Session Variables

About session variables

An access policy stores the values that actions return in session variables. A session variable contains a number or string that represents a specific piece of information. This information is organized in a hierarchical arrangement and is stored as the user's session data.

The Current Sessions report in the Access Policy Manager® Reports area displays all session variables for a session. Session variables can be useful in access policies to achieve various results, including:

  • Customizing access rules or defining your own access policy rules.
  • Providing different outcomes for policies based on the values in the session variables.
  • Determining which resources to assign to users (with the Resource Assign action).

About session variable names

The name of a session variable consists of multiple hierarchical nodes separated by periods (.).

It includes the string session, a type, the agent name or the string last, intermediate agent-specific info, node name (attr or result), attribute name

How APM constructs session variable names

Session variables for Active Directory authentication and query

Access Policy Manager® names session variables in the following manner:
  • session.ad.<username>.queryresult = query result (0 = failed, 1=passed)
  • session.ad.<username>.authresult = authentication result (0 = failed, 1=passed)
  • session.ad.<username>.attr.<attr_name> = the name of an attribute retrieved during the Active Directory query. Each retrieved attribute is converted to a separate session variable.
Note that attributes assigned to a user on the AAA server are specific to that server, and not to Access Policy Manager.
