Server-wide RDP credential saving and SSDI auto RDP auth

[crsleeth]

Is your feature request related to a problem? Please describe. There is no way to save RDP credentials server-wide. Users have to re-enter their credentials at least once per RDP device. There should be an option for users to save their RDP credentials to be used server-wide on all RDP devices. This gets very tedious when you consider organization password change policies.

Additionally, there should be an option on SSDI enabled servers to use the credentials a user logins in with when connecting to RDP devices.

Describe the solution you'd like

1. Ability to save RDP credentials so they are applied to all of a user's devices server-wide
2. Ability on SSDI enabled servers to assume the credentials used to login will be used on all RDP devices server-wide

Describe alternatives you've considered When admins add devices on Apache Guacamole they can set the username and password to be ${GUAC_USERNAME} and ${GUAC_PASSWORD} which has Guac attempt to connect to RDP devices with the LDAP credentials used to log in to Guac. This makes it very user friendly and just one or two clicks to connect to desktops after login.
