I have a setup with RHEL 7.4 machines that connect to Active Directory (AD) running on a Windows Server 2016 Datacenter Edition. The Linux machines are in direct integration with the AD.
Since Identity Management for Unix (IDMU) & NIS Server Role is removed from this version of Windows, the solution is to use
sssd to autogenerate UID and GID numbers.
I am not able to understand how the autogenerated GID will be mapped to the actual group on the Linux machine.
For example, if user
john is a member of
LinuxGroup in the AD and is logged in and that should be mapped to group
localgrp on the Linux machine, how will this work out? How would he get
linuxgrp privileges if the autogenerated GID is 500 but
localgrp GID is 10 on the Linux machine?
To have only central management of users, we are not allowed to add users directly in Linux i.e. in
