cmc_logon failed with outlook 2002

[Laurent]

Hi,

I use the cmc_logon function to log a client application
to a service provider but the following code failed :

if ((ulResult = CMCLogon
(NULL,NULL,NULL,0,0,CMC_VERSION,CMC_LOGON_UI_ALLOWED
|CMC_ERROR_UI_ALLOWED,&lhSession,NULL))==CMC_SUCCESS)

the return code is CMC_E_FAILURE

This logon works correctly with Outlook 2000

Thanks,

Laurent.
