On the Allowable SAML Bindings screen, you select the one or more bindings that your IdP partner can use to send SAML assertions or SAML 2.0 SLO messages.
This configuration applies to all SAML connections.
Select only the applicable SAML binding (or bindings) based on your partner
If you have specified an SSO or SLO endpoint using the artifact (outbound) binding, you must including SOAP as one of the allowable (inbound) binding.
If you are editing an existing connection, you can reconfigure the allowable bindings, which may require additional configuration changes in subsequent tasks.
