When the SAML IdP is deployed in the private cloud, ASA and other SAML-enabled services are in peer positions, and all in the private network. With the ASA as a gateway between the user and services, authentication on IdP is handled with a restricted anonymous webvpn session, and all traffic between IdP and the user is translated. When the user logs in, the ASA modifies the session with the corresponding attributes and stores the IdP sessions. Then you can use service provider on the private network without entering credentials again.

In those cases you could simply add the "http" and "ssh" statements on the ASA to allow the management connections from specific hosts/subnets. Naturally if you dont manage the ASA externally from a specific IP address always then this might not be an option if you want to keep the ASA as secure as possible with regards to management connection options.
