I installed ACS3.3 on windows 2003 standard server and it joins Windows 2000 Active Directory. It works normally when it is using Cisco Secure Database. However, it can't authenticate users located in windows 2000 AD. Is my combination supported by Cisco ACS ? Any additional function I need to configure?
Besides, I checked with Document that NTLMv2 is not supported in Domain Authentication. NTLM version is determined by the Domain Controller or the Member Server (i.e. The ACS server)?
Thanks a lot!
Verify that the NT LAN Manager (NTLM) version used is version 1. In the applicable Windows security policy editor, access Local Policies > Security Options, and locate the LAN Manager Authentication Level policy and set the policy to Send LM & NTLM responses. Other settings involve the use of NTLM v2, which Cisco Secure ACS does not support.
