CB-01: InCommon-based Authentication

Executive Summary: 
A campus IT administrator would like researchers at his/her campus to be able to login to XSEDE resources using InCommon-based authentication mechanisms.
User Importance Summary: 
XSEDE's campus bridging initiative is aimed at making it easier for researchers to access XSEDE services from their campuses, and easier for campus IT administrators to offer their services to other XSEDE users. A growing number of academic/research institutions offer InCommon credentials to their researchers and students. Allowing researchers to login to XSEDE resources using InCommon credentials makes it easier for researchers to move their work from campus-based systems to XSEDE resources and back again.
Target Communities and Sizes: 
Researchers at InCommon-participating institutions who use XSEDE services - (10000 < N < 99999)
