Hi Andrew, Rowland, team,
After checking the difference of our different AD forests'
configuration, we figured this issue out finally.
There is an attribute "Do not require Kerberos preauthentication"
on AD users, someone in our team checked this option on all users,
after un-check this option, we can join AD domain normally.
Appreciate all your suggestions!
