groups? My theory is that although newer versions of SSSD tolerate them, samba doesn't like them. I'm taking a break, then if no other suggestions, ill try to prove it.

des_a · 03-19-2023, 08:35 PM

I could have both types of groups in AD, one for unix/linux, one for windows, if i wanted, if that's the case.

des_a · 03-20-2023, 12:35 PM

I've just been reminded about "groupmap", which I "think" might be the problem, maybe. I HAVE worked with samba many times before, but not for this. I've mainly been making an NT4 style DC, and a standalone server, equivalent to Windows 10 being a server, as part of a workgroup. This is new territory, and eventually, I will recreate AD with samba, which in real life, and not school "extras", will be a new experience too. i definately have to work more on servers, at some point, as they need a lot of work.

des_a · 03-23-2023, 11:06 AM

I broke something, if I need to, back to basics...

des_a · 04-04-2023, 11:51 PM

OK. Back to this problem. I'm going to first revert, to my most working state, and go from there.

des_a · 04-05-2023, 01:26 AM

Appearently, I'm having two new problems:

1. There is some sort of package mismatch error. I guess this is why people recommend on Ubuntu, doing "sudo apt-get update && sudo apt-get upgrade", before going on.

2. The clocks are too far off. I've seen one post about this, I'll now have to either, set clocks manually, or find the article, again, which tells how to get the clocks right. I opt to try the second first.

Fixed the first in my scripts. I guess I could have just redownloaded the ISO, then done it, but I'm trying to do less work. Adding a line or two in my programs, actually seems like less work. This could be why it sundenly stopped working before. Since I think I fixed the first, now on to the second problem.

des_a · 04-05-2023, 01:28 AM

I guess though, I may pick up tommorrow, and not finish tonight. It's getting kind of late tonight.

des_a · 04-12-2023, 02:14 AM

OK. Great start. I may want to modify especially sudoers in the future. However, for now, I made it work. Everything is as follows:

configure.sh - Used for initial configuration

Code:

#! /bin/sh


echo "Update to latest version..."
apt update && apt upgrade
flatpak update
sleep 11
echo


echo "Doing initial configuration..."
apt install vim dos2unix
sleep 11
echo

echo Fixing time servers...
sudo cp -f /usr/bin/timesyncd.conf /etc/systemd
systemctl restart systemd-timesyncd
sleep 11
echo

timesyncd

Everything else, should be as last posted.

des_a · 04-12-2023, 02:21 AM

OK. So now it seems to be working and reproducable. I just reproduced it with a pretty clean state. It's joined. It took a few times to logon, but I think that's only because I typed things wrong. The only thing I'd like to still do for it, is to synchronize the clocks to the ntp server before I try to join the domain. I'd also like a server side change to change the AD server so it knows about my ntp server. Not doing so could be asking for trouble.

I can also maybe redo my network stuff now, and try to rebuild my servers, and probably should, but that's another story. If I could learn the above, I'm definately good enough. By the way, sudo does work the way it's intended now!

des_a · 04-12-2023, 02:22 AM

Forgot the map-groups file!

OK. Update time!

I changed the server, so it knows about my ntp server, by gpo in domain controllers ou. Whew! Done. Now the other change. I'm going to call it good enough for now, unless in the future, I have time issues with this stuff.

So...

SOLVED!
