Provide support for Kerberos Constrained Delegation (S4U2Proxy, S4U2Self) in WebSphere Full Profile

With JDK 8 the S4U2Proxy and S4U2Self mechanisms are implemented in the GSSApi for delegated access with credentials of the client to backend servers with Kerberos.


Currently WebSphere Application Server 8.5.5 and 9beta do not provide APIs or Support for delegating credentials via S4U2Proxy and S4U2Self in a Kerberos authenticated Installation.

In Liberty Profile the S4U2Proxy, S4U2Self mechanisms are supported but this is not the case in Full Profile and seems not to be provided with the new Version 9 of Full Profile.

It would be very helpful, if the Full Profile supports constrained delegation too.
