Hello all,

First of all I should declare that I am a Linux , however, I can be swayed from the Dark Side.

I am having some trouble on a clients corporate network. They are using a Linux Squid box as the proxy server for a Windows NT domain. Generally the user authenticates to the NT Domain and if valid Internet Access is granted. However, on some of the clients (ranging from Windows 95 to Windows 2000) are continually prompting to authenticate when trying to access the internet through the Squid proxy box. The authentication between NT and Linux does not appear to be occuring. The problem is not happening to all clients, and their does not seem to be any real pattern to the problem.

Any ideas on my problem would be greatly appreciated.

Feel like posting the acl area of your squid.conf file?

Here is the acl area of the squid.conf file. Some details have been changed just to shield the client.

acl QUERY urlpath_regex cgi-bin \?
acl all src 0.0.0.0/0.0.0.0
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255

acl CONNECT method CONNECT
acl <client>proxy proxy_auth REQUIRED
acl <client>allow proxy_auth "/usr/local/squid/etc/authority/INTERNET_ACCESS.allow"
acl <client> dstdomain <client domain>
acl all-servers dstdomain all

Also other details are:
Distribution: Redhat 7.3 running kernel 2.4.7-10
Squid Version: Squid 2.4STABLE3

Thankyou in advance for any ideas.
