Hi,

 

Just want to clarify your needs.

 

  • You have one IDP hosted on one F5 (call it F5-A)
  • You have one application cloud that bind to this IDP (call it App-Cloud)
  • You have one Application hosted on onother F5 (call It F5-B) I suppose that you use F5 as SP in F5-B? then you perform SSO to the backend server? or your application is SAML Compliant and use F5 just to reverse this app?...

In general when you obtain "No Server Selected" that's mean that your internal APP do a request Auth without SAML request and mybe on the wrong URL. As your IDP session is still active, F5 consider your request as simple request and none SAML request and try to send your request to the backend server. And As you don't have an pool on this service (normal) you obtain this error: "No Server Selected"...

 

Did you perform a trace when this behaviour occur? in order to check if application send a correct saml request?
