Add ability to add/modify SMB users

[RaidOwl]

Is your feature request related to a problem? Please describe. It's not really a "problem", but more of a necessary feature. There isn't a way to add users to access a SMB share.

Describe the solution you'd like Currently, there is no way to add a user for SMB access to a shared folder. I would like some way to do this in the GUI rather than manually in the console. It doesn't have to be an extensive permissions GUI but something to just simply add/modify users for access to shared folders would be nice.

Describe alternatives you've considered

I would be very intrested in this as well. It's great that we can easily set up shres however, it would be great to have the ability to at least require authentication even if its just the casa os account doing the authentication
