Linux join domain

sudo apt -y install realmd sssd sssd-tools libnss-sss libpam-sss adcli samba-common-bin oddjob oddjob-mkhomedir packagekit
sudo hostnamectl set-hostname SETNEWNAMEFORYOURMACHINE
realm join test.local
sudo nano /etc/pam.d/common-session
------------------------
pam_mkhomedir.so skel=/etc/skel umask=077

if you want to omit domain name part for the username – go to

sudo nano
/etc/sssd/sssd.conf
---------------------------------------------
use_fully_qualified_names = False
---------------------------------------------
Save the file and reboot sssd

For XRDP support add the last to lines of this sample sssd.conf:

[sssd]
