Hello, We are considering multi-campus web-SSO system that allows an end-user to authenticate using their home campus LDAP account or another campus LDAP account they may hold Has anyone implemented such a system and how have you dealt with the trust issues between campuses that this creates? For example, each campus may have their upfront ID-issuing or vetting process reviewed by all the other campuses and an agreement signed before they are allowed to participate, as in a federation. Any thoughts on this issue would be welcome.
It sounds like you want to create a system wide federation. Several public state higher ed systems have already done this (eg see UCTRUST, the Texas system, the NC system, etc). Sometimes the statewide federation also includes state and local government; sometimes the plans also include bringing in K12 at some point. You'd want your federation to set "common policy" for the members. This might be a higher bar than is currently set by InCommon. It might be useful, tho, to look at the recently promulgated InCommon "Silver" standards, which match the federal e-authn Level 2 (and will grant access to applications such as NIH grants mgmt, and (eventually) Dept of Education FERPA). As a starting point, each campus would likely have some people at "bronze" level, and a smaller set at Silver (people who need to access applications in ways that engender a higher level of risk).
