If the application you're requesting Bluestem authentication for is in
the UIC domain and it accepts ness's default auth method, then all is well,
and you don't have to worry about domains or auth methods when you login.
That is the case for Grateful Med and will be the case for most services
that ness will provide authentication for.
However, domains or auth methods can present a small complication in
the Bluestem login process. It is quite possible, for example, that some
university-wide services will in be in the UIUC domain. (The UIC and UIUC
Bluestem servers know about each other and will accept authentication from
the other where appropriate.) And some applications might require specific
auth methods.
How do you tell the Bluestem server the domain or auth method that it should
use? Instead of typing just your netid in the login screen (see Figure
1), you use: netid@domain or: netid/authmethod
or: netid@domain/authmethod
How can you tell when you need to specify the domain or auth method?
The domain is easy - you need to specify it anytime the Bluestem login
screen doesn't say "University of Illinois at Chicago" or the URL displayed
doesn't begin with ness.uic.edu. In that case, you must include @uic.edu
with your netid.
I would use: bobg@uic.edu
(I could use bobg@uic.edu for my netid when I log into ness,
too. It's not wrong; it's just not necessary.)
Deciding when you need to specify an auth method is even easier. The default,
whatever it happens to be (it's TACACS now), will almost always work. And if
you ever use an application where it won't work, someone will tell you about
it ahead of time and will tell you what method you should use instead.
