IWMSAuthenticationPlugin::GetFlags
The GetFlags method retrieves any flags that identify the challenge and response mechanism used by the plug-in.
Syntax
HRESULT GetFlags( long* pFlags );
Parameters
pFlags
[out] Pointer to a long containing a member of the WMS_AUTHENTICATION_FLAGS enumeration type. This must be one of the following values.
| Value | Description |
| WMS_AUTHENTICATION_TEXT_CHALLENGE | The challenge and response BLOB contains only text. |
| WMS_AUTHENTICATION_CLIENT_SHOWS_UI | The client prompts the user for credentials. |
| WMS_AUTHENTICATION_ANONYMOUS | Anonymous authentication does not retrieve credentials from the client. |
| WMS_AUTHENTICATION_CHALLENGE_FIRST | The server initiates the authentication process and generates the challenge BLOB first. |
Return Values
If the method succeeds, the plug-in must return S_OK. To report an error, the plug-in can return any HRESULT other than S_OK. If the plug-in uses the IWMSEventLog interface to log error information directly to the Windows Event Viewer, it is recommended that it return NS_E_PLUGIN_ERROR_REPORTED. Typically, the server attempts to make plug-in error information available to the server object model, the Windows Event Viewer, and the troubleshooting list in the details pane of the Windows Media Services MMC. However, if the plug-in uses the IWMSEventLog interface to send custom error information to the Windows Event Viewer, returning NS_E_PLUGIN_ERROR_REPORTED stops the server from also logging to the event viewer. For more information about retrieving plug-in error information, see Identifying Plug-in Errors.
