cdaefa:EFA Context Manager SFM

Method	openContext(credential Object) : ContextIdentifer fault AuthenticationFailedException
Description	This method establishes a security context for a user that wants to get access to an eCR peer. The security context holds the Identity Assertion [SAML2.0core] necessary for invoking service operations from business services. A credential MUST be passed.
Input Parameters	credential	Object which MAY be a username/password combination, a subject identifier, a health card handle, or a SAML assertion that guarantees for an authentication.
Return Value	ContextIdentifier	The identifier used to refer to the security context when issuing EFA activities within that context
Preconditions	Credentials (i.e., username/password) are present. No previously established security context with the same credentials is present.
Sequence (Main success scenario)	If a username/password combination is passed, the connector/ECRRequestor constructs a UsernameToken [WSSUsername] and invokes the RequestSecurityToken [WSTrust] operation of the eCR Identity Provider [eCR SecArch 1.2] for issuing an Identity Assertion. If a subject identifier is passed and a local Guarantor Token Service is configured, a local au-thentication assertion is issued and forwarded to the eCR Identity Provider. If the credential is already an Authentication Assertion, it will be forwarded as a security token to the eCR Identity Provider. If the authentication was successful, the Identity Assertion is stored in the session context within the eCR-Connector for later use. Otherwise an exception is thrown.
Exception	AuthenticationFailedException	Authentication failed due to wrong credentials.
