Microsoft VPN Client settings
AuthLite can work with the pre-installed VPN client that ships with Windows, and requires a minimum of configuration on the client side.
Username field retention
The Microsoft VPN client saves the last entered value from the username field by default. If you are using the Username field for OTP entry, then you may wish to change this behavior (so the user doesn't have to remember delete the string each time to enter a new OTP).
If you manage the workstations, you can set the following registry value:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters] "DisableSavePassword"=dword:00000001
Although its primary use is to disable the option of saving VPN passwords, it also has the effect of clearing the username field.
