What is the current authentication protocol for CRM 4.0 on-premise?

The infrastructure team wants to update the authentication protocol 开发者_运维问答to NTLMv2 and Kerberos. Will this affect CRM 4.0 on-premise installation. What would need to be changed in order to use the updated protocols. I am having a difficulty locating any official documentation on what the current authentication protocols are for CRM on-premise.

I don't think this will be an issue. Vista ONLY uses NTLMv2 and CRM runs fine on it. I can't, however, find any official statement from Microsoft but my assumption is that you'll be fine updating.
