Using Previous Versions of Citrix Receiver

If previous versions of Citrix Receiver are installed, Citrix recommends you uninstall these versions before installing Citrix Receiver 1.0. Installing Version 1.0 does not uninstall or automatically update previously installed versions.

SSL Certificates

To connect to a XenApp farm, users' iPhone or iPod touch devices must have a Configuration Profile installed that includes the certificate for the Web server hosting the farm's Program Neighborhood Services site or XenApp Services site. You can obtain this certificate from your browser's certificate store.

Note: Citrix Receiver does not support wildcard certificates.

For information about creating Configuration Profiles and distributing them to users, visit the Apple Web site.

SSL VPN Connectivity

Citrix Receiver supports connecting to a XenApp server farm through the following products or components:

• Citrix Access Gateway Standard Edition
• Citrix Secure Gateway when used as a proxy in normal mode

Connectivity through Citrix Access Gateway Advanced Edition or Enterprise Edition is not supported. Connectivity through Citrix Secure Gateway when used as a proxy in relay mode is not supported.

Authentication Methods

Citrix Receiver supports authentication through Access Gateway using the following methods:

• Domain authentication
• RSA SecurID
• Domain authentication paired with RSA SecurID

For more information about using these authentication methods with Access Gateway, see the Access Gateway Standard Edition Administrator's Guide.

Starting Citrix Receiver for the First Time

When users start Citrix Receiver for the first time, they are required to enter information about the XenApp farm hosting the resources they want to access. To ensure users can connect successfully to the XenApp farm, be sure to distribute the following information:

• The location of the Program Neighborhood Services or XenApp Services site hosting resources; for example:
  http://servername/Citrix/PNAgent/config.xml
• Domain name
• The product edition and authentication method, if using Access Gateway

Users can turn on the Sign In Automatically option so this information will be remembered the next time they start Citrix Receiver.

If the Sign In Automatically option is turned on, users cannot access the Account Settings screen later. To access the Account Settings screen, turn off this option by tapping Settings > Citrix. Then, restart the Citrix Receiver to view the Account Settings screen.

Troubleshooting Citrix Receiver for iPhone

Disconnected Sessions

Users can disconnect from a Citrix Receiver session in the following ways:

• Pressing the home button on their iPhone or iPod touch device
• Tapping the Back to Apps button in Citrix Receiver

If this happens, the session is left in a disconnected state. Although the user can reconnect at a later time, you can ensure disconnected sessions are rendered inactive after a specific interval. To do this, configure a session timeout for the ICA-tcp connection in Terminal Services Configuration. For more information about configuring Terminal Services, refer to the Microsoft Windows Server product documentation.

Known Issues

Applications published with 128-bit encryption

When using Citrix Receiver to access an application published with 128-bit encryption, the application does not open or operate as expected. This is due to a limitation with the iPhone operating system. Applications published with basic encryption open and operate normally when accessed with Citrix Receiver.

Using non-ASCII characters with published applications

When using Citrix Receiver to access a published application, the following limitations exist:

• If the application is published with a name containing non-ASCII characters, the application does not open.
• Entering non-ASCII characters, such as Korean characters, in published applications does not work as expected.
  To mitigate these limitations, ensure that:
• Your farm consists of one of the following configurations:
  • Citrix Presentation Server 4.5 with a Program Neighborhood Services site configured on a non-English operating system.
  • Citrix XenApp 5.0 with a XenApp Services site configured on a non-English operating system.
• The Microsoft IME toolbar is not minimized in the published application.
  To enter non-ASCII characters in a published application using the iPhone's QWERTY/Pinyin keyboard, perform the following steps:
  1.Using Citrix Receiver, connect to the published application.
  2.Tap the Microsoft IME toolbar and select the language you want to use; for example, JP.
  3.Select the language mode in which to enter non-ASCII characters; for example, Hiragana mode.
