In Identity Provider Setting page,  there is the option "HTTP-POST Binding for AuthnReques" .

When Switch this option, in the export xml , the value of  Binding for SingleLogoutService  and AssertionConsumerService

will be changed between HTTP-Redirect and HTTP-POST like this:

<SingleLogoutService Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect" ......>

 <AssertionConsumerService     Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect" Location=""         index="1" isDefault="true" />

I don't understand this because I think this binding method should be controlled by the "HTTP-POST Binding Response" .  

what do I misunderstand ?
