In a specific situation but with not necessary rare configuration you get the following error message with Android Citrix Receiver: "Error has occurred while connecting. Check your server address and data connection."

Before I go into my specific issue with the error you should check out the following Citrix article:

Identity Provider (IdP) is what you need with ShareFile and often used with Microsoft Active Directory Federation Service (ADFS) as IdP. ShareFile and XenMobile are seamlessly working together when using XenMobile as IdP. This would break the seamless integration with Windows Clients using ShareFile Outlook Plug-In, Desktop Sync etc. The solution is to use both IdP's at the same time and the reason calling it dual IdP. With ADFS 2.0 you cannot export the signing certificate with the private key and even if you could it would only be good for one year before ADFS automatically would roll over to a new certificate.

Why bother with SMS when everyone has a smartphone these days? The point is when a new employee gets a brand new phone of the shelf it's not configured what so ever. Now you do know the phone number but that's it. Therefore, email is not an option and you're left with SMS to onboard the employee using XenMobile.

In my opinion, Citrix Director is the best peace in XenDesktop 7 if you don't see it as a replacement for EdgeSight. That is what Citrix does, calls it an EdgeSight replacement but again, in my opinion, was a mistake to do. For customer who really used or still use EdgeSight, the "New" EdgeSight is more or less a joke. For those customers, Citrix must come up with something else or acquire another software or company for it like "Nexthing".

Again, Director "EdgeSight" is a nice integration but here is my list that could be better and let's hope Citrix will do something about it.

Upgrading the Citrix Virtual Delivery Agent (VDA) seems to be more and more a problem than an easy process. I don't understand it anyway why the VDA cannot be pushed by the DDC on request. Meanwhile, we have to fight Citrix and Microsoft to get the VDA installed or upgraded. Here are points you should follow to be successful.

Time is an important value for authentification and other things and the reason to ensure from the beining it's working in your setup. Deploying Citrix Netscaler in a High Availability (HA) paair is very common, especially when we are talking about the VPX editions. First thing you should ensure is that the time between both Netscaler are in sync.
