Thanks, this was helpful.
Right now I see that the osgeo.org has three cookies in my cookie cache.
Two that are apparently session ids, and one called "MDAAuth" that
has the contents:
"78fe1....d2888b07879f2442d6d9dwarmerdam at pobox.com!8000!"
I am guessing that when I visit a page at osgeo.org, the MDAAuth
cookie is checked against some sort of database to see if I am logged
in and if so, who I am. Is that right?
Would the "SSO" proposal be to provide a service whereby external
components of the osgeo.org domain (ie. wiki.osgeo.org) could
authenticate the same cookie? Forgive me for being a bit dense.
This isn't my area of specialty.
My generally impression is that sharing login information stuff between
outside components and the CN provided systems is going to be pretty
involved. Perhaps for now we could pursue a "two signon" solution
where the external systems are run off a central LDAP server at
telescience. At least that would be more managable than separate
userid silos for every external service.
