Hi, am I right that ntlm_auth (delivered with squid) supports only "LM" and neither "NTLM" nor "NTLMv2" ? I'm asking because all my Win-Clients can transparently access Inet via proxy, if local security settings are "send LM and NTLM". When security setting is "send only NTLM" (as the default for e.g. Win Server 2003 Std) cache access is denied. Thanks Chris
