Deleteing a security group

Hi,

I recently moved our RDPM Database to a new SQL Server and switched to ad integrated security (no more local users, finally:) )
We have some old security groups we dont need anymore with a few sessions assigned to them:

- What happens to those sessions if I delete the group? Are they switched to no group?
- Is there a way to see all sessions assigned to a certain group?


And also a feature request.
Adding several users form ad was really annoying.
Every time I have to switch from my local machine to the domain manually and then I can only add one user at a time and no groups.
Maybe I did something wrong and didnt see the option?

Thank you
