Authentication 
To make sure that every single client authenticates against the 2X 
VirtualDesktopServer  to retrieve the list of published applications enable 
‘Always require user credentials for application list’ checkbox. 
To authenticate against a specific domain/workgroup you have to select the 
‘domain’ radio button and enter the domain/workgroup required. 
In case you want to select a new domain for authentication, simply click on 
‘…’ button and select the new domain to be used.  You can also use the 
‘Default’ button to choose the default domain/workgroup used for 
authentication. 
Select ‘All Trusted Domains’ if you want to authenticate  with any trusted 
domain/workgroup.  
By default ‘use client domain if specified’ is checked and this option will allow 
the user to specify the domain to authenticate in their client (2X Client – 
General options - Domain). If the client does not specify any domain, and this 
option is enabled, the authentication is done with the domain specified in the 
Authentication panel as displayed in the above figure. 
When this option is disabled, the clients will only authenticate with the domain 
specified in the domain field of the authentication panel on the server side. 
We recommend you selecting ‘Always require User Credentials for application 
list’ so that all users must authenticate before acquiring the application list. 
Make sure to click ‘Apply’ to activate the above settings.  
NOTE: In case that you want to make authentication with a workstation which 
is not joined with a domain you can also authenticate with the local users of 
the workstation. In order to specify authentication with such a workstation you 
must enter [workgroup_name] / [machine_name]. Therefore if you would like 
to authenticate against a machine named ‘SERVER1’ and  member of 
workgroup named ‘WORKGROUP’ you would have to enter: 
WORKGROUP/SERVER1 in the domain field. 
NOTE:  In order to avoid user filtering problems, it is suggested to use the 
NetBIOS name instead the FQDN in the domain field.
