Opened: Feb 06, 2020
Severity: 3-Major

Symptoms

APM has three primary types of session variables: - Per-Session Variables - Per-Flow Variables - Subsession Variables If you attempt to use a per-flow variables (perflow.*) inside of an AAA agent in a subroutine, the resultant variable will appear to be blank, when it should have a value.

Impact

The APM administrator will be unable to use perflow variables in AAA agents in a per-flow policy subsession macro.

Conditions

Usage of perflow.* variables inside some AAA agents such as AD Query/Auth and LDAP Query/Auth inside of a per-request subroutine.

Workaround

To work around this problem, use a Variable Assignment agent to set a subsession variable immediately before the AAA agent, and then configure the AAA agent to use the subsession variable. For example: [Variable Assign Agent] [custom variable]subsession.custom = [session variable]perflow.custom

Fix Information

None
