Hi !! We are having some problems with our domain controllers that is slowing down squid during peak ours, due to ntlm authentication. We considered changing the value of Max_Challeng_Reuse from 0 to some higher value, in order to decrease the load on the domain controllers coming from squid, but I would like to know what are the possible consequences, specially regarding performance, before actually commiting this change. Can anyone send me informations about it? Thanks in advance, Carlos.
