root@smb:~ #
vi /etc/krb5.conf # create new [libdefaults] # specify Realm default_realm = SRV.WORLD # add to specify Realm and Hostname of AD [realms] SRV.WORLD = { kdc = fd3s.srv.world admin_server = fd3s.srv.world }
root@smb:~ #
vi /usr/local/etc/smb4.conf # create new # replace [realm] and [workgroup] for your environment
[global]
kerberos method = secrets and keytab
realm = SRV.WORLD
workgroup = FD3S01
security = ads
template shell = /bin/sh
winbind enum groups = Yes
winbind enum users = Yes
winbind separator = +
