Activating users/groups can be done in multiple ways:
- Using AllowUsers/AlowGroups directives globally - requires that user does have a Windows profile directory
- Create a match block for a specific user/group (you can use directory isolation to specify a specific directory instead of user profile directory)
Copying public key can be done via Tools -> Copy public key. It uses the tool ssh-copy-id. You can use localhost to contact the copssh server.
