Actually 0904.huawei.com is just one of my test domain. I also built domain naned vds.huawei.com.  Same problem exsts. Besides, samba 4.5.16 doesn't have this issue.
I still doubt that some setting changed, such as encrypt method permission... After all, the log renainds password is wrong.Do you have any other clue?
