I have a webwasher cluster and ins integrated with AD for domain authentication. Whenever the Windows domain controllers gets rebooted, browsers (IE, Chrome and Firefox) will prompt for authentication. In the webwasher, i have defined both the Domain controllers so that if one is down, it will redirect to other for authentication.But still the users are prompted for authenticatuion. How can i configure so that it wont prompt for authentication unless both DC's go down? FYI, we have 4500B model and SW 18.104.22.168.0.
What kind of authentication are you doing (I'm not asking about NTLM)? Is there a reason you have NTLMv2 disabled?
See this document for what I'm asking (direct proxy or authentication server)
If you are using the auth server, do you have the auth server URL trusted in the browsers (this is covered in the guide)?
