Is ICA proxy supported with XenDesktop RC6 iApp with APM VE Strongbox license ?

Bruce,

It is not a license limitation. You are limited to 10 concurrent user sessions with APM Limited, but the ICA proxy functionality is there.

If things are not working, I suggest you turn up VDI debugging by running this command from the CLI:

tmsh modify sys db log.vdi.level value debug

Then try to launch an application and check /var/log/apm for detailed info. If you are not able to figure out the issue from /var/log/apm, please work with your F5 SE to open a support case and upload qkview of the box to iHealth.f5.com
