Scenario: A Citrix Architect observes the following configurations while performing an assessment of a Citrix ADC deployment:

Citrix Gateway virtual server nsg-dmz-001 is configured in ICA Proxy mode.

The authentication method used is Plaintext LDAP.

The session policies bound are configured to integrate with StoreFront in ICA proxy mode to perform Single Sign-on.

The connection to LDAP server is performed using SNIP by Citrix ADC.

To meet the new design requirement the architect needs to change the SNIP used for communication with LDAP servers.

Which AAA parameter must the architect verify to update the source IP address for the communication from Citrix ADC to the LDAP server?
