IDM-14: SSH access using a community identity for education

Executive Summary: 
An educator needs his/her students to be able to login via SSH with their community identities to a virtual machine (VM) he/she administers so they can use the VM and the educator doesn’t have to assign new IDs and passwords or SSH keys to every student.
User Importance Summary: 
Using VMs in education and training is an important way to broaden use of the public research computing community and prepare the next generation of community members. Improving the ease of use for students and minimizing "busy work" for instructors is important toward making this happen.
Target Communities and Sizes: 
Educators who use VMs and public research resources - 100 < N < 1,000
