Scenario: A Citrix Administrator configured an authentication, authorization, and auditing (AAA) policy to allow users access through the Citrix ADC. The administrator bound the policy to a specific vServer.
Which policy expression will allow all users access through the vServer?
In Citrix ADC, the correct policy expression to allow all users access through the vServer is 'ns_true'. This is a special built-in expression that is evaluated as true for all requests. It is frequently used for policies that need to match all traffic or users, making it the appropriate choice for this scenario.
"13.1 and AAA" uses the advanced(default) the express is "true." Citrix Gateway takes a "true" expression since it is a classic authentication.
good point
Should be ns_true add authentication localPolicy Authn-Pol-1 ns_true
Tricky one, this is for 13.1 and classic still is mandatory for AAA until 2023 (with exceptions on Traffic policy) https://docs.citrix.com/en-us/citrix-adc/current-release/appexpert/policies-and-expressions/introduction-to-policies-and-exp/advanced-policy-infrastructure.html
C tried to use ture instead of ns_true in ADC 13 and showing invalid rule
add authentication policy Authn-Pol-1 true show authentication policy Authn-Pol-1 Name: Authn-Pol-1 Rule: true Request action: LOCAL bind authentication vserver Auth-Vserver-2 -policy Authn-Pol-1
