Hey All, I'm a relatively new to Linux and squid. I've only really been using both for about 2 and a half months now. Apologies as I'm sure this has probably been asked before. I have an ubuntu server (6.06) with apache 2.2.6 compiled, and running on the box. I also have squid 2.6, complied and running fine. a few days ago thanks to browsing many many forms I've also figured out how to get my squid proxy server to authenticate Via LDAP so when a user opens a web browser they have to type there LDAP Logon details to use the Internet. I've been asked by the powers that be, can we now make the proxy server "invisible". what we want is when a user opens a web browser it will still use their LDAP logon details to authentication but with no users intervention at all. IE. from the users perspective they open a web browser and they can browse the web but in the background when they open the browser the squid proxy server automatically authenticates them against their LDAP details. The reason for this is i work in a college so we want to make the proxy server as seamless and "invisible" as possible to all staff and students. If they don't know the proxy server is there they wont try to bypass it. I've asked the "Internet guru" (google) to find me an answer and the closest thing I've come up with was a website getting using perl scripts to authenticate against LDAP but im sure the perl script was written for novell. This is the website: http://www.novell.com/coolsolutions/feature/17777.html But I haven't really come up with much sofar. I've also had a look on the FAQ list and the mailing list archive for similar questions regarding this but I couldn't find anything about it. I'd be really really grateful for any help Thanks a mill Anthony
