If the user is not in a specified internet access group, they will be blocked.Īs stated above, most customers will immediately swap out the default authentication “back-end” to use their internal resources (such as Active Directory via NTLM).ĭepending on your directory structure and company policy you may need to define the groups which are allowed internet access. The third ruleset is meant for restricting web access to a list of user groups. This ruleset will only apply if the user has not already authenticated (Authentication.IsAuthenticated equals false) and they have not already failed authentication (Authentication.Failed equals false). The authentication “back-end” used by default is the internal “User database”, this is almost always immediately swapped out for NTLM (see “expected or likely modifications”). The default ruleset has rules for creating exceptions based on the client IP and the destination URL. What it looks like (by default) Direct Proxy Authentication and Authorization When using NTLM or Kerberos direct proxy authentication is promptless (provided the browser supports it, Safari doesn’t for example). This ruleset can be found in the ruleset library. The recommended authentication front-end for Direct Proxy is “Direct Proxy Authentication and Authorization”. When you select a ruleset to add, it may prompt you stating that conflicts exist, simply click “Auto Solve Conflicts” and then choose the option that works best for you (solve by referring to existing objects, or solve copying and renaming to suggested).Ĭommon Authentication Examples by Deployment Method Direct Proxy It can be accessed from within the rulesets tab under the “Add” button. The ruleset library is a place to find example rulesets for use within your configuration. The type of authentication front-end chosen dictates how the Web Gateway is to interact with the user (this may mean the user gets prompted). The Authentication “back-end” has to do with how the Web Gateway validates those credentials. Authentication server requires a trust relationship with the browser.Īs described above, the Authentication “front-end” has to do with how Web Gateway obtains the users credentials. Authentication server is a session based authentication. Direct Proxy Auth vs Authentication Server Auth (for Transparent Setups)ĭirect proxy authenticates every connection, only browser change required is to the proxy settings. This article does not discuss how Web Gateway validates the credentials also known as authentication “back-end” (example of an authentication back-end would be NTLM, Kerberos, LDAP, eDirectory, etc…). This document will only discuss how the Web Gateway obtains the credentials also known as the authentication “front-end”. This document will discuss the most common examples, and show the ruleset/rules in context for reference. I am writing this document as there is often a lot of confusion about what kind of authentication should be performed based on the type of deployment chosen.
