question principle propagation wtih XI 3.0
we have a SAP XI 3.0 SPS 18.
for the following scenario I have a question.
From DataPower should a message with a LTPA or SAML2 Token (User Context) via XI to an SAP-System.
Does this work? Could XI 3.0 handle LTPA or SAML2 Token?
Where can I find Information for principle propagation and which standards like SAML or LTPA are supported?
