Hello, i have a big problem. We are using Squid Cache: Version 2.3.STABLE4-hno.CVS on SuSe Linux as proxy server with ncsa_auth. Since a few day's we have a problem with authentication. It works all fine a lot of hours and then a lot of poeple calling, that they can't access the internet. They will enter their username and password and the popup will come back. After 3 failed logins they will get the error message "Cache Access Denied" Then they will try again for 3 or 10 times and the login will work again. This happens maybe 5 times a day. We have 1500 users on two proxy-servers. I hope someone can help. Jens
