Recently we had the present surprise to have Arrow ECS to play for Santa and provide us with nice 3G enabled iPADs. The goal was to demo and show of as much as we can using these nice devices.
So first step integrate with our Citrix Demofarm.
The basic steps are pretty easy :
- XenApp farm newer then 5 (or 4.5 with Rollup pack 6)
- XenDesktop 4 or newer
- preferably Web Interface 5.3 with a XenApp Services Site configured pointing to your Citrix Access Gateway
And yes that’s it … nothing more … although it didn’t work …
First error we received on the Ipad was Server Certificate not trusted.
That was an easy one just like with other CAG implementations we just have to make sure the private root public certificate is present on the iPad. You can do this by mail or use the Iphone Configuration Utility to make a nice profile (you can add and preconfigure your wireless networks in there too if you like).
You can find this util here : http://www.apple.com/support/ipad/enterprise/ (the util exists in a Windows version as well)
So Root Certificate imported but still errors :
“Can not make a secure server connection” or if you try to reach a Web Interface Site on the same server you get “Safari cannot open the page because it could not establish a secure connection to the server”.
So I enabled syslogging on our demo Netscaler VPX / CAG Enterprise, and there was nothing to see.
So the iPad couldn’t even reach the CAG it seems. So after further investigation, did a little wireshark, I came with the idea to reducing the number of “Ciphers” that are offered by the CAG or Netscaler VPX.
The configured Ciphers are all the various encryption algorithms the Netscaler supports and it might be that the list is too long for the iPad to choose from and so getting a secure connection failure.
So in the CAG VIP properties on the Netscaler VPX, I clicked the button “Ciphers” removed all of them and just added the group “Medium”.
I saved the settings and yes it works ! So now we are happy iPad – Citrix Receiver users.
One nice other thing about iPad and Citrix Receiver is try to tab with 3 fingers on the screen while connected, it’s a handy shortcut to the keyboard.
