CoSign single sign on
Encyclopedia
Cosign is an open source
project originally designed by the Research Systems Unix Group
to provide the University of Michigan
with a secure single sign-on
web authentication
system.
Cosign authenticates a user on the web server and then provides an environment variable for the user's name. When the user accesses a part of the site that requires authentication, the presence of that variable allows access without having to sign on again.
Cosign is part of the National Science Foundation
Middleware Initiative (NMI) EDIT software release.
