Evaluating Identity Group Membership
The Web Proxy sequentially reads through each Identity group in the Identity policies table. It compares
the client request status to the membership criteria of the first Identity group. If they match, the Web
Proxy assigns the Identity group to the transaction.
the client request status to the membership criteria of the first Identity group. If they match, the Web
Proxy assigns the Identity group to the transaction.
If they do not match, the Web Proxy compares the client request to the next Identity group. It continues
this process until it matches the client request to a user defined Identity group, or if it does not match a
user defined Identity group, it matches the global Identity policy. When the Web Proxy matches the client
request to an Identity group or the global Identity policy, it assigns the Identity group to the transaction.

If at any time during the comparison process the user fails authentication, the Web Proxy terminates the
request. For more information about how authentication works with Identity groups, see

After the Web Proxy assigns an Identity to a client request, it evaluates the request against the other
policy group types. For more information, see the following locations:

Understanding How Authentication Affects Identity Groups
Requiring authentication for users can help your organization control access to the web for groups of
users. AsyncOS allows you to create multiple Identity groups and define the membership criteria based
on authentication requirements.

on authentication requirements.
When authentication is required for an Identity group, a gold key icon appears next to the Identity group
name in the Policies table, as shown in

Identity Groups that Require Authentication
To define authentication requirements for an Identity group, you can choose an authentication realm or
sequence that applies to the Identity group.

Note
You can specify the authorized users when you use the Identity in a non-Identity policy group.
Consider the following rules and guidelines when creating and ordering Identity groups:
•
Identity group order. All Identity groups that do not require authentication must be above Identity
