If you have a user who is not a member of the ‘Domain Users’ group and still requires access to Citrix Password Manager there is a simple workaround.
Open the XTE service configuration file:
C:\Program Files\Common Files\Citrix\XTE\conf\httpd.conf
You will need to scroll down about half way through the file to the <VirtualHost> section.
Now you will just need to add a line for your user or group:
require user “contoso.com\\bsmith”
require group “contoso.com\\PM Users”
Save the file and restart the XTE service. Your user should now be able to use the Password Manager console as well as the Password Manager plugin.
