This structure identifies an authentication service that a server is willing to use to communicate to a client.

This structure is passed by servers to CoInitializeSecurityas a member of the asAuthSvcparameter and can be retrieved through a call to CoQueryAuthenticationServices.

Syntax 

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

Members

dwAuthnSvc

The authentication service.

It can contain a single value taken from the list of RPC_C_AUTHN_ XXXconstants. RPC_C_AUTHN_NONE turns off authentication.

dwAuthzSvc

The authorization service.

It can contain a single value taken from the list of RPC_C_AUTHZ_ XXXconstants.

This parameter is ignored when using the NTLMSSP (RPC_C_AUTHN_WINNT) authentication service and should be none when using SChannel (RPC_C_AUTHN_GSS_SCHANNEL), Kerberos (RPC_C_AUTHN_GSS_KERBEROS), or Snego (RPC_C_AUTHN_GSS_NEGOTIATE).

pPrincipalName

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 that contains the server's certificate. It cannot be NULL.

hr

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