Geneva and Streaming

Is it possibleto combineGeneva with Streaming?
If not, how can I transfer large amounts of data using Geneva?

You should be able to use a CustomgBinding on the WCF service with auth mode IssuedTokenOverTransport. Specify the issued token parameters pointing to the Geneva server endpoint.
Are you planning to use cardspace in this scenario?

Elena,

Do you mean streaming large SAML tokens that contain lots of claims? If so, there are other solutions to that problem besides streaming. Streaming isn't going to be possible w/ Geneva Server's STS because the API is defined by OASIS and it isn't compatible w/ the streaming requirements of WCF (e.g., the service's Issue operation doesn't return a Stream object).

If this isn't what you meant or if you can clarify, myself or someone else on the list will probably be able to help you more.

Thank you Travis,

I mean just small tokens, but large data.
For example, a 500MB file.

[ServiceContract]
public interface IStreamingSample
{
[OperationContract]
Stream GetStream(string data);
[OperationContract]
bool UploadStream(Stream stream);
}

I want to know, whether it's possible to have this Web Service with claims-based identity or not.

There are some restrictions for streaming:
"you can use only transport-level security options for streaming and you cannot turn on reliable sessions."
