SOLE_AUTHENTICATION_INFO

[This is preliminary documentation and subject to change.]

Identifies an authentication service, authorization service, and the authentication information for the specified authentication service. The SOLE_AUTHENTICATION_LIST structure, which is pointed to by the pAuthInfo parameter of CoInitializeSecurity, contains an array of SOLE_AUTHENTICATION_INFO structures.

typedef struct  tagSOLE_AUTHENTICATION_INFO {
        DWORD dwAuthnSvc;
        DWORD dwAuthzSvc;
        void *pAuthInfo;
    } SOLE_AUTHENTICATION_INFO;
 

Members

dwAuthnSvc

The authentication service. It may contain a single value taken from the list of RPC_C_AUTHN_xxx constants defined in rpcdce.h.

dwAuthzSvc

The authorization service. It may contain a single value taken from the list of RPC_C_AUTHZ_xxx constants defined in rpcdce.h.

pAuthInfo

A pointer to the authentication information, whose type is specific to the authentication service identified by dwAuthnSvc. For SSL (RPC_C_AUTHN_GSS_SCHANNEL), this member points to a private certificate that will be used for authentication in the form of a CAPI handle. For NTLMSSP and Kerberos, this member points to a SEC_WINNT_AUTH_IDENTITY_W (or SEC_WINNT_AUTH_IDENTITY_EXW) structure containing the user name and password. For authentication services that DCOM doesn't know about, pAuthInfo must be set to NULL. For more information, see COM and Security Packages.
