We'd discussed this a while ago. Currently Sharepoint defaults (well technically IIS) to NTLM authentication. The problem is that NAM doesn't support NTLM, so you have to reconfigure Sharepoint.
Note: We're not necessarily talking about NTLM from the PC to the web browser to NAM. What we're referring to is if NAM can take the already authenticated user and pass the credentials to Sharepoint via NTLM.
