#server ntp.your-provider.example
server your.domain.controller
# /etc/init.d/ntp start
Edit Your file /etc/krb5.conf
# cat /etc/krb5.conf
[libdefaults]
default_realm = DOMAIN.NAME
clockskew = 300
[realms]
DOMAIN.NAME = {
kdc = your.domain.controller IP Address
admin_server = your.domain.controller IP Address
}
Edit Your file /etc/samba/smb.conf
# cat /etc/samba/smb.conf
[global]
realm = DOMAIN.NAME
workgroup = domain
security = ADS
idmap uid = 10000-20000
idmap gid = 10000-20000
template shell = /bin/bash
template homedir = /home/%D/%U
winbind use default domain = yes
[homes]
valid users = %U
check your modification with
# testparm
and then
# mkdir /home/DOMAIN
Then edit the /etc/nsswitch.conf file:

# wbinfo -u |xargs getent passwd
