How can I find the IP of Active Directory Domain Controller(s) from Unix?

Question

I can get the nameserver via NSLOOKUP on a Windows machine and get an AD DC via a WMI VBS script, but I can't use the VBS script from a Unix server ( which can ping the nameserver). I'd like to use Java to obtain all the Active Directory domain controllers from a Unix box. Is this possible?

Answer 1

I'd suggest you to look into java.net package which contains various classes like INetAddress, URLConnection and various socket classes that you might find useful.

Answer 2

Yeah, you can connect to it like standard LDAP. You can use the OpenLDAP Library:

Answer 3

If you can query the DNS Server, can't you perform a query for its service records to discover computers that can act as Domain Controllers?

That's how Windows Workstations find their candidate Domain Controllers.
