Netscaler 10.x Configuration for Receiver

To allow Primary and Secondary Authentication using Citrix receiver clients the following policies are required. On the Netscaler Access Gateway select Netscaler Gateway then Virtual Servers, click on the required server then Open. Click on the Authentication tab, and create a policy for RADIUS authentication and a Policy for LDAP authentication for the Primary and Secondary authentication. The below assumes that the Primary authentication server is LDAP and the secondary authentication server is RADIUS for methods other than Receiver authentication.
