Diagnosis
Because of technical requirements, the endpoint &MSG1& can only use anHTTP destination.

System Response
SOAP bindings from the system can only be used over HTTPS from HTTPdestinations. The reason lies in the use of the SSL protocol. Thisrequires a certificate for the binding. Outbound SSL connections canonly go over HTTP destinations for this reason.

Procedure
In transaction SM59 create a destination with the prefix "SAML2_" oftype G (HTTP). For example, SAML2_SOAP. This HTTP destination requiresan SSL configuration, in which the client certificate for the connectionto &MSG1& is saved in the SSL PSE.

Procedure for System Administration
Use SM59, to create an HTTP destination of type G (HTTP) with the prefixSAML2_.
