vCenter Server Single Sign On Session Using C#

After you obtain a SAML token from the vCenter Single Sign On Server, you can use the vSphere API method LoginByToken to establish a single sign on session with a vCenter Server. To establish a vCenter Server session that is based on SAML token authentication, the client must embed the SAML token in the SOAP header of the LoginByToken request. The C# LoginByToken example uses the following .NET services to support a single sign on session.

.NET Element / Namespace	vCenter Single Sign On Usage
SecurityPolicyAssertion Microsoft.Web.Services3.Security	The sample creates a custom policy assertion derived from the SecurityPolicyAssertion class. The custom assertion contains the SAML token and X509 certificate.
SendSecurityFilter Microsoft.Web.Services3.Security	The sample defines a custom output filter derived from the SendSecurityFilter class. The custom filter adds the token and certificate to the outgoing SOAP message.
ServicePointManager System.net	The sample uses the ServicePointManager to specify SSL3 and HTTP 100-Continue behavior.
ConfigurationManager System.Configuration	The sample uses the ConfigurationManager to specify certificate metadata (password and certificate type).
CookieContainer System.Net	The sample uses the CookieContainer class to manage vCenter session cookies.
