ITSGPolicyEngine::AuthorizeResource method (tsgpolicyengine.h)

  • Article

Determines which resources the specified connection is authorized to connect to.

Remote Desktop Gateway (RD Gateway) calls this method after a user has been successfully authenticated. The authorization plug-in should then use the ITSGAuthorizeConnectionSink interface to notify RD Gateway about the result of authorization.

Syntax

HRESULT AuthorizeResource(
  [in] GUID                      mainSessionId,
  [in] int                       subSessionId,
  [in] BSTR                      username,
  [in] BSTR                      *resourceNames,
  [in] ULONG                     numResources,
  [in] BSTR                      *alternateResourceNames,
  [in] ULONG                     numAlternateResourceName,
  [in] ULONG                     portNumber,
  [in] BSTR                      operation,
  [in] BYTE                      *cookie,
  [in] ULONG                     numBytesInCookie,
  [in] ITSGAuthorizeResourceSink *pSink
);

Parameters

[in] mainSessionId

A unique identifier assigned to the connection request by RD Gateway.

[in] subSessionId

A unique identifier assigned to the subsession by RD Gateway. A subsession is a session launched from another session.

[in] username

The user name.

[in] resourceNames

A list of resources to authorize.

[in] numResources

The number of resources referenced by the resourceNames parameter.

[in] alternateResourceNames

A pointer to a BSTR that contains a list of alternate resource names. This parameter is only valid when RD Connection Broker is in use.

[in] numAlternateResourceName

The number of alternate resource names referenced by the alternateResourceNames parameter.

[in] portNumber

The port number specified by the user.

[in] operation

The operation that the user is attempting on the resource. This parameter is always set to "RDP".

[in] cookie

A pointer to a BYTE that contains the cookie provided by the user. If the user did not authenticate by using a cookie, this parameter is NULL.

[in] numBytesInCookie

The number of bytes referenced by the cookie parameter.

[in] pSink

A pointer to an ITSGAuthorizeResourceSink interface that the authorization plug-in must use to notify RD Gateway about the result of authorization.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

If this method returns S_OK, RD Gateway waits for the authorization plug-in to call a method of the ITSGAuthorizeResourceSink interface. If any other value is returned, RD Gateway immediately denies the authorization request.

If authorization requires more than 1 second, we recommend starting a separate thread to perform authorization.

For a sample that uses the AuthorizeResource method, see the Remote Desktop Gateway Pluggable Authentication and Authorization sample.
