Radio buttons instead of a list box in the embedded DS?

[Rod Widdowson]

I was thinking about endpoint validation and the EDS.

If you were to have one EDS per SP (which is the design centre), you could
configure the EDS to run in "no parameter mode" (set defaultReturn to be
"\Shibboleth.sso\Login" (or whatever) and then point to it.  You might need
to enter an REF to make sure that it never looked at the standard DS
protocol parameters (as I recall the current behaviour is to look at the
parameters and fall back to defaultReturn).

You then get "built in" endpoint validation - you can only ever get sent
back to yourself.

I've mentioned how to use radio buttons.  

I'll also add that although much of this can be done statically, if you do
use the EDS you will get the "last selected" capability as well as the
option of auto-follow which might work quite well in such a constrained
environment.
