How to restrict Active Directory Users/Group to login to Linux client?

Issue

Have a server that allows AD users to login, it creates their home directory, and they can use the system as intended.

• Would like to limit SSH to a certain group of users.
• Below is the pam entry:

#%PAM-1.0
auth       required     pam_sepermit.so
auth       include      password-auth
account    required     pam_nologin.so
account    include      password-auth
password   include      password-auth
# pam_selinux.so close should be the first session rule
session    required     pam_selinux.so close
session    required     pam_loginuid.so
# pam_selinux.so open should only be followed by sessions to be executed in the user context
session    required     pam_selinux.so open env_params
session    optional     pam_keyinit.so force revoke
session    include      password-auth
session    required     pam_mkhomedir.so skel=/etc/skel umask=0077
