Sun Ray Software is capable of supporting Windows Network Level Authentication (NLA), but VMware View 4.5 does not support NLA on non-Windows based View clients. You must use the standard RDP authentication with VMware View 4.5.

Workaround: To configure RDP authentication, enable RDP authentication on the guest OS and add the -N off option to the uttsc arguments field in the Kiosk Mode tab within the SRS Admin GUI.

There are problems when typing some characters into Java 5 dialogs on Sun Ray.

Workaround: Install Java 6 on the Sun Ray server and modify the kiosk script to use Java 6 to execute the VMware View connector GUI.

The vdm-client.jar, after authenticating the user's credentials, starts the standard Windows connector uttsc script. The uttsc script launches the uttsc binary in a loop which attempts to detect how and why the uttsc binary exited. If the uttsc binary exits with a 0 exit code, the uttsc script will attempt to restart it rather than exiting. This avoids unnecessary kiosk sessions teardowns/recreates. However, in the VDM case, this causes an error since the password provided originally by VDM is good for one login only and the user's normal user name and password cannot be used.

Workaround: Remove the looping logic from the uttsc script and add it to the VDM script so that the vdm-client.jar is relaunched inside the existing Kiosk Session.
