We use NTLM authentication, but the new windows 7 beta (yes, its beta but its nice to know of potential issues before they get widely released) seems to be having trouble authenticating. A standard authentication from XP provides the following in /var/log/squid/cache.log: Got user=[912058] domain=[UK] workstation=[LONW037057] len1=24 len2=24 An authentication from Windows 7 beta is shown below: Got user=[009340] domain=[UK] workstation=[LONW032292] len1=24 len2=332 Login for user [UK]\[009340]@[LONW032292] failed due to [Invalid parameter] I see the different "len2" information at the end, so I assume MS has extended something. The packages we are running are squid-2.6.STABLE20-1.el5 and samba-common-3.0.28-1.el5_2.1. I am curious whether a package upgrade will fix the problem, if this windows 7 thingy has introduced an incompatibility that we expect MS to fix with their next release or if this is a valid request that uses a hitherto unused part of the protocol and therefore we should allow for it.
