It sounds to me as if the WACS is disabled, though you did mention earlier that it was enabled.
the SAML errors you get in the WACS logs are some I'm not familiar with. Have you set up any special authentication or do you log onto BOE using Enterprise authentication?
there is a Landscape Report Tool that is extremely helpful in creating a report of your entire landscape and it can also point out potential configuration problems. You can find the details in SAP Note: 2138275.
Use this tool to see if any anomalies show up. (based on the Corba GIOP error I suspect a port conflict there. The tool will show you all of the configured ports on your system).
Don't attach the report here as it will have internal information about your landscape
