Scenario: A Citrix Administrator has configured an Authentication, Authorization, and Auditing (AAA) action 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?
The policy expression that will allow all users access through the vServer is 'ns_true'. In Citrix ADC, 'ns_true' is used in policy expressions to match all requests, effectively allowing unrestricted access. Other options like 'ns_disallow', 'ns_false', and 'ns_allow' do not serve this purpose. Thus, 'ns_true' is the correct expression to allow all users access through the vServer.
C ? The expression is ns_true not ns_allow i think. Here a link : https://support.citrix.com/article/CTX219069
