Contents Bypass Authentication for certain sites Outline Squid Configuration File a more complex example Advanced configuration Outline A very common setup in forward proxy design calls for two different access classes: some destinations should be available to all users all other destinations should require users to authenticate Squid allows for this kind of setup, by simply setting your access-lists in the right order.

Squid Configuration File First recommendation is to get acquainted with the basic notions of how to configure squid to properly authenticate. You may also want to check. For instance you may want to have two different user groups let's call them GroupA and GroupB and three classes of sites: one class which must be accessible to unauthenticated users, one which must be accessible to users from GroupA and one which must be accessible to users from GroupB.

Notice that nothing prevents user groups or sites lists from overlapping. Groups are kept in the squid configuration itself, using auxiliary files. This vivitar versa camera setup lead to very subtle differences in behaviour. The difference is what happens when someone tries to access some site which is neither in sitesA nor in sitesB: while with the former example they would get a flat-out access denial, with this change they will be asked to provide a password.

They still get no access, but the way they are denied is different. As soon as they step outside whitelisted sites, they will be asked for authentication before they were only asked for it if they tried to access a protected resource. ConfigExamples Authenticate Bypass squid-cache wiki.

Does Squid cache authentication lookups? Are passwords stored in clear text or encrypted?

How does Proxy Authentication work in Squid? If the header is present, Squid decodes it and extracts a user credentials. The user agent browser receives the reply and then attempts to locate the users credentials.

Sometimes this means a background lookup, sometimes a popup prompt for the user to enter a name and password. The name and password are encoded, and sent in the Authorization header for subsequent requests to the proxy. However, base64 is a binary-to-text encoding only, it does NOT encrypt the information it encodes. This means that the username and password are essentially "cleartext" between the browser and the proxy. Therefore, you probably should not use the same username and password that you would use for your account login.

Authentication is actually performed outside of main Squid process. When Squid starts, it spawns a number of authentication subprocesses. This technique allows you to use a number of different authentication protocols named "schemes" in this context.

When multiple authentication schemes are offered by the server Squid in this caseit is up to the User-Agent to choose one and authenticate using it. By RFC it should choose the safest one it can handle; in practice usually Microsoft Internet Explorer chooses the first one it's been offered that it can handle, and Mozilla browsers are bug-compatible with the Microsoft system in this field.

In addition to the well known Basic authentication Squid also supports the NTLM, Negotiate and Digest authentication schemes which provide more secure authentication methods, in that where the password is not exchanged in plain text over the wire. Notice that helpers for different authentication schemes use different protocols to talk with squid, so they can't be mixed.

The Squid source code bundles with a few authentication backends " helpers " for authentication. POP3: Uses an email server to validate credentials.A proxy server has many use cases. The best way to configure a proxy server is by using the Squid proxy.
