Connect to an Active Directory Domain

Use the realmd to connect to an Active Directory Domain. The realmd system provides a clear and simple way to discover and join identity domains to achieve direct domain integration.

It configures underlying Linux® system services, such as SSSD or Winbind, to connect to the domain.

realm join adserver.ad.gpfs.net -U Administrator
realm permit -g hadoop@AD.GPFS.NET

Configure the sudoers file to add below line:

%SudoNO@ad.gpfs.net  ALL=(ALL)   ALL

Configure /etc/sssd/sssd.conf file with the following changes:

use_fully_qualified_names = False
fallback_homedir = /home/%u

Restart sssd service after changing the configuration file.

systemctl restart sssd
