We recently created a brand new Citrix Xenapp 6.0 environment with four Windows 2008 R2 servers in our farm.  40 users will be connecting into the environment with a variety of platforms including thin client technology, mobile PCs, and now mobile tablets and phones.  One of the goals in our Citrix Xenapp installation was to support as many platforms as possible.  With Citrix, that is entirely possible with a few tweaks to get things working right.  With mobile devices becoming the preferred computing device, especially tablet PCs, Citrix access has become a frequent request in recent years.

Citrix offers an lightweight application available for iOS, Android, and Blackberry devices called the Citrix Receiver.  This simple app provides you secure access into your companies Xenapp environment.  You can stream published apps and use your desktop on the convenience of a tablet.

During our testing phase, we ran into an issue with iOS 5 devices not accepting our SSL certificate installed on the Secure Gateway server running Windows IIS6.  We experienced the problem on both the iPad1 and iPad2 and also the iPhone 4 and more than likely it affected all iOS devices.  We had reason to believe it was due to our standard SSL certificate authorized through GoDaddy since we had other environments working but with an SSL certificate through another SA.  The problem occured when an iOS device attempted to launch an app or published desktop.  The connection would fail half way and say:

Connection Error:  You have not chosen to trust "Go Daddy Secure Certification Authority", the issuer of the server's security certificate.  Error Number: 183
