Hi Ruchith,
Please ignore my last email, I was just doing something really silly. I have
managed to send a request to the STS service but I get a "Unsupported
WS-SecureConversation version" response back, I think I shoul be able to work
that out.
Regards,
Hardev

Hi Ruchith,
I used the config files from
http://wso2.org/repos/wso2/trunk/wsas/java/modules/samples/sts-sample/conf/
and copied the sts.policy.xml to services.xml and try and run the STS service
but I get an "invalid services.xml".

I have an STS service running from sample05 and so I tried to run the Client
against that but I run into encryption problems, the reason I think is that I
am not setting up the client keystore with the correct keys ( I am using the
keystore from sample 05) as I don't have access to the files needed to build
the client keystore as defined in build.xml from
http://wso2.org/repos/wso2/trunk/wsas/java/modules/samples/sts-sample/conf/
Hope you can help with this.
Thanks,
Hardev

Hi Hardev,
Your messages exchanges sounds fine up to the point where the callback
handler accesses the STS to obtain the symm key. IMHO WS-Trust doesn't
provide a specific way to obtain a key at this point of a standard
WS-Trust exchange.
We have you use case implemented in a slightly different approach:
- Client contacts the STS and obtains a SAML token to talk to a service
- The STS includes a symm key encrypted for the service within the SAML token
- The RSTR (response from the STS to the client) will have that *same*
symm key for the client to extract
- (When using Rampart/Rahas the client uses
org.apache.rahas.client.STSClient which will extract this information
and bundle all of it into a org.apache.rahas.Token instance)
- Now this SAML token (assertion) will be added to the Security header
of the message from client to service and the symm key that is
associated with the SAML token will be used to encrypt/sign the
message as specified by the service policy.
- At the service the SAML assertion in the Security header will be
processed and the symm key will be extracted.
- Processing at the service will use this extracted symm key to
decrypt/verify signature where necessary.
A sample client that does this sort of a message exchange is available
here : [1]
Now ... SCT usage scenario is usually a WS-SecureConversation scenario
where rampart/rahas supports the application service it self to act as
an STS. In this case since the service and the STS both are the same
the symm key created is known at the service, and it is not included
in the SecurityContextToken (SCT) itself. Are you sure you want to use
this SCT scenario in the context of WS-SecureConversation or are you
looking for a pure WS-Trust scenario as I explained above.
Thanks,
Ruchith
