PWLX_QUERY_IC_CREDENTIALS callback function (winwlx.h)

[The WlxQueryInetConnectorCredentials function is no longer available for use as of Windows Server 2008 and Windows Vista.]

Called by a replacement GINA DLL if Terminal Services is enabled. GINA calls this function to determine whether the terminal server is using Internet connector licensing and to retrieve credentials information.

Note   GINA DLLs are ignored in Windows Vista.
 
The GINA DLL can then use this information to fill in a logon box automatically and attempt to log the user in.

Syntax

PWLX_QUERY_IC_CREDENTIALS PwlxQueryIcCredentials;

BOOL PwlxQueryIcCredentials(
  [out] PWLX_CLIENT_CREDENTIALS_INFO_V1_0 pCred
)
{...}

Parameters

[out] pCred

When the return value is TRUE, pCred specifies a pointer to a WLX_CLIENT_CREDENTIALS_INFO_V1_0 structure that contains the credentials to use for auto logon.

Return value

The WlxQueryInetConnectorCredentials function returns one of the following values.

Return code Description
TRUE
Internet connector licensing is enabled.
FALSE
Internet connector licensing is not available.

Remarks

The GINA DLL is responsible for calling LocalFree to free the resources used by this structure when the structure is no longer needed.

In order to access this function, the GINA DLL must use the WLX_DISPATCH_VERSION_1_3 structure, and set the Winlogon version to at least WLX_VERSION_1_3 in its WlxNegotiate call.

If Terminal Services is not using an Internet connector license, the GINA DLL must call WlxQueryClientCredentials.

Other Winlogon support functions that may be called when Terminal Services is enabled are WlxDisconnect, WlxQueryClientCredentials, WlxQueryTerminalServicesData and WlxWin31Migrate.
