I am new to Linux. I am trying to join a Ubuntu 16.04 server to a Windows domain. I came across this article. I used a similar article for 14.04 which worked with very little issues.
When I run sudo apt install krb5-user samba sssd ntp I get error messages :
adduser: Warning: The home directory `/var/lib/sss' does not belong to the user you are currently creating.
Warning: found usr.sbin.sssd in /etc/apparmor.d/force-complain, forcing complain mode
Warning failed to create cache: usr.sbin.sssd
Job for sssd.service failed because the control process exited with error code. See "systemctl status sssd.service" and "journalctl -xe" for details.
sssd.service couldn't start.
I am not sure why this is occurring.
