You should look at Shibboleth (http://shibboleth.internet2.edu/) and
http://www.incommonfederation.org/  from I2.    One design consideration
is the minimizing the number of trusted places a user/key pair needs to
be accepted so you can reduce exposure from a rouge application.

 

The big trust issue is making sure you trust the processes and standards
the other organization asserts. 
http://www.incommonfederation.org/docs/policies/incommonpop_20080208.htm
l has the good insight into that processes. It’s also designed that you
need to trust on a peer-to-peer level that someone’s practices are good
enough to trust since identity processes are much different from place
to place.

Subject: [SECURITY] Multiple campus SSO security requirements

 

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.

Thanks,
