Supported Databases for Virtual Apps and Desktops (XenApp & XenDesktop) AND Provisioning (Provisioning Services)

Citrix is committed to ensuring that our products function with the latest Microsoft SQL databases. Citrix supplies reasonable efforts to ensure compatibility with upcoming database releases. New versions of supported databases released after our products have been released, must work. However, Citrix recommends creating a test environment to ensure there are no unforeseen issues related to changes made to the new version or update of the third-party product. Individuals wishing to use the new release with current Citrix products must perform their own testing before using the platform. Citrix does not support any BETA versions of third-party products.

Note:

  • This document will be updated periodically as new information becomes available.
  • The Cumulative Updates for SQL versions are not called out explicitly. They are an extension of the product and supported.

In StoreFront 3.5 this is added in GUI, however earlier we used to do same by editing the config file:

This is configurable via web.config under the Receiver for Web site, normallyC:inetpubwwwrootCitrixStoreWeb. Open this file in your favorite text editor and locate the following segment:

<uiViews showDesktopsView=”true” showAppsView=”true”

defaultView=”desktops” />

Change the value of defaultView to be apps:

<uiViews showDesktopsView=”true” showAppsView=”true”

defaultView=”apps” />

Desktop Studio Error: “Can't Get License Info”

The license server can be registered with XenDesktop either when XenDesktop is configured, or through the Change license server action on the Licensing node in Desktop Studio.

When the administrator specifies the address of the license server, Desktop Studio attempts to discover the License Configuration Service to allow more reading of license usage.

The error “Can’t get license info” appears if Desktop Studio cannot detect the License Configuration Service. The error does not signify that XenDesktop is not functioning as expected or that the users cannot connect to their desktops and applications.

For administrator authentication issues, only full administrators can connect to the License Configuration Service. Local administrators of the license server machine are implicitly full administrators of the License Configuration Service installed on that machine. Other full administrators can add the new administrators to the License Configuration service.

Some administrators setup on the License Configuration service might still experience problems when connecting to the service. This is generally because of the domain setup issues. The License Configuration Service uses Active Directory (AD) authentication to approve which users are allowed to retrieve license information. For this authentication process to work, either the license server must be in the same domain as the XenDesktop site, or there must be a two-way trust between both domains. Refer to Microsoft documentation for details on configuring trust relationships.

2. Select Encryption Keys.

User-added image

3. Select Create Key. For improved performance, it is recommended to create the KMS key in a similar region as your ShareFile zone. For example: if using the US-West Citrix-managed StorageZone, create the KMS key in the US-West region.

4. Provide a Name/Description for the Key and assign any Administrators.

5. Under External Accounts, enter the ShareFile AWS Account Information. This allows ShareFile to access the key for the purposes of Encrypting and Decrypting files.

Note: Please contact ShareFile Customer Support to obtain the external account ID.

User-added image


6. Obtain the ARN of your encryption key and provide it to ShareFile. For example: provide the information in the following format:

arn:aws:kms:us-east-1:123456789012:key/b9454537-1892-424c-9326-2789700839f9


Configure CloudTrail Logging

1. Click CloudTrail in the Console menu.

Validating Key Operations

A. Test Disabling the KMS Key

  • Perform some test uploads and downloads to your Zone
  • From the AWS Console, select your key and choose Disable.
  • Wait a few minutes and then try to upload or download to your Zone once more. You should see the operations fail.
  • Re-enable the KMS key and verify that you can upload and download successfully.
User-added image

B. Test Revoking the ShareFile External Account

WARNING – Do not delete the Master Key on AWS, as that could permanently revoke access to ShareFile data encrypted with the Master Key.

  • Edit the KMS Key and browse to External Accounts
  • Select the “Remove” option to revoke ShareFile access to this key (save the value before deletion)
  • Wait a few minutes and then attempt to upload or download. You should see the operations fail.
  • Re-add the external account.
  • Wait a few minutes and then reattempt uploads or downloads. The operations should be successful.

C. Verify Activity via CloudTrail Logs

  • After performing some uploads and downloads, check CloudTrails activity. (may take ~10 minutes to populate)
  • Verify you can see Activity such as username, filename, and operation (Upload or Download).
  • Note – File Names that contain special characters or Unicode characters will appear as URL-encoded in the CloudTrail logs. To view the filename, you can use a URL decoder.
