SOLE_AUTHENTICATION_SERVICE structure (objidl.h)

Identifies an authentication service that a server is willing to use to communicate to a client.

Syntax

typedef struct tagSOLE_AUTHENTICATION_SERVICE {
  DWORD   dwAuthnSvc;
  DWORD   dwAuthzSvc;
  OLECHAR *pPrincipalName;
  HRESULT hr;
} SOLE_AUTHENTICATION_SERVICE;

Members

dwAuthnSvc

The authentication service. This member can be a single value from the Authentication Service Constants.

dwAuthzSvc

The authorization service. This member can be a single value from the Authorization Constants.

pPrincipalName

The principal name to be used with the authentication service. If the principal name is NULL, the current user identifier is assumed. A NULL principal name is allowed for NTLMSSP, Kerberos, and Snego authentication services but may not work for other authentication services. For Schannel, this member must point to a CERT_CONTEXT structure that contains the server's certificate; if it NULL and if a certificate for the current user does not exist, RPC_E_NO_GOOD_SECURITY_PACKAGES is returned.

hr

When used in CoInitializeSecurity, set on return to indicate the status of the call to register the authentication services.
