Hi,

could you please provide a use case describing in which case we would

use it?

Thanks a lot :)

For example, Internet2 users might like to use "Internet2" authentication

federation, that is different than "GN2-perfsonar" one.

I think Jeff have a better idea how the use case would look like.

Yes, that is exactly the use case. Many of our universities for example are already part of the inCommon federation and are not likely to be part of the eduGAIN federation directly.

Now - I guess it is possible that an inCommon metadata service could know about the IdP's in eduGAIN and vise-verse. But - even in that case, I think it is a mistake for the location of the MDS to be encoded directly into client software. That creates a single point of failure situation.

Candido - can you comment on this? What do you think? Is there a reasonable way the MDS location can be dynamically fetched?

I think we should wait for this issue. Since the last DICE meeting two weeks ago, we're working on defining a common AA scenario for GN2 and organization from US, and until we get the final results, I'm not sure if we should get the MDS location dynamically. For now, I think we have what we need with the command line option.

I'll keep you up-to-date about the common AA scenario between GN2 and US.

Thanks,

Jeff,

I guess nobody had suggested this so far - otherwise I think it is very

good option.

Hi Nina, Candido,

Is there any reason we could not publish the metadata service URL in

the LS, and then fetch it from there? Hopefully there will be more

than one authentication federation in use soon and I suspect it will

be easier for users if they can be presented with choices instead of

making them specify things like this.

Thanks,

jeff
