The end user/browser only sees the initial service ticket, the proxy granting ticket and then the proxy ticket are only provided to the application the end user initially authenticated to, which also becomes a "client" per se when it accesses another application via proxy on behalf of the original end user.</p> <p style="margin: 10px 0 0 0">I'm sure more than one PT could be stored using the data sealer, but then the question becomes how many and how to decide when to stop? It could be configured either by a certain ticket size, so as many members of the chain that fit in the size will be encoded, or by a number, where X members of the chain will be encoded. As that value gets increased, presumably eventually something would break. And probably different things would break at different sizes.</p> <p style="margin: 10px 0 0 0">I originally thought about such an implementation, but decided the increased complexity wasn't really worth it given proxy chains of more than one member aren't that common. The current approach supports clustered idps without shared storage for the most common use of proxy granting tickets with minimal additional complexity or likelihood of breakage. It could certainly be extended at some point in the future to be more general or support chains with more than one member if that use case became important enough to somebody.</p> </td>
