Description
Is there any vastool command for finding out which domain controller (DC) Authentication Services client is communicating with?
-
Résolution
"vastool info servers" can only list the servers it knows from Active Directory, but a conclusive way would be to intercept the client-server communication by means of "tcpdump" and examine the packets.

Informations supplémentaires
For example:
Terminal session 1: # tcpdump -i eth0 | grep 3268
Terminal session 2: # vastool -u administrator group rg02 hasmember ru01
Password for administrator@QMXLAB.COM:
ru01 is not a member of rg02
