I have setup Squid to perform authentication via NTLM and everything is working fine with the exception of 1 odd error. At random times throughout the day, and for no apparent reason, an authentication popup will be presented to the user. Merely clicking "cancel" will allow the user to view the site. The proxy server has not yet been deployed throughout the organization and therefore only has a very minimal load on it at the moment, yet it does this random authentication thing. Does anyone have any ideas as to what might be causing this to happen? -- Scott Jarkoff
