Hi As the linuxbox access the Win2K box running ADS for getting the user authenticated using squid_ldap_auth, when the machine running DNS goes down linuxbox is not able to reach the Win2K box running ADS I suppose. As soon as the DNS system came back to life authentication is working fine. Anyone can tell me more why this happens?
