[Samba] Using net ads user to get child domain users on Samba 4.10.7

[Jeremy]

Hi all,

I have an question about getting child domain users on Samba 4.10.7.
1. I have the command net ads search '(objectCategory=trustedDomain)' -P
and already get the info below:
objectClass: top
objectClass: leaf
objectClass: trustedDomain
cn: hardware.qsan.ad.com
distinguishedName: CN=hardware.qsan.ad.com,CN=System,DC=qsan,DC=ad,DC=com
instanceType: 4

uSNCreated: 13099
uSNChanged: 5427247
showInAdvancedViewOnly: TRUE
name: hardware.qsan.ad.com
objectGUID: ed241fe5-a87a-401b-b28a-b553f408f6e9
trustDirection: 3
trustPartner: hardware.qsan.ad.com
trustPosixOffset: 1073741824
trustType: 2
trustAttributes: 32
flatName: HARDWARE
objectCategory:
CN=Trusted-Domain,CN=Schema,CN=Configuration,DC=qsan,DC=ad,DC=com
isCriticalSystemObject: TRUE
dSCorePropagationData: 16010101000000.0Z

2. But when i use "net ads user -w hardware.qsan.ad.com -P" can't get any
users and i'm sure i can ping hardware.qsan.ad.com.

Error messages: ads_connect: No logon servers are currently available to
service the logon request.

3. Command for "wbinfo -u" can get users from hardware.qsan.ad.com like
"HARDWARE/tim".

Could any one help me to figure out this and i'm so grateful.


Best Regards
Jeremy
