Resolve Kerberos Authentication Issues

To fix issues related to Kerberos authentication, complete the following procedure:

1. Disable Kerberos on the ICA Client.

2. Set SSPIEnabled = Off in the wfclient.ini file in the \Program Files\citrix\ica client folder and in the user’s profile in the \Documents and Settings\username\Application Data\ICAClient folder.

3. Close and restart the ICA Client.

Problem Cause

Licensing issues might be preventing the user to connect to the application Issues with Kerberos authentication.
The error is displayed when pass-through authentication is enabled on the ICA Client.
If explicit authentication is used, the error message is not displayed.

RD Licensing formerly Terminal Services Licensing (TS Licensing), manages the Remote Desktop Services client access licenses (RDS CALs) that are required for each device or user to connect to a Remote Desktop Session Host (RD Session Host) server

Broker Database would have a new table for maintaining RDS CAL as a key/value pair. On a non-Windows client connection to a TS VDA, if a license is checked out, ICA populates the registry entries. Behaviour on following session events is described below:
 

• On Logon or Reconnect:

HKLM\Software\Citrix\MSLicensig\ReplicateCache registry key and corresponding nodes under HKLM\Software\Citrix\MSLicensig registry key to check if any of the licenses has same index as RdsCalId.
 

• On session audit event:

HKLM\Software\Citrix\MSLicensig\ReplicateCache registry key and corresponding nodes under HKLM\Software\Citrix\MSLicensing registry key. For each node under HKLM\Software\Citrix\MSLicensig\ReplicateCache registry key, Stack Control would read license information from corresponding node under HKLM\Software\Citrix\MSLicensing, create a blob of byte array and write license information to the blob.
 

• On Validate event:

Create node and write license information to node under HKLM\Software\Citrix\MSLicensing
