Citrix Integration

Hello all, we are process of getting the Citrix Integration setup. Going by Websense 7.8.x Configuring user access on Citrix server documentation (page 306), what /which permissions do we add from the Citrix server Access Management Console - Do we add each user that we currently have given Citrix access to or add the Citrix users group? The steps aren't very clear. We are using Citrix XenApp 6.5 and Websense Web Security 7.8.1 Thanks
